|9/23/2012 14:55:15||Janica Henzie||I couldn't see the class data, but I think the names go in alpha order, boy-girl-boy, etc. But, I could be wrong.||northern hemi: the hurricane's originate over the ocean near equator and then move northwest then east; the combination of forces (wind patterns, earth's rotation, its spin and momentum) that causes the hurricane to move toward the pole||hurricanes form during the warmer months - summer and fall - due to the sun's heat||counterclockwise in northern hemisphere; due to the earth's rotation||the greatest risk of hurricane on land would be the southeast since that is in the path from equatorial waters and the path of the storm to the pole||without viewing the class data, I don't have a way to answer this; I do know that the strength of the storm decreases on land|
|9/23/2012 21:55:37||Jung Choi & Terry Johnson||During the early years, hurricanes were named after women but in 1978, meteologists began sing men's names for half of the storms. During even numbered years, men's names were given to the odd-numbered storms and during odd-numbered years, women's names were given to odd numbered storms.||A hurricane forms in the southern Atlantic Ocean, Carribean Sea, Gulf of Mexico, and in the eastern Pacific Ocean. All Atlantic and Gulf of Mexico coastal areas are subject to hurricanes although not all hurricanes will end up in coastal and inland areas. Hurricanes are formed over the ocean and end up moving clock wise.||Counter clock wise. Caused by the earth's rotation and the Coriolis Force.|
|9/24/2012 14:18:14||Jung Choi/Terry Johnson||Part I ( Names, spin, movement) already submitted...please, look for the answers.||Summer and Fall|
Hurricanes feed on heat that is released when moist air rises. Therefore, hurricanes are most common when an area of sea is at its warmest( June to November).
|The risk of hurricanes are greatest around the coastal area where the warm ocean water is readily available to feed a traveling hurricane. Below-sea level cities are in danger of getting flooded. Louisiana, Florida, N Carolina and Coastal Mississippi in US are on the list of most vulnerable areas. Storm surge and freshwater flooding potential as well as coastal erosion trends add to the risk of hurricanes.||When a hurricane travels over land or over cold water, its energy source is no longer available, so the storm weakens, leaving a weak weather system that can produce a lot of rain. Category 1, 2 maybe near the land or over cold body of water when 3, 4, 5 will be near warm and evaporating water near equator.|
|9/24/2012 21:26:55||Megan Whitaker||Hurricane names switch back and forth between male and female names and sometimes seem to be going through the alphabet in order.||Most hurricanes seem to start on or just north of the Equator, especially in the Atlantic near the coast of Africa. Many hurricanes move north west towards the Caribbean Sea, from there turning north again towards the Gulf Coast of Mexico and the United States. Once they hit land, they start to hook East across the United States and into the North Atlantic. This pattern of movement could also be caused by the movement of the currents coming north from the Equator and south from the North Atlantic. The warm air from the Equatorial region could be pushing the hurricanes north by building up pressure behind them.||Hurricanes seem to happen during the summer and fall because that is when the sun has heated up the Equatorial region of the Atlantic Ocean the most, increasing the amount of air motion due to convection currents.||Hurricanes appear to spin in a counter clockwise direction. This could be because of the convection currents in the atmosphere within a hurricane cycling up and down while the Earth is spinning on its' axis, causing the air to move in a circular patter.||Most hurricanes make landfall across the islands of the Caribbean and then into the Gulf Coast states of Texas, Alabama, Louisiana, Arkansas, and Florida. The risk is greater here because this part of Southern United States sits close enough to the warmer parts of the Atlantic to still be within the convection current zones where the warm tropical air is being pulled into the hurricanes.||When the hurricane starts, it is usually a category 1 as it is building in size and speed. As is begins moving north towards the Gulf Coast, it increases in size and speed, reaching up to Cat 5. As it approaches land, it may stay as a Cat 4 or 5. Once it is no longer over the ocean, the storm loses some of its strength, going back down to a Cat 2 or 1, and finally becoming a Tropical depression or extra tropical storm.|
|9/25/2012 16:35:28||Chelsey Traylor||All of the hurricanes are named using men and women names. Sometimes, the names are re-used in different years.||Many of the hurricanes originate on the eastern side of the United States and South America. Many of the hurricanes have a northern origin and finish at a location that is south of the origin. Many of the hurricanes have a windy like movement as it movees to the left then the right or vice versa. These patterns might be due to the seasonal weather patterns of the specific parts of the United States and South America.||Many of the hurricanes are during the summer months and into September and October. Hurricanes might be more prevelant during these months as a result of the hotter weather as the Sun is closer to the equator.||The hurricanes look like they are spinning in a counter-clockwise direction. This might be due to the wind patterns and the high and low pressure systems in certains areas of the world.||It seems that the southern states on the eastern side of the United States and the Carribean experience the most amount of hurricanes on land.||The less powerful hurricanes (category 1,2,3) are found over land in which the wind speed seems to decrease. The more powerful hurricanes appear over the water.|
|9/26/2012 1:09:41||Maria Anaya||I noticed that the name of my hurricane “Fran” was used every 2-4 years.||Most of the hurricanes we observed originated near the Caribbean and moved north curving to the right. The movement of the hurricanes is possible being affected by the prevailing westerlies at 30 degrees North. Many hit the southeastern part of the United States. ||Most of the hurricanes we observed developed in the month of September when the tropical oceans are the warmest providing the warm air that will rise to develop into a low pressure system.||They appear to spin counter-clockwise. This is due to the Coriolis effect that causes the air to turn counter-clockwise in the Northern Hemisphere.||The highest risk for hurricanes would be North America, specifically the state of Florida. The possible dangers are the storm surges leading to casualties and billions of dollars worth of damages.||Hurricanes are categorized by their wind speed. A category 1 has wind speeds of 74-95 mph, category 2 has 96-110 mph winds, category 3 has 111-130 mph winds, category 4 has 131-155 mph winds, and a category 5 has winds greater or equal to 156 mph. We observed that most hurricanes decreased in strength as they hit land. This is due to the lack of warm air from the surface waters that provided its energy.|
|9/26/2012 11:18:04||Mary Eckel||The hurricanes seemed to be named half for females and half names for males.||According to the class data most of the hurricanes originated in the Caribbean near Mexico. This may be because many of the storms do not reach tropical storm levels until they move from the coast of Africa across the Atlantic Ocean and build up strength.||Most of the hurricanes form in August and September. I think this has to do with warmer ocean temperatures at the end of the summer, which makes the conditions for tropical storms and hurricanes more favorable.||The hurricanes appear to spin in a counterclockwise direction. This is do to the rotation if the Earth which causes the Coriolis force.||Florida seems to be have the greatest risk of hurricanes. 33% of the hurricanes that were investigated by the class hit Florida. This is primarily do the location of Florida, it tends to be in the path of many of the hurricanes and tropical storms. Only 3% of the hurricanes made landfall in North Carolina, Louisiana or Texas. In Mississippi and South Carolina only 2% of the hurricanes made landfall and 4% of the hurricanes investigated did not make landfall in the US.||All of the hurricanes that the class investigated should have reached a category 5 at some point. The strength of the hurricane varies as the storm moves across the Atlantic. Most of the time the hurricane gains strength as it is moving over warmer water and then quickly diminishes as the storm makes landfall.|
|9/26/2012 13:53:51||Tiffanee Reynolds||They seem to switch off between male and female names, they appear to be named in alphabetical order, and the names appear to be used repeatedly over time.||Most hurricanes originate over the central Atlantic, in the NE Atlantic near Cape Verde Islands and West Africa, and the Carribean near Mexico. Most of these hurricanes make landfall along the Gulf Coast and East Coast of the United States. The hurricanes typically originate in the Atlantic ocean, gain wind speed, slow down as they reach land, and curve to the right. I think the wind speed of the hurricane slows down as it reaches land because its supply of evaporating water decreases, and it curves to the right due to conflict with areas of high pressure.||Hurricanes occur in summer and fall, with the greatest number taking place in late summer and early fall. I think this is due to the water of the Atlantic reaching its highest temperature during this time.||Hurricanes spin in a counter-clockwise direction. This is due to Coriolis force, which as a result of the earth's rotation, deflects air currents to the right in the northern hemisphere. It deflects air currents to the left in the southern hemisphere, which results in cyclones rotating clockwise in this area.||The risk of hurricanes is the greatest along the Gulf and East coasts partly due to the proximity of these areas to the equator. The water over the Atlantic reaches its highest temperatures in the summer and fall. As a result, the air over the Atlantic is warm as well. This warm, moist air rises up leaving an area of low pressure below. High pressure in the surrounding areas moves to the area of low pressure, and it too becomes warm and moist. As the new air enters the area of low pressure, it starts to swirl, and as the warm, moist air rises it cools and forms clouds. The tropical storm continues to pick up warm water over the ocean causing it to increase in size. When the winds reach 74mph it is considered a hurricane.||The hurricane starts out weak. As it picks up strength over water, it can quickly move from a category 1 to a category 2 or 3. However, when it hits land, it quickly looses strength and goes down in categories. For example, the 2005 hurricane Katrina was a category 5 hurricane in the Gulf of Mexico. As it reached land, it reduced to a category 4. Soon after hitting land, it reduced to a category 3.|
|9/26/2012 15:18:17||Tara Alton||Names are nearly evenly split, male and female.||Although it was hard to tell from looking at many of the hurricane pathways, hurricanes originate in the northeast Atlantic, near the Cape Verde Islands and West Africa, move West and dissipate as they move move over land. They may move in this direction because of the trade winds.||Hurricanes occur most frequently in August, September and October. This might be because these are the warmest months and warm water is a key component in the formation of hurricanes.||Hurricanes appear to spin counterclockwise. This can be explained because hurricanes air will move from high to low pressure and differential speed will cause it to spin (but not sure why counterclockwise...)||In the US, risk of hurricanes is the greatest in Florida and to an extent, the other states on the gulf and south eastern coast of the US. This is because hurricanes lose momentum as they travel over land so the risk is greatest where they first hit land.||A hurricane is most likely to be a category 5 over sea and to drop off rapidly once it hits land.|
|9/26/2012 16:11:46||Richard Hanley||The names are alphabetical and contain both masculine and feminine names.||Hurricanes begin in areas of lighter falling air which occur at 30 degrees north latitude and move south in a clockwise fashion and slow over land. They terminate before the equator.||The equator is warmest during late summer months causing unequal heating and cooling both there and at 30 degrees north and south.||Counterclockwise. As global wind patterns cause clockwise spinning air at 30 degrees north latitude, it (and the spinning of the Earth) cause the opposite spin in hurricanes. This causes falling air which is less dense than the surrounding air and causes dense air to be drawn into that vortex.||Southeastern coast below New York.||The storm's strength increases as it draws closet to land and slows upon arrival due to warmer, less dense air being drawn into the storm rather than wetter air over the ocean.|
|9/26/2012 16:22:05||Kenneth Mok, Denise Randol||The destructiveness of the hurricanes seems to be split evenly between male and female names.||From the data, the hurricane origins seem to come from mostly from the Carribbean near Mexico. This area seems popular because the U.S. weather radar would be most interested in tracking the future movements from the aforementioned location.||Starting from June, and ending in November, is the prime time for hurricane season. This is the the time of the year when the water and air patterns are the most idea to create a hurricane.||Counterclockwise; because we are in the Northern Hemisphere.||Florida is the state were the risk of hurricanes are the greatest. The location and the shape of Florida makes the state the most vulnerable to hurricanes.||Prior to landfall, the hurricane is at its greatest strength. Once the hurricane contacts land, the hurricane immediately decreases in strength.|
|11/3/2012 22:27:15||Denise Randol||Names of hurricanes tend to be two or three syllables. They used to be all female, until they introduced male names and now they alternate alphabetically, starting with A. The names seem to be American or Latin American type- which seems fitting since this is the area where the hurricanes appear. Do they name the cyclones that appear in the Indian Ocean?||The majority of the hurricanes travel in a curving clockwise path that hooks, especially when making landfall.|
Hurricanes in the Atlantic begin as tropical depressions just west of Africa and travel in the E to W ocean current towards the Caribbean. They either enter the Gulf of Mexico and curve north into Mexico or Texas, or veer east and encounter the Gulf coast states of Louisiana, Miss. or Alabama.
If the Hurricane turns north before passing Florida, then it heads up the east coast of the U.S. It often goes as far as the North Carolina 'bump' and hooks back out to sea, or continues up the coast and can affect states as far north as New England (last year's Irene).
I think the direction is affected by descending weather from North America, and the path can be altered by land such as the Yucatan peninsula or the coast of North Carolina. This can slow down a storm's energy.
|Hurricanes occur mostly in warm months, most frequently in August and September. The season starts in June and doesn't end until October. It is fueled by ocean temperatures. As long as the water is 84 degrees or warmer, then there is enough energy to create a tropical system. |
The west coast of North America does not get hurricane systems because the Pacific Ocean's Alaska Current comes north along the coast and keeps the water cool. Warm water is found in southern Baja. Sometimes in August and September we in Los Angeles get residual monsoonal humid conditions from tropical storms near Cabo San Lucas (this year was especially disgusting).
|Hurricanes appear to rotate counter clockwise. The direction seems to be affected by the upper level winds, the rotation of the earth and ocean currents.||Hurricanes occur along coastal land and islands in the Gulf of Mexico, Caribbean and Eastern coast of the U.S. The waters are very warm during the summer, traveling north west from the equator and west from Africa. The land along these coasts are tropical wetlands and flat beaches. This topography makes these areas vulnerable. Areas with denser vegetation act as a barrier, but because these are heavily populated (esp. in Florida and the Carolinas), the potential risks to humans and property is more acute.||Hurricanes gradually increase in strength. It is strongest over water and loses energy over land. The pattern looks like it takes several days to reach hurricane strength and then it can slow and speed up as it travels over water and islands. It can slow down crossing Cuba, for example and then pick up speed as it enters the Gulf. It can gradually slow as it heads north until it hooks out to sea near North Carolina and then regain strength and curve back up the coast and impact Maryland Delaware, Pennsylvania and New York.||The relationship between air pressure and windspeed is inversely proportional. When the air pressure drops, the wind speed increases. Less pressure creates conditions for movement of more air particles. I always notice increase in wind as a low pressure system is approaching. Cooler air that is sinking in a downdraft also pushes air.|

The hurricane is probably moving in the direction of the Coriolis Effect.||They mostly happen during Fall. It might be because the tropical season increases the temperature of the ocean and causes the beginning of a hurricane.||Most of them are counterclockwise. The Coriolis Effect causes the direction of the spin.||It is greatest around Louisiana and Florida. Those states are closer to the ocean near the equator where the hurricanes start.||I think when the hurricanes hit land, the strength increase enormously.||They are inversely proportionate. When one went down, the other would go up and vice versa.|
|10/22/2013 23:04:42||Todd Fletchall||Multiple Ike's||Origin in NE Atlantic. More warm regions that heat water in the area. Hurricane hooks clockwise but is more evident once it hits land.||September and October. The water takes the hotter months to increase in temperature. By the end of the summer sufficient time has elapsed for ocean warming to occur.||Counterclockwise||The Gulf coast appears to have the most occurrences. The warmer climate in the Gulf coast combined with tropical moisture from the equator causes sufficient pressure to form.||The highest categories are over the ocean. Warm water feeds the hurricane increasing its strength. The categories lower over land due to lack of warm water.||There seems to be an inverse relationship. Decreased air pressure creates a downward effect, pulling the air down increasing the speed.|

|10/25/2013 15:33:19||Andrew Salg||The pattern of the names seem to start out in alphabetical order, and are named after people||The origin of most hurricanes happen in the middle of the ocean or slightly off the coast of land. Hurricanes seem to move towards large parts of land with water around them. The spin of the hurricane will effect movement and where it makes landfall. Winds could also change the direction or changes in temperature around the storm.||Hurricanes form around late summer, this is because of the cold air high above, and the warm sea air rising. The warm sea air is what really makes a hurricane because during other seasons the air won't rise as high as it does in summer.||The direction hurricanes appear to spin is counterclockwise. This is because of the winds from the equator. Air from way above the earth's surface, and the warm sea air rising to create the spin.||Florida seems to be the highest risk of hurricanes. This is because they are a peninsula which exposes them to warm currents of ocean water. Warm ocean water will force the air to rise in the air, and cold air in the Atlantic combine to form a hurricane. Equatorial winds will also push the hurricane towards the west, but with a slight curvature.||The pattern of hurricane strength as a cat 1 starts around a little after its origin point in the ocean, but as it enlarges in size and speeds up it quickly goes up to 2. Cat 3 could be a quick step for some, but it will still be far away from land. Cat. 4 happens right before it reaches shallower water than the deep ocean. Cat 5 is most likely to happen when the current from land and the ocean meet where the ocean becomes shallower.||Air pressure will be inverse to wind speed. This is because as speed picks up the hurricane can not keep itself together making it easier to the storm to break apart. When air pressure increases the storm condenses in size, but will also slow down slightly causing the storm to stay more whole.|
|10/26/2013 9:25:19||Rick McMahan||According to http://geology.com/hurricanes/hurricane-names.shtml, hurricanes in the Atlantic have been named for hundreds of years and those in the Caribbean have been named for saints. After 1953, hurricanes were named after men and women when that method was employed by WW II meteorologists to track Pacific ocean storms during the war. Men's names began being used for Atlantic storms in 1979. Some names are retired if the hurricane in question causes so much death and destruction that re-using their names would be insensitive (such as "Katrina").||Hurricanes that originate in the Tropics follow a westward movement due to easterly winds that push the storm through the Atlantic and Caribbean oceans. These paths are generally due to high pressure in the Azore-Bermuda area but when the pressure is weak, they may follow a northern path as they follow the low pressure trough.||Hurricanes mostly develop in the summer or early fall due to the need for warmth which allows for warm ocean water to supply fuel for atmospheric changes that result in severe weather.||Hurricane spin is due to the Coriolis force which is directed by the earth's spin and causes hurricanes to spin in a counter-clockwise manner in the northern hemisphere and clockwise in the southern hemisphere.||Hurricanes are most likely to make landfall in south Florida, North Carolina, mouth of the Mississippi and southern Texas.||Hurricanes are most likely to strengthen over water where they are fed by moist tropical conditions resulting high winds (H5, H4, H3). As Hurricanes make landfall, they weaken due to lack of water which results in lower winds and thus weaker designations for strength (H1 & H2).||Low barometric pressure and high wind are generally assumed when discussing hurricanes. However, pressure is lowest in the hurricane eye where winds also fall dramatically. Winds will increase as one leaves the eye wall.|
|10/26/2013 19:00:23||Michelle Kirk||They go in alphabetical order and restart at the beginning every new season.||They form over water, move in a northern direction and usually hook in an eastern or western direction. They form in warmer water and dissipate in cooler water. I believe the warmer water allows for more evaporation, the winds carry the rain forming clouds toward cooler air. This causes storms to form and with this wind speed is increased. The streams of air press the storms into a counterclockwise rotation until the center becomes so dense it creates a downdraft. This keeps the storm strong and assists in the direction it is carried. As the storms continue to grow and travel, their destination is determined by water temperature and other storms around the planet as those other storms will cause the winds to change, therefore either increasing or decreasing the size and strength of any hurricane.||Hurricanes occur when certain conditions are met. As the storms gown, their conditions change and develop. They form over a period of days. The reason for their forming is the conditions of water, temperature and wind. They grow over a period of days because they do not form where they are strongest, but travel to the destination where they can become stronger. They dissipate when all the strength, conditions and supply of energy they obtained along their path is expelled or used up.||Based on the way the air travels, they are forced to spin in a counterclockwise direction.||The risk of hurricanes is greatest in the Caribbean. I believe it is due to the approximate location near the equator where the warmest of waters occur, the humidity is greatest and the opposing wind streams meet with a mixture of warm and cool that has the potential to cause the storms.||A hurricane's strength is based on windspeed. The lower the number the slower the windspeed. When it initially forms it begins at a 1 and moves on to a 2, but can quickly turn into a 4 or 5 over open water. As it passes by islands or larger land masses, it can drop to a 3 or lower if the conditions change, because the air pressure goes up as the down draft hits solid mass. As the storm moves back over open water it once again has the possibility of increasing to a 4 or 5.||As the air pressure goes up the windspeed goes down and vice a versa. The reasons I believe this works as it does is due to the force in the center of the eye. If the air pressure is strong enough it can cause the hurricane to stall and therefore cause the windspeed to diminish. As the air pressure in the center lessons, the windspeed can increase and the hurricane can once again move along its path.|
|10/29/2013 12:10:44||Ashley Burton||Hurricanes are named evenly male and female. I believe that those who name them start with the first letter of the alphabet and go through the alphabet from there. Some names are retired if they are really terrible and cause massive destruction.||The origin of hurricanes usually begins over a point in the ocean and then it spins in a clockwise motion over the body of water, typically gaining speed over the water due to the wind and temperature and pressure. Upon making landfall hurricanes will hook inward sharply and then decrease in speed as they make their way on land.||Hurricanes usually start forming during the late summer early autumn due to the cold air temperature and the warm air from the ocean meeting. The two meet in the middle and begin to form the spiral that is a hurricane||Hurricanes spin in a counter clockwise direction. I would assume that it's due to the direction of the wind and the rotation of the winds.||The area at which there is a greater risk of hurricanes is the south eastern part of the US and the Caribbean Islands due to the warm temperatures of the ocean and the coolness of the air. Especially Florida and the Islands.||Hurricanes are most likely to be higher category when it has access to the warm ocean air and the cooler air above. When it hits land the strength of the hurricane decreases due to the fact that the hurricane no longer has access to the ocean air.||As the pressure goes up the windspeed goes down and the opposite is the same. As the pressure decreases the air gets pulled down so it raises in speed.|
|10/29/2013 15:07:56||Randy Daniels||Names are chosen alphabetically...majority of them are named after women.||Hurricanes are formed over water. They travel in large, circular, clockwise patterns.||Most hurricanes occur during the fall when the Mid-Atlantic and NW Atlantic regions have cooled. I don't have a hypothesis for this.||Counterclockwise. The directional rotation of the Earth.||Along the Eastern and Western Atlantic Coasts.||It is mostly likely to be a high category while it is over water. Hurricane strength and speed decreases over land because there is more friction to overcome (?).||Inversely proportional to each other.|
|10/29/2013 21:10:48||Sheri L. Delkhah||http://geology.com/hurricanes/hurricane-names.shtml|
As of 1979, for each year, a list of 21 names, each starting with a different letter of the alphabet was developed and arranged in alphabetical order (names beginning with the letters Q, U, X, Y and Z were not used). The first tropical storm of the year was given the name beginning with the letter "A", the second with the letter "B" and so on through the alphabet. During even-numbered years, men's names were given to the odd-numbered storms and during odd-numbered years, women's names were given to odd-numbered storms (see the table above for recent name lists).
|It seems that they all start at the north of the equator. The clockwise rotation (in the Northern Hemisphere) of air associated with high-pressure systems often cause hurricanes to stray from their initially east-to-west movement and curve northward.||It usually forms in summer and fall when temperature reaches the high of 82 in tropical area. As a result, tropical rains are formed and when high wind and rain are met a hurricane is born.||Based on the direction that the wind travel which is seems to be counter clock wise and it creates like a spinning roll.||South eastern part of U.S.A, because of the warm temperature in the ocean and the cool weather out side. All the state close to the ocean have a greater risk ( such as Florida)||It is much stronger before it lands. The speed of the wind lowers when it hits the land.Hurricane Isabel looses much of the speed when it hits Atalanta, Philadelphia, and Detroit.||The air pressure starts high but it goes down as soon as the wind speed goes higher. They go opposite, when the air pressure is high the wind speed is low, and when the air pressure goes down the wind speed increases.|
|10/29/2013 22:41:57||Sarah Ishida||They are named in alphabetical order||Most originate in the north or mid-Atlantic ocean in August and September. They move west toward North and Central America as they speed up. When they hit land, they slow down as they turn clockwise, until they break apart. Heated water that evaporates and rises is what contributes to the depression and eventually the hurricane. As it moves west, the water is most likely warmer because it becomes more shallow which heats up more than pelagic waters. The hurricane continues to gain momentum until it hits land and there are no more rising moist air to contribute to the hurricane so it eventually dies out.||I believe that by the end of summer the oceans and atmosphere are the warmest. Warm water is evaporating and rising the most during this season.||Counterclockwise. Just like water goes down the drain in the same direction every time, the Coriolis effect causes winds to deflect in that direction.||Right along the east coast, because hurricane speeds are the highest then. As soon as it comes inland, the hurricane begins to slow down.||Most are category 4 and 5 by the time they hit the coast. When they hit land, they will begin to slow down and lower in category number.||I'm not sure but...an object in motion will remain in motion and travel at the same velocity as long as no force is exerted on the object. So when there is less pressure on the hurricane, it is not slowed down and will only speed up because of the added winds from rising heat.|

Strength of hurricane decreases as it hits land
|As pressure drops it allows the windspeed to increase, allowing the eye wall to achieve greater heights|
|10/30/2013 15:56:25||Kathy Gumber||I did not notice a pattern.||Hurricanes originate in the atlantic where warm, moist air (>85 degrees) rises and forms a tropical depression (collection of storm clouds). If this depression is allowed to grow wind speeds increase to tropical storm speeds >39 mph or can increase to hurricane speeds (75+ mph). These storms travel east to west gaining speed and strength as they travel over open water. This energy is expended when they travel over land or as conditions over water that encourage hurricane formation diminish. The east to west travel in the northern hemisphere is probably due to the rotation of the earth.||hurricanes occur in the fall when water temperatures tend to be warmer than air temperatures.||Hurricanes spin counter clock wise, probably due to the rotation of the earth||The storm surge (unusually high and tides and strong surge) causes most of the damage to property and life when the storm reaches land fall. This is due to flooding, and the health hazards related to flooding such as drowning, downed power lines and lack of power and utilities and resulting increased hazard from lack of potable water and exposure to disease.||Hurricanes reach their greatest strength as they move over shallower water right before landfall. The hurricane is more likely to be a category 1 or 2 over open water with the category number increasing as the hurricane moves toward land. Once the hurricane makes landfall the strength begins to diminish.||As air pressure drops, wind speed increases. The low pressure allows for the in rush of warmer air from outside the low pressure area and this increases wind speed.|
|10/31/2013 17:26:06||Curtis Ward||Almost twice the number of male names then female names.||Mitch appeared to wonder off the North shore of Columbia North then west then south through Honduras and then as is travelled higher in the latitudes picked up a predictable course north eastern out of the Yucatan peninsula through the Gulf across central Florida, actually picking up wind speed 5 mph, crossing Florida and exiting to the east past Jupiter Florida and traveling North over water up the western Atlantic into the Northern Atlantic. Following traditional wind patterns. I think where it started in the Southwestern Atlantic close to the equator the prevailing winds were not as dominant.||The Hurricanes like Mitch and others occur during a specific time of year. From late Summer to Mid Fall. I think that has something to do with the change in seasonal weather patterns and temp.||Almost all have a counterclockwise direction. The rotation of the earth causes the wind to flow from west to east and as the low forms begins to suck wind down and the rotation is established.||Hurricanes can occur when ocean temperatures warm and the water begins to evaporate causing cumulunimbus clouds to form rapidly this allows for the rapidly forming thunder head to reach great altitudes. As the cloud rises it cools rapidly to cause the air to sink and as the travels over the water creating a cooling effect like a swamp cooler begins to feed itself. Greatest areas appear to be Eastern Atlantic off the coast of west Africa or South Pacific moving North. As they Form near the equator they travel northwest and pick up the air flow pulling them over Japan , Mexico, Gulf States in the US(Louisiana, Texas, and Florida Especially).||Hurricanes appear to by the strongest out in the open ocean no land obstructions which would account for the winds slowing over land.||As pressure decreases the wind increases. Like a flushing toilet the syphon action caused by the low pressure in the middle pulls faster.|
|11/2/2013 13:19:22||Christian Gori||Names are male and female. They appear to alternate. Additionally, names proceed through letters of the alphabet. One name will be Adam, the next Bertha, and so on.||Hurricane formation begins around the equator, in the Atlantic and Caribbean. Once on land, Hurricanes tend to hook.||Hurricanes form in the summer and fall when temperatures are high. The warm temperatures fuel the storms' formation.||Hurricane's spin counterclockwise as a result of the Coriolis effect.||The Eastern and Southeastern US are particularly prone to hurricanes. Warm waters and temperatures tend to exacerbate the problem.||Hurricanes pick up strength over water and then lose that strength as they hit land.||As the central pressure decreases, the winds normally increase.|
|11/2/2013 17:38:19||Tony Guerrero||Hurricanes have beginning and ends to seasons. Hurricanes are named alphabetically starting with the letter A. Also, each year they alternate the starting name gender (i.e. odd years are female names and even years are male names). I believe the names are predetermined before each season.||Many hurricanes seem to originate in the Northwest region of the Atlantic near the Carribean islands and Mexico. There is a trend for them to move from south to west and although they spin in a counter clockwise direction, they travel in a clockwise direction. I believe the reason for this is due to the cold air from the north coming down and being forced upwards by the stronger hot air from the south.||Hurricanes almost exclusively happen in the month of September. This could be caused by this being hottest month of the season typically in that region.||Hurricanes appear to spin in a counter-clockwise fashion. My theory for this is that the cold air above is traveling in one direction when it hits the hot air that is is flowing in the opposite direction causing the wind direction to be counter-clockwise.||The greatest risk of hurricanes is when they hit land. At sea level where the ocean meets land, violent and turbulent ocean waves can cause great amount damage to life and property.||Hurricanes build strength generally over time and over the ocean. This is when Cat 5 hurricanes typically get recorded.||Higher pressure increases the energy of the hurricane producing greater windspeed.|
|11/3/2013 10:05:26||Garry Joseph||Looks like names are alphabetically ordered and alternate between male and female. Every year it gets harder to name a baby without associating it with a hurricane. I understand the need to name the event but why anthropormise it?||Most start near the equator over the sea. They travel over the sea towards the east coast of the USA.||They seem to concentrate in the late summer months, as if there is a "hurricane season".||Hurricanes appear to spin counterclockwise. This direction might be initiated by the rotation of the Earth.||Anywhere near the coast of the USA, especially Florida, getting the brunt of the windspeed acceleration.||The hurricane loses energy as it spreads over land. The category decreases as the hurricane travels over land.||They seem to be inversely proportional. As one increases the other one decreases, which may be demonstrable in a lab activity.|
|11/3/2013 15:08:01||George Burdo||Most names are female (but male names weren't used until 1979, then they started alternating).||Hazel started in the warmer waters off the coast of Venezuela, moved up through the Caribbean picking speed before making landfall near the South Carolina / North Carolina border. From there it moved fairly straight north, before turning east. The movement possibly followed the warmer waters. Once hitting land, possibly prevailing winds kept it on a straight track until the northern latitudes were obtained and then it started east, creating a somewhat anticlockwise hook.||The start of Hazel was early October, during a time of year with shifting temperature. The heat of the warmer waters, and cooler air, could possibly cause a energy shift between the two mediums giving rise to a storm.||Anticlockwise - I believe due to Coriolis effect of the earth's rotation.||Based upon the NOAA map, the Gulf coast appear to be the largest landing location. It would appear that the majority move in an westerly direction, with a minor to major anticlockwise hook or turn which would lead to many hitting this region since it it also warmer water than the eastern seaboard which generally does not support the creation / continuation of hurricanes.||From the formation of tropical storms, the strength builds. As it crosses into warmer water, air speed increases. In the shallow waters near a coast, the water is likely to be warmer than the deep water areas, thus providing more energy to the storm. This makes the storm often at it's peak at landfall. Landfall also cuts the storm off from its major source of energy, and then the strength declines as it moves inland, away from its former heat source.||Limited data: only three pressure points were available and no correlation was noted. The highest pressure point (994 mb) had the medium speed (85 kts), the lowest pressure point (937 mb) had the highest speed (110 kts), and the middle presure point (970 mb) had the lowest speed (80 kts).|
|11/3/2013 17:02:03||Mary Wrobleski||Names are assigned in alphabetical order. Names can be reused but it seems like a minimum number of years must elapse before a name is reused.||Hurricanes begin in tropical or subtropical waters because the ocean water needs to be very warm. The direction of the hurricane is influenced by winds- Hurricane Frances, for example, originated in the mid-Atlantic and made landfall in south Florida, "pushed" by the tropical easterlies.||After the sun has heated vast stretches of ocean water in the summer and fall to over 82 degrees, warm moist air rises over these hot spots creating thunderstorms. Upper level winds and surface winds come together forming a circular pattern called a tropical depression.||Hurricanes in the northern hemisphere spin in a counterclockwise rotation while those in the southern hemisphere spin in a clockwise motion due to the Coriolis Effect .||Hurricane risk seems to be greatest when the hurricane makes landfall. The resultant storm surge is accompanied by heavy rain, flooding, and high winds; potentially causing loss of life and severe damage to coastal communities.To a lesser extent, inland communities can also experience flooding from heavy rain and damage from high winds.||Hurricanes begin as a tropical depression, with sustained winds at 25 mph. With showers, thunderstorm activity and winds that hit 39 mph, the tropical depression becomes a tropical storm. As the winds increase to 74 mph and the closed circulation system becomes an eye, a category 1 hurricane is "born", according to the Saffir-Simpson Scale. Category 2 is winds between 96 and 110 mph; category 3 is winds between 111 and 129 mph; category 4 is winds between 130 and 156 mph; category 5 is winds of 157 mph or more. A hurricane is most likely to be stronger over water. The strength diminishes upon landfall in most cases.||Air pressure and windspeed are inversely proportional.|
When warm, low-pressure air rises in the storm, cool high-pressure air moves in underneath it. High-pressure air over the storm's center removes heat from the rising air. As high-pressure air is sucked into the low-pressure center of the storm, wind speeds increase.
|11/4/2013 7:02:34||Mark Yaney||they seem to alternate between male and female names||ORIGIN|
Hurricanes seem to originate where the water is warmest, and once enough ariflow movement is established, they seek move movement of warm air
Once the morphology of a large depression forms, it continues to seek out more warm water, following sea currents to get there
PATTERN OF MOVEMENT
|Hurricanes occur in the summer months in the northern hemisphere when the waters of the North Atlantic are at their warmest||hurricanes are low pressure systems which spin anticlockwise in the northern hemisphere due to the coriolis effect. The same phenomenon occurs in the southern hemisphere, and lows spin clockwise.||Hurricanes seem to follow the path of the gulf stream, right up the eastern sea board of the US. The gulf stream is a roadway of warm sea water. It's like a rail.||Hurricanes diminish and die over land as they lose fuel -- warm water. They seem to become strongest when they exist in areas of largest gradients, i.e. warm water next to cooler land.||As the air pressure drops, the windspeed increases. Massive air from the atmosphere falls down into the depression and accelerates. The deeper the depression, the more acceleration, and the higher the windspeed.|
|11/4/2013 17:49:40||Mallory Gallagher||Equal distribution of male and female names.||Hurricanes tend to originate either in the Caribbean near Mexico or Cape Verde Islands & West Africa. These places are the perfect area for warm moist air to gather, creating storms allowing winds to come together and form hurricanes.|
Most hurricanes move clockwise preferring to follow the warm water to pick speed and strength. This is most likely because when they hit land they tend to loose their strength so it makes sense for them to occur and continue over the warm Atlantic or Gulf of Mexico waters.
|The hurricanes happen in the months of August - November. These months give time for the ocean water to warm and create hot moist atmospheres for the hurricanes to occur.||Counterclockwise. Potential explanations: natural wind patterns, influenced by the earths rotation.||Risk for hurricanes is greatest along the states that share a shore with the Gulf of Mexico. When the hurricanes start near West Africa or in the Caribbean they are given time to develop. Most hurricanes seem to have a clockwise hook at the end of their run putting the states that boarder the Gulf in particular danger. The storm is fully developed, the Gulf provides ample warmth in the water to feed the hurricane, and the pathway near the end of the hurricanes life hooks just so it turns into the Gulf coast states.||Hurricane strength increases over sea, most likely due to the warm waters fueling it and decrease over land. In the beginning and the end is when it will be a category 1 or 2 however hurricanes can decrease in strength midway through keeping the category at a 2. Once it gains more strength and is refueled by warm seas it can grow again to its full potential of category 3 - 5 ranking.||Pressure and windspeed are mostly inversely proportional. When the pressure goes down it leaves less resistance for the wind and vice versa.|
|11/5/2013 19:35:51||Matthew Duda||They are alphebetical. They seem like just random names are chosen with a specifc first letter.||Most of them appear to start over the sea and above the equator. They seem to travel towards the US. Once they get towrads the land they start to move in a counterclockwise movement.||Most of them start in august and September. This may happen because of the changes in temperature and the water temperature.||Most of them appear tp spin counterclockwise. I believe they spin this direction because of the rotation of the earth.||The risk of huuricanes is gratest near the coast. It seems as the strength of the hurricane rises as it gets closer to land. It picks up speed over the ocean and when it hits the land it starts to slow down.||It is most likely to be a category 5 when it has time to pick up speed over the ocean. Once it hits the land it quickly changes to a lower category.||For most of the hurricanes air pressure and windspeed are inversely proportional. As one goes up the other goes down. Since the wind speed in rising the movement in the air lowers the pressure.|
|11/5/2013 19:41:01||Kyle Tacsik||It appears that hurricanes are named by either masculine or feminine names, and these names alternate as they work through the alphabet.||Hurricanes tend to originate in the eastern or southern parts of the Atlantic Ocena but north of the equator. The hurricanes tends to hook in a clockwise direction after they reach landfall in the United States. This may have to do with changing wind patterns at higher latitudes, or, perhaps it has something do with physics in the sense that for each action there is an equal and opposite reaction, so, when the hurricane spins counter-clockwise, this affects it so that it hooks in a clockwise direction overall.||The typical timing of hurricanes during the months of July, August, and September probably relates to the rotational orbit of the Earth around the sun. Surely, during this time, some events must be coming together to create hurricanes.||Hurricanes appear to spin in a counter-clockwise direction. This may be due to the wind patterns that exist North of the equator. Perhaps winds blow east to west, thus generating the counter-clockwise direction of the spin.||Hurricanes tend to most commonly strike the south eastern part of the United States, commonly Florida or the states bordering the Gulf of Mexico. As Hurricanes move up through the Caribbean toward the U.S. these states are at the greatest risk because wind speed does not slow down until the hurricane strikes land, so border cities and towns would feel the brunt of the impact of a hurricane. Also, islands in the Caribbean are also at great risk.||Hurricanes tend to be of greater strength when they are over the ocean, once they hit land they tend to decrease in strength quite quickly until they eventually fizzle out.||Pressure and wind speed maintain an inverse relationship. I don't feel like I know enough about the fundamentals of windspeed and air pressure to provide a hypothesis on why this would be, I might need some refreshing on these ideas first or review.|
|11/6/2013 0:16:41||suravi choudhary||Male and female hurricanes alternating||origin mostly in the caribean sea near mexico, high speed over the ocean||Mostly during september.||mostly counter clockwise due to Coriolis force.||Florida.||Category 5.|
When the hurricane hit the land its strength decreases.
|Pressure and speed are inversely proportional.|
|11/6/2013 14:22:18||Jorge Encinas||Names alternate between male and female||Most hurricanes appear to make a clockwise hook trajectory which might have to do with the NE Hadley trade winds direction markings on the surface of the earth.||Fall and Spring. |
Hypothesis: There is greater chance for the air to change temperature, creating a low pressure and high pressure points in the atmosphere.
|Most of them seem to spin counterclockwise. Looks like some information on the web indicates that it is because the equator moves faster than the tropics.||The areas where the hurricanes occur the greatest would be in the tropics. |
The tropical areas are where there is the most change in wind speed and temperature change which in turn favor the spiraling movement of air in the ocean.
|The pattern of hurricane strength: It's strength is the greatest when it is in at sea. The winds move faster in the ocen than in land.||Air pressure and windspeed are inversely proportional. As one goes up, the other goes down.|
Potential explanation: The energy of the hurricane is somehow preserved but part of it is used to maintain windspeed while the other part of the total energy maintains pressure. If more energy is needed for one task then the other task is slowed down.
|11/7/2013 10:43:15||Gerardo||Used to be just female names back in the day. They changed it to alternate male and female names.||From what i saw in the data, hurricane seems to come from Carribean near Mexico as is in the case of my hurricane Stan.||Summer and fall. During these times, the oceans are the warmest due to the heat of the sun and its what causes the warm air that go up. Eventually, it forms into a low pressure system that causes hurricanes later.||Hurricanes move counterclockwise it seems.||Since hurricanes originate usually in the Carribean and Mexico, Florida is usually the state most susceptible to danger of getting hit by it. So, when hurricanes reach Florida, it receives the most force from the hurricane and subsides as it travels along the land.||Because most water come from the ocean, hurricane strength is strongest in a large bodies of water. It weakens as it travels over land due to lack of enough bodies of water to sustain its strength.||Inversely proportional.|
|11/9/2013 3:52:57||Chris McLemore||Hurricanes appear in the Atlantic Oceans in the late summer and earily fall months. They seem to route counter-clockwise and track in a clockwise path around the Atlantic. Most seem to have more power over the water and lose power over land.||They seem to follow a clock wise path around the atlantic. May be due to wind patterns.||Early fall months, change in weather patterns due to seasons.||They appear to spin in a counter clockwise motion.||Eastern coast of USA.||over land the storm loses power.||As pressure drops wind pick up and vice versa.|
|11/11/2013 14:14:26||Jasson Przebieda||All hurricanes were named after women up until 1979 when a hurricane was named David. At this point it seems to be pretty random when selecting names for hurricanes.||By looking at the class data, we can see that most of the hurricanes have originated in the Caribbean near Mexico and the middle of the Atlantic. The destination is westernly toward the U.S. and Gulf (Central America). Although the hurricane spins counterclockwise, the movement pattern is in a clockwise motion.||Most of the hurricanes appear to form in August or September, which are the warmest months in the Atlantic. As the water temperature rises, the chances for tropical storms and hurricanes increase rapidly.||They spin in a counterclockwise rotation. Hurricanes rotate this way because of the earth's rotation on it's own axis.||The higher risk areas exist in Florida and Lousiana. This may be because the hurricane's movement clockwise, driving it into the U.S. at these areas first.||Hurricane strength is at it's peak (closest to category 5) as it gets closer to the land. This is most likely because the hurricane has had the most time to accumulate momentum and speed. As the hurricane hits the land, the strength decreases as the hurricane loses momentum caused by friction on the land.||Air pressure and windspeed are inversely proportional. As the windspeed increses, the air pressure decreases and vise versa.|
|11/12/2013 19:06:01||Richard Hanley||Male & female names. No real pattern outside of alphabetical.||The path of hurricanes are usually clockwise from their origin to termination. Spin a top counterclockwise & it takes a clockwise path.||Hurricanes form from June to November. The peak seems to be in Aug/Sept. Odd that Haiyan, the most powerful typhoon on record, occurred so late in the season.||Counterclockwise. Denotes falling, low pressure, air. Global winds, from the picture of the Hadley cell, move west from 0-30 degrees N & east from 30-60 degrees north - where hurricanes develop - which would cause the opposing effect on the winds (i.e. clockwise moving winds would cause counterclockwise moving cyclones).||Eastern seaboard of the U.S. from Virginia to Texas and the islands between the eastern Atlantic and western (worse as you get close to the U.S. like the Caribbean islands). Though odd that the Philippines & Vietnam would be so affected by Haiyan.||Category 5, near the Caribbean, in Aug/Sept. Upon hitting landfall, the storm dissipates and terminates.||Counterclockwise windspeed causes low pressure. When pressure increases, windspeed would decrease.|
|11/17/2013 22:56:30||Anna Tavitian||The only pattern I noticed is that they are male or female names.||In the northern hemisphere, the hurricane's originate over the ocean near equator and then move northwest then east; the combination wind patterns, earth's rotation, and its spin cause the hurricane to movement.||August & September.Due to summer time, warm ocean water, which may cause a convection to occur.||Due to their location, most of the hurricanes are moving clockwise, because they are in the Southern hemisphere. In the Northern hemisphere, they move counterclockwise. Which both are due to Earth's rotation.||Near Florida and Texas||Based on their speed, each hurricane is place in category. In category 1 hurricanes move at a speed of 74-95mph, where as in category 5 they move at a speed of 156 or greater mph. As the hurricane hits land, it strength decreases.||They are inversely proportional. The air pressure increases as windspeed decreases and visa versa.|
|11/18/2013 17:18:11||Dave Green||Alternating Male/Female||Origin of Hurricanes in Atlantic north of the Equator. Destination North and Central American continent, Gulf of Mexico and Northern Atlantic. Hurricanes move westward, north westward, and occasionally North as they expend their energy.|
This movement may be due to Coriolis effect and interactions between surface winds and upper level winds.
|Hurricanes occur mostly in August and September after the oceans have heated up over the Northern Hemisphere summer. This energy is stored in the oceans and causes more evaporation, putting more heat energy into the atmosphere and causing more thunderstorms.||CounterClockwise due to coriolis effect||Risk of hurricanes is the greatest between 15 and 30 degrees north and south latitudes, this is the area that would have the right combination between high ocean temperatures to provide the energy for the storm and surface and upper level winds that would provide the rotation - I think!||Hurricanes start out as tropical depressions, build strength as they gain energy from warm ocean water. Would then move up the scale as long as energy is being absorbed from warm water... 1 - 2 - 3 - 4 - 5 It would most likely be a 5 over open water as it is about to reach landfall. It's strength would diminish as it moves farther in land since its energy source is cut off.||An inversely proportional relationship, as air pressure decreases you have a large pressure differential that causes the atmosphere to try and equalize this difference. Winds blow hardest because of this difference in pressure between the low pressure system - hurricane, and the surrounding high pressure systems.|
|11/18/2013 19:19:16||Marsch A. Fazio||The names appear to begin with the first letter of the alphabet each year and then go through the letters as new storms arise. THe male female names also seem to alternate.||Hurricanes appear to vear off in the direction of their spin. but once they hit land as the winds slow they appear to turn toward the opposite direction||Hurricanes appear to begin in the summer through early fall. This seems to be when their is the greatest difference between atmospheric temperature and sea surface temperature.||Counterclockwise. I belive this is due to the Coriolis effect. The Earth rotates counterclockwise and causes winds to appear to curve.The low pressure system at the middle of the hurricane pulls the higer pressure on the outside toward the middle also.||Eastern United States, SPecifically south near the Carribean and gulf of Mexico||Hurricanes seem to at their greatest force just before landfall, when they do hit land they tend to slow down. Maybe because their is less of a difference in temperature between land and air?||It is inversely proportional. warm air is rising and cool air is replacing it. When the air pressure is low at the center air rushes in quicker (higher wind speed) for High to low pressure|
|11/19/2013 18:53:49||Ana Melkumyan||Gender is half and half between male and female||According to the table, most of hurricanes originate in Caribbean near Mexico.

I am afraid to mistaken my hypothesis||according to the table most of hurricanes appear to spin clockwise||According the table, most likely to be category 1. I think based on my observation of the hurricanes tools, once the hurricane hits the land its strength decreases. The strength decreases as a category increases.||I see that air pressure and windspeed are inversely proportional. As one goes up, the other goes down|
|11/25/2013 17:16:09||Mary Ann Dortch||Hurricanes have first names of males or females. They are named in alphabetical order, with the first one of the year starting with an A, the second starting with B, and so on. The names may be repeated after 5-6 years. Some names are not repeated, because they have been so destructive. Every other one is a boy or a girl's name, beginning with female.||It appears that most hurricanes originate in the NE Atlantic Ocean. This is where the sun heats directly making the water temperature higher. The hurricanes move northwest. Most hit Florida or Louisiana first.||Northern hemisphere hurricanes appear to have a "season" which is mostly from August - November. The ocean water is probably warmest then.||Hurricanes appear to spin counterclockwise, possibly because of the Earth's rotation and the Coriolis effect.||Hurricanes like to strike in South Florida the most, and in the areas of the Gulf Coast, especially in Louisiana. Many hurricanes also hit the East Coast, from Florida up the coast of the United States. States near these are often affected.||Hurricanes build up strength over warm ocean water. They are likely to be high strength when they build up over the ocean near the coast. As they move over land they lose their power and lessen in intensity.||Air pressure seems to depend on wind speed. They appear to be inversely proportional from the graph.|
|11/26/2013 18:38:20||Jesus Ojeda||I noticed that the hurricane I chose occurred previous years ago as well and I saw no correlation between having male names and female names.||The hurricane started in the Atlantic Ocean and started traveling north west until it hit land and then started traveling north east. The winds probably have a pre determined route that influences the path of the hurricane.||The hurricane occurred in the month of August.||The hurricane I chose did a clock wise motion. Once the hurricane hit land, the speed of the hurricane decreased from when it was in the water. When Katrina was on land, it made a hook motion that seemed to move counter clock wise.||There is greater risk of hurricanes in the Atlantic Coast and the Eastern part of the United States. The states in the south of the United States are the most susceptible in having hurricanes.||Level 1 is categorized as low speed winds while level 5 hurricanes are extremely fast and destructive. When hurricanes hit land, the speed of the hurricane usually decreases. The speed of the winds determine what level hurricane it is.||Air pressure and wind speed are inversely proportional. When air pressure decreases, the wind speed increases and the other way around.|
|11/27/2013 11:42:22||anna mkrtchyan||Hurricanes names switch back and forth between male and female names. Sometimes names are repeated in different years.||Most hurricanes start on north of the Equator and move towards to North West.||Hurricane mostly occur in August and September, because water is warm that time.||Hurricanes appear to spin in counterclockwise direction. It could be due to Coriolis force and Earth's spin.||The greatest risk of hurricanes is in Florida and on the gulf and south eastern coast of the US, where hurricanes first hit land.||Hurricanes are categorized by their wind speed. A category 1 has wind speeds of 74-95 mph, category 2 has 96-110 mph winds, category 3 has 111-130 mph winds, category 4 has 131-155 mph winds, and a category 5 has winds greater or equal to 156 mph. We observed that most hurricanes decreased in strength as they hit land. This is due to the friction and because it is no longer over the warm ocean water that it needs for energy.||The relationship between air pressure and wind speed is an inverse relationship. Decreased air pressure creates a downward effect, pulling the air down increasing the speed.|
|11/27/2013 23:42:38||Megan Whitaker||There seems to be an almost 50/50 split on naming hurricanes with either male or female names.||Most of the hurricanes originate in the Atlantic and Caribbean, near either the West Coast of Africa or near the coast of Mexico. The hurricanes move in a north westerly direction, heading towards the Northern part of Mexico and the Southeastern United States.||The majority of hurricanes occur during the Autumn season between August and November. This could be due to the changing of seasons, where the warmer weather in the southern hemisphere is being pushed northward and is meeting the cooler air in the northern hemisphere.||The majority of hurricanes appear to spin in a counterclockwise direction. This could be due to the convection currents in the air that draw cooler air south and push warmer air north.||The risk of hurricanes is greatest in the American Southeast, the islands of the Caribbean, and the Eastern coast of Mexico. Hurricanes appear to make landfall in this part of the world most often and often the hurricane will strike multiple places along the Eastern seaboard. Some of the hurricanes travel as far north as the coast of New Jersey and Massachusetts.||Hurricanes start off as tropical depressions over the Atlantic. The grow in strength as they move west and north across the Atlantic. They pick up speed and are classified as category 1 or 2. The farther north and west it goes over the ocean, the stronger the hurricane gets. It seems to get to category 3, 4, and 5 as it is approaching land. Once it is over the land, it slows down and is again classified as a tropical storm.||As the windspeed increases, the air pressure decreases. I think this causes the hurricane to spread out and start to break apart. When the pressure is high, the hurricane's windspeed drops and the storm sort of slows down or stops moving over an area. The wind is less, but the storm clouds appear to be more solid.|
|11/28/2013 4:39:09||Brooke Colley||The naming of hurricanes is male and female names alternating. The names are predetermined and rotated every 6 years.||Close to equator in warm moist surface water temperatures, and equatorial winds converging. Hurricanes appear to move in a clockwise direction. The origin is general in the Caribbean region and most take land over florida.|
This movement occurs due to the Coriolis force.
|Hurricanes occur in warm moist air - general in August based on our class data but can be from june to november.|
As soon as they travel over land or cooler waters , they loss access to the warm moist air of the oceans that fuels their intensity and they then tend to dissipate
|A hurricane appears to spin in a counter-clockwise direction in the northern hemisphere. In the southern hemisphere clockwise. |
The spin occurs due to convection type currents - warm air rises, cooler air rushes underneath, incoming wind draws in moisture, condensing to create more cloud activity
|Closer to the equator - Due to temperature during summer, warm moist ocean and winds||Hurricanes gain strength over warm moist oceans and will can be gain as high as category 5. As the hurricane moves over land the category decreases until it dissipates||Air pressure is inversely proportional to wind speed.|
Close to the eye wind speed rise and pressure decrease.

|11/30/2013 20:11:32||Elba c. Lopez||there is an even distribution between female and male names.||Hurricanes seem to start over the sea and continue on land moving toward the eastern states. A hypothesis that might explain this is that they are following a high pressure system.||Based on the data, hurricanes happen predominantly during the months of August-October. This probably is due to the amount of evaporation that has happened in the previous months.||The hurricanes move clockwise based on the pattern of winds||Based on the data, Texas, Louisiana and Florida are the high risk states. This is possible because since they originate near Mexico, and they share a coastal shoreline.||It is most likely to be a category 5 when it originates in the Caribbean. The strength diminishes as the hurricane hits land.||The relationship is that if there is a huge difference in pressure, the results will be high winds and vice versa. air flows from an area of high pressure to low pressure creating high winds.|
|12/2/2013 19:16:02||Denise Randol||Names are alphabetical and alternate male and female||Hurricanes in North America, start over warm water in Atlantic Ocean, some as far away as West coast of Africa. Some start north of Venezuela. Water is very warm and trade winds start tropical storms that evolve into hurricanes.||Hurricanes start around June and go until November because the Atlantic Ocean is very warm.||In the northern hemisphere they spin counterclockwise due to the coriolis effect.||The risk is greatest on the east coast of North America, the Gulf Coast, the Gulf of Mexico and the Caribbean Sea. The water is very warm, the air temperature is warm and its very humid. The gulf stream feeds warm water up from the equator and differences in air masses create instability.||Hurricanes are most likely to be strongest over the ocean. They lose energy over land, but can move back out to the ocean and pick up speed again.||As the air pressure drops, the windspeed increases. The lower pressure allows for increase movement of air particles.|

This could be due to the movement of the currents, winds and the warm water temperatures.||Most hurricanes seem to happen in July, August and September. This could be because the water temperatures are the warmest during these months.||Counterclockwise||In the US, the areas with the greatest risk are in the Southeast coast (Florida, Carolinas). As global warming continues coastal areas of Virginia, NJ, NY become more at risk. The coastal areas are at the greatest risk because the hurricanes lose momentum as they travel over land.||Hurricanes seem to start off weak, then pick up strength. It is most likely to be a category 3, 4 or 5 when it is over water. Once the hurricane makes landfall, the hurricane weakens and is more likely to drop to a 2 or 1.||Pressure and wind speed are inversely proportional.|

|12/7/2013 14:41:59||Wendy Banner||Based on entire class data as of December 7th, exactly half, (36) of the hurricanes chosen by my classmates,(beta cohorts) were given female names. Some hurricane were used multiple times as the number if entries exceeded the available number of hurricanes. The first male name occurs in 1979. This is due to the earlier naming convention of using only female names. Only the more recent hurricanes have names beginning with letters past the middle of the alphabet. Mitch, and Zelda all fall after 1994, with Sandy, Stan, Wilma since 2005. Have there been more hurricanes or has reporting increased to use up the alphabet?||The funnel is coursed by the updraft of heated air over the warmed ocean water . The rising heated moist air drowns in similarly heated air from all directions in the Hadley Cell producing the spin (previous answer). As long as there is a supply of hot moist air the convection column is fed. Over land, the storm continues but slows down unless it can relocate over a warm enough body of water. |
As the storms initially travel west with the Trade Winds, they pick up speed and water over the warmer, shallower waters of the Caribbean /western middle Atlantic, (above the Equator).
|The seasonal timing of hurricanes is centered around September. |
The convection cell is driven by heat. If the oceans of the WEst African region of the NE Atlantic have reached their peak annual heat by late summer/ early fall , then there would be more hurricanes then.
|The hurricanes spin in a counterclockwise direction. Air nearer the equator is moving faster , (greater circumference for Earth's 24 hr rotation) displaying the Coriolis effect. In the Northern hemisphere, things end up to the right of where they were aimed.||The Gulf Coast is fairly risky, and so is the Eastern Sea Board. But FLORIDA catches hurricanes from both the south and the east. That state has the longest coast line, or the greatest interface with the source of risk - extending out into the sea as it does.||The greatest hurricane strength appears to be in and around the Caribbean waters, according to the NOAA tracking map. The ratio of red and purple lines compared to green and other category color looks the greatest there. That is a trapped body of relatively shallow water near enough to the equator to trap heat. Most of the category 4 and 5 hurricanes that actually hit land are on the Gulf Coast. ONce the tracks do cross land the windspeed category drops or changes to a tropical storm.||A pressure gradient will drive the wind speed. Lower pressure caused by for air will "pull" in the surrounding air faster.|
|12/11/2013 18:26:58||Jennifer Richard||Names are in alphabetical order and can be male or female.||Hurricanes appear to follow the direction of their spin. Their speed decrease once they make contact with land.||Hurricanes most frequently occur during the warmer months of the year (June through November). This may be due to more energy availability due to increased temperatures of the water during this time of the year.||Many hurricanes appear to originate in the Atlantic Ocean and have a clockwise spin. This is due to the Coriolis effect.||Southeastern United States.||Hurricanes are categorized by their wind speed. A category 1 has wind speeds of 74-95 mph, category 2 has 96-110 mph winds, category 3 has 111-130 mph winds, category 4 has 131-155 mph winds, and a category 5 has winds greater or equal to 156 mph. We observed that most hurricanes decreased in strength as they hit land. This is due to the friction and because it is no longer over the warm ocean water that it needs for energy.||I see that air pressure and windspeed are inversely proportional. As one goes up, the other goes down|

My hypothesis is that when the temperature changes for the season this causes a rise and drop in the winds and as wind fills the vacuum it causes a hurricane||They spin counter clockwise in the northern hemisphere||On the coast north of the origin of the hurricane because it swings up as it rotates clockwise on the northern hemisphere||They are their highest as they approach land because as they travel they gain speed but once they hit land they slow down||As the air pressure rises the air needs to fill the vacuum so the speed increases|
|12/19/2013 9:53:27||Riley Leary||Hurricanes seem to be names more for males than for females.||Hurricanes seem to originate in the Northern Atlantic ocean, spin counterclockwise and move clockwise. The wind speed drops when they hit land and they seem to spend less time overland than they do over the ocean.||Hurricanes seem to occur in late summer and fall. The changing temperature in the Northern Atlantic must have something to do with that.||Hurricanes appear to spin counterclockwise. This could be due to the direction the winds originate in the Northern Atlantic ocean.||The East Coast of the United States seem most affected in the lower portions like the Carolinas.||The highest category ratings seem to happen after the hurricane has been over water for a while, and drop when it hits land.||As air pressure increases, it seems the windspeed decreases, probably because the increase in air pressure makes it harder for the air molecules to move.|

|1/21/2014 13:01:15||Brie-anna Hope Rojas||In our data, the names were a 50/50 split between male and female. It could be that there is some alternating pattern in naming hurricanes based on this data.||Hurricanes always begin over water. When they occasionally hit land, they slow down (windspeed) and usually die out on land. This is because high humidity/moisture is required to fuel the hurricane and there is a greater temperature difference between air and water than between land and air. The difference in temperature creatures pressure differentials that also fuel the motion of the hurricane.||Hurricanes generally and usually occur between August and November with prime hurricane season falling in September. This is directly related to seasonal ocean temperatures. During these months, the water is very warm and which creates very humid conditions over the ocean. The warm air directly above the water rises and as it cools, it condenses to form clouds and rain around the eye of the hurricane (the area where warm air is rising and thus an area of low pressure).||Hurricanes primarily appeared to spin counterclockwise. This is likely due to the Coriolis effect wherein the earth's rotation affects the route of things (wind, air, water) traveling over long distances. In the Northern Hemisphere, the Coriolis effect produces a counterclockwise rotation of air and water.||Hurricanes are strongest over sea so the greatest risk is to those over sea during this time. However, even a category 3 hurricane can cause immense destruction on land. The eye of the hurricane will have the least amount of damage because that is the area of low pressure where warm air is rising - it is usually void of wind or rain and can be calm and deceiving because just outside of the eye is the greatest destruction potential.||Hurricanes gather the most strength (wind speed in particular) over sea where they are fueled by the humidity created from warm waters. By the time they hit land, they begin to lose speed and usually last less than an hour. It is most likely to reach the highest hurricane category 5 over sea and progressively weaken as it travels over land.||Air pressure and windspeed are inversely proportional to each other. This is because air travels from areas of high pressure to areas of low pressure therefore the highest wind speeds would be in regions of low pressure and vice versa.|
|1/21/2014 16:20:24||Randy Barsoum||They are in alphabetical order||They tend to begin near the west coast of Northern Africa and move towards the Eastern US. They begin with high pressure and low wind sped. The pattern is they heat up (gain energy) from the warm ocean waters, the pressure falls as wind speed picks up and then make landfall off the US Coast. As they move inland, they lose speed and pressure tends to increase.|
The possible reason for this movement is the very warm waters off the coast of Africa and less atmospheric resistance as it moves westward.
|They tend to occur during the fall and summer months possibly due to the warm waters.||counterclockwise. The counterclockwise rotation may be due to the upper level and surface wind patterns above the oceans.||On the south east coast and the Gulf of Mexico in the US. Texas, Mississippi, Alabama and Florida tend to get the most Hurricanes. This is likely due to the warm waters surrounding these states.||It tends to start as a Category 1 and increases in speed with a decrease in pressure as it moves over warmer waters. As it moves closer to the coast of the US, it tends to increase in Category (from 1 with a wind speed of 75+kts to 2,3,4 or even 5) as it moves over warmer water and does not encounter much resistance. It could be as big as a 5 when making landfall if it originates closer to the US coast (Gulf of Mexico rather than near Africa). This may be due to the fact that the hurricane doesn't lose strength over possibly cooler waters when making a long transit between Africa and the US. Since the Gulf waters is very warm then the hurricane can gain enough energy and make landfall rather quick.|
The hurricane tend to break apart and lose strength upon making landfall but not until causing devastation.
|They tend to be inversely proportional in the outer edges of the hurricane. As you move towards the eye, the pressure and wind speed tend to be proportional in that they both decrease. |
This may be due to the rotation speed and moisture within the hurricane.
|1/21/2014 18:45:49||Jason Elliott||According to the data in the table 51% of the hurricanes have male names and 49% have female names. The names appear to alternate between male and female. Names are used more than once.||A majority of the hurricanes began in the Caribbean near Mexico, but a large portion began in the NE Atlantic near the Cape Verde Islands. The hurricanes gain strength moving in a clockwise pattern towards landfall mostly in the Southern United States. Upon landfall the windspeed decreases.||Most of the hurricanes happened in the summer months of August, September and October. During the summer months, temperatures rise and air pressure increases.||85% show hurricanes spinning in a counterclockwise pattern. The Coriolis Effect is responsible for the direction of the spin.||Florida has the highest number of hurricanes making landfall. It has long Atlantic coast as well as a long Gulf Coast, so it can be hit by both sides.||Hurricanes gain strength as they travel over water. They are most likely to hit a Category 5 over water, since hurricanes generally lose strength once they make landfall.||Inversely proportional|
|1/21/2014 20:39:17||Daniel O'Brien||The names tend to alternate between male and female names with the first letter of each subsequent hurricane being the next in line in alphabetic order.||Hurricanes seem to all begin in the central/eastern Atlantic ocean in late summer/early fall. I would suspect that there is a correlation between ocean currents and temperatures with atmospheric currents and temperature. Also atmospheric humidity is likely a factor as well. These are areas for further research.||See "Movement" above||Hurricanes spin in a counter-clockwise fashion. My intuition is that it has to do with the Coriolis Effect, but I would want to research this further before I went around promoting this idea!||Obviously the areas of the continental US on the south eastern seaboard are most vulnerable to damage from hurricanes. This is because hurricanes most frequently form in the Atlantic ocean just east of these areas and almost always head west and north.||Hurricanes tend to build in force as they develop. Their wind speeds seem to universally drop when over land. Their force/energy appears to dissipate over land.||Air Pressure and windspeed are inversely proportional. I do not know why this is. High pressure seems to inhibit high wind velocities.|
|1/22/2014 8:04:14||Rebecca Falin||The names seem to alternate between male names and female names. Names are reused as many of the names in the database appear more than once with different years.||The hurricanes in our data list seem to originate either near Spain or northern African and counterclockwise across the Atlanta toward North America, or they orginated in the Carribean and arched toward the northern US or Gulf of Mexico. It may be the storm follows a low pressure zone.||Most of the hurricanes occurred in the late summer and early fall when the temperatures at the equator, near where the hurricanes originate, is the highest.||About 3/4 of the hurricanes studied spun counterclockwise. They also arose North of the equator. This is due to the Coriolis effect - the Earth spins faster at the equator than at places above the equator and the temperatures are higher at the equator than above.||Looking at the course data, the areas of greatest threat are Florida and Texas. Florida is the southernmost state on the East coast of the US and also borders the Gulf of Mexico and Texas is the largest in the Gulf of Mexico. Other Gulf of Mexico states also posted hits, including Mississippi and Louisiana. Less often hit were states further north along the East coast of the US.||Hurricane strength seems to increase over water with the highest values obtained over water, and often just before landfall. The hurricane strength decreases rapidly once it hits land.||Air pressure and wind speed are inversely proportional. As the air pressure decreases, offering less resistance, the wind speed increases.|
|1/23/2014 20:40:08||There is an inverse relationship between wind speed and air pressure -- as wind speed increases, air pressure decreases. Faster wind speeds my cause an overall increased 'turnover' of air in the region. This rapid turnover would impede any excess air pressure that might build up with slower wind speeds. Without this constant 'recycling' of air in a region, pressure would then have more time to climb.|
|1/23/2014 22:56:49||Jarrod Parra||I couldn't find data showing the chronological order of the hurricanes listed. I know they are named in alphabetical order, and I believe they are given either male or female names based on what type of 'storm' they are defined as: hurricanes, typhoons, or cyclones.||Hurricanes follow a clockwise pattern of movement. Based on our data pool the origin of the majority of hurricanes come from either the Caribbean, near Mexico, and the NE Atlantic, near Cape Verde Islands and West Africa. Based on our data pool, the majority of hurricanes hit land in the south/eastern region of the US.||Hurricanes form in the summer and fall. These are the hottest months in the Northern Hemisphere, which leads to the 'tropical oceans' reaching over 80 degrees Fahrenheit. These warm temperatures then force moist air to rise and cause thunder storms. Surface winds, and upper levels winds, combine to cause a 'tropical depression.' High enough winds (over 74 mph) in this depression may then lead to the development of a hurricane or other storm.||Hurricanes spin in a counter-clockwise direction. This is possibly due to 'Hadley Cells.' These cells cause warmer surface winds to rotate towards the equator, while cooler surface winds rotate towards the poles.||The region for the greatest risk of hurricanes is along the tropics. Temperatures at the equator are hotter than at the poles, leading to the rising of this hot air due to 'convection.' Thus, Hadley Cells form (cells of convection).||The pattern of hurricane strength is numbered from 1 to 5 based on wind speeds. Following is a list of hurricane categories with corresponding wind speeds (in mph).|
Hurricane strength dissipates at landfall.
|There is an inverse relationship between wind speed and air pressure -- as wind speed increases, air pressure decreases. Faster wind speeds my cause an overall increased 'turnover' of air in the region. This rapid turnover would impede any excess air pressure that might build up with slower wind speeds. Without this constant 'recycling' of air in a region, pressure would then have more time to climb.|
|1/26/2014 22:57:10||Mario Martinez||The data shows that men's and women's names are used fairly evenly...although I could have sworn hurricanes used to be named mainly after females a few decades back, so I wonder if maybe the data doesn't go back far enough?||Just under half the given hurricanes seem to originate in the Caribbean, while the remaining hurricanes originated somewhere in the Atlantic (northeast Atlantic being most common of these). The hurricanes mainly seem to make landfall somewhere in the eastern United States, with the south eastern states being most common. Most hurricanes seem to travel in a clockwise direction. I am unsure why the hurricane spins counter-clockwise and yet travels clockwise (although I want to test it by spinning coins or tops now). I wonder if it isn't because of some sort of need for stabilization or due to some effect of gravitational force?||Most hurricanes seem to occur around August or September. This is probably due to the weather patterns that typically occur during these months in the affected areas.||Hurricanes appear to spin mostly counter-clockwise. This is due to the Coriolis Effect and the fact that a majority of hurricanes originate in the northern hemisphere.||According to the data, hurricanes seem to have the most force (in terms of wind speed) over the ocean and gradually lose that force as they continue inland. While the risk of hurricanes would undoubtedly be greatest on the ocean itself if people were caught in one, as far as total damage goes, coastal towns (or worse, islands) seem to be at greatest risk.||Hurricane strength seems to steadily build as long as the hurricane remains over open ocean and typically diminishes over time after hitting a high point (diminishing especially quickly once it hits land).||Air pressure and wind speed seem to be inversely proportional in most hurricanes. Because wind is created by air traveling from higher to lower pressure, it is possible that it displays a faster speed in lower pressure since it picks up speed as it travels from higher to lower.|
|2/10/2014 5:11:50||J. Harrison||From 1957 to 1969 female names. Then from 1979-94 all male names. The years in between a mix, but 2007-2008 all male.||The seem to form near the landmasses on either side of the ocean (Mexico, Africa) and are then redirected due to the land decreasing speed and increasing air pressure.||They hit in the hottest months, mainly August and September. I am not sure why, and from the data I can't explain it. But in the reading it said "The sun heats the air over the equator more than at the poles. This differential heating causes warmer, less dense air near the equator to rise, and cells of convection develop. These are called Hadley cells."||Counterclockwise. If I understand the figure, the wind directions in the Hadley Cell to the north of the equator flow this way.||Florida and Texas are the two states with the greatest risk. This is due to their proximity to both the equator and the ocean. Once the hurricane makes landfall its windspeed decreases, so these coastal barrier states take the brunt of the storms.||The highest speeds are over sea, but I didn't see a pattern regarding most likely to be catagory x. However, my guess is higher category storms start further from land. Then as they move closer to land the speed decreases as they turn back toward the ocean.||The air pressure and windspeed have an inverse relationship.|
|6/16/2014 23:03:28||Jason Aiken||It appears to me that the names of Tropical Cyclones repeat. From our class data it appears that about half of the names are female and half are male. Names can be retired. I think this is usually a sign that it caused a lot of damage.||Hurricanes generally start over the Atlantic. They move West by North-West. They pick up speed over the ocean, then fizzle out over land. My hypothesis is that they move West because the earth turns beneath them, and North because of the wind direction of the Hadley coil.||I would guess that hurricanes occur at the end of summer because there is more energy in the water at the surface of the ocean after it has been warmed all summer.||Counter-clockwise. I guess this is because as the earth spins, the speed of the ground is greater under the southern edge of the hurricane compared to the northern edge.||Storm surge causes much of the hurricanes damage.|
Hurricanes cause the most damage if you are in a low lying area close to the coastline. I would also guess that you are in the biggest trouble if you are in a structure that is not strong.
Low islands off the Florida coast are at high risk.
|Category 5 hurricanes have the highest wind speed. Because they can no longer feed off the warm water, they fizzle out over land.||Lower air pressure in the eye of a hurricane goes along with higher wind speed.|
Air moves from high pressure to lower pressure. If the pressure of the eye of the hurricane is very low, then the wind speed will be very high.
|6/17/2014 10:47:13||Yuki Kata||Male names, such as Andrew, and female names, such as Katrina, appear to be evenly distributed as shown in the graph: male 52% and female 48%.||Hurricanes are originated in the central Atlantic ocean because the sun heats up the tropical ocean to over 84 degrees during the summer season. It first moves westward, then changes direction toward north. It is hypothesized that the hurricane moves westward due to the trade wind that blows from east to west.||Hurricanes most often occur in September. This is because, during the summer season, the sun heats up the tropical ocean, and its effects are felt in September.||Counterclockwise. It is called tropical depression, which is created when upper-level winds and surface winds come together to form a circular pattern. My understanding of the reason for this has something to do with the spinning of the earth and the Coriolis Effect. The air flows into a low pressure center like water going down a drain.||The risk of hurricanes is greatest when they land. The Caribbean islands are the most vulnerable. The next is probably Florida because it is vertically long, which means that there is greater probability of hurricanes' landing.||If you look at the path of Andrew (1992), the hurricane starts out being rather weak, and then it gradually gains strength as it moves westward. It is the strongest in the Caribbean, and starts losing its strength, usually turning into a tropical storm after landing.||In TV weather reports, low air pressure brings bad weather, so the lower the air pressure, the faster the wind speed.|
|6/19/2014 14:20:38||Rita M. Romo||It appears that there are more hurricanes that are named using male names but it is only a slight difference based on the date that I am seeing now. Male 52% and Female 48%.||Most hurricanes seem to originate in the Atlantic and move west towards land where they loose some of their strength.||I would guess that hurricanes happen in the summer since they are due to the heating of the water and the summer would be when it will most likely be heated.||It appears that the direction the hurricanes appear to spin is counterclockwise based on the data 86% clockwise vs. 14% clockwise. I have no clue as to why that is, perhaps it has to do with earths rotation.||It seems that the risk of hurricanes are the greatest if you are living at the coast or on an island. They are at the greatest risk because it looks like the hurricane losses its strength as it hits land but its a gradual loss of strength so if your at the coast or on an island you are still getting a hit by the hurricane at its strongest point or at least the strongest it will be on land.||The hurricane will have its greatest strength over water and will lose strength as it hits land. It is most likely to be a category 4 or 5 over water.||It seems that air pressure and wind speed are inversely proportional as one goes up the other goes down.|
|6/19/2014 19:37:06||Wesley Manson||There is a switch between male and female names and it seems that it may be going in an alphabetical order.||Hurricanes seem to start near Northern Africa and end up coming down to Eastern US. As they move to land, they lose speed and pressure increases. The warm ocean water heats them up, while pressure falls and wind speed picks up. Their movement could be explained by the warm waters along the coast line.||It seems there is more hurricanes in the summer, perhaps due tot he warmer waters.||They spin counterclockwise. This might be due to the wind pattern above the oceans.||It seems that the most dangerous place to live when thinking about hurricanes is by a coast or on an island. Hurricanes lose strength as they go inland, so this means that if you are by the coast, you will get the worst of the hurricane.||Hurricanes gain strength over water and lose strength over land. The higher the category, the more time they most likely spent over water, since this is where they tend to pick up speed,||As one goes up, the other goes down. Less air pressure could mean there is more room for the wind to pick up speed.|
|6/20/2014 11:10:23||Anna Tahmasian||According to National Hurricane Center, since 1953 the hurricanes has been named from a list that each year alternatively changes from a female name to male name. There are 4 groups of regional names: |
1. Atlantic Names
2. Eastern North Pacific Names
3. Central North Pacific Names
4. Other Basin Names (Worldwide)
There are 6 lists, so every 6 years the names are repeating again.
|There is a phenomenon called global wind pattern which is divided to 3 wind belt: |
1. Polar Easterlies: From 60-90 degrees latitude.
2. Prevailing Westerlies: From 30-60 degrees latitude (aka Westerlies).
3. Tropical Easterlies: From 0-30 degrees latitude (aka Trade Winds).
the movement of the hurricane depends on the wind belt, for example if the wind belt locates at the Atlantic it is driven by easterly winds toward west and eventually goes north and lands on East Coast of the United States.
|The hurricane usually happens at the end of summer after the waters heat up, therefore the possibility of having hurricane starts at June and reaches the high level between August and September||The Coriolis force is the reason that wind starts to move to the right in the northern hemisphere and therefore gradually spins counterclockwise, and it moves clockwise on the southern hemisphere for the same reason. Another example of this can be seen on the toilets and sinks swirling counterclockwise on the northern and clockwise swirling on the southern hemisphere.||Landfall is the location where the hurricane hits and again it depends on the wind belt where the winds start, the landfall in northern hemisphere could be East Coast of the United States as well as Gulf of Mexico.|| Wherever the eye of hurricane moves is the most strength and has the most damage.|
There are 5 categories as follows:
1. wind has 74-95 mph speed and has no real damage, some coastal flood and pier damage.
2. wind has 96-110 mph speed and damages some roof, door, and window damage also more damage on the coasts.
3. wind has 111-130 mph speed and destroys residential and some utility building, also mobile homes and floods on the coast.
4. wind reaches 131-155 mph speed and destroys most of residential areas and heavy damages on the coasts and piers.
5. winds reaches its maximum speed 155+ and complete damage on residential areas and flood on shoreline; may ask for evacuation.
|While the temperature goes up, the air pressure goes down. The changing on temperature and pressure speed up the winds and form hurricane.|

|6/22/2014 21:27:11||Arda Jesralyan||The wind increases while the pressure drops.||The origin of Irene comes from West Africa and since there is low pressure winds near the continent, that is why it drifts towards the ocean until it hits the wind global wind pattern located within the Atlantic Ocean.||It happened during the late summer when the region near the African continent has a warmer climate.||The hurricane winds spin in a counter-clockwise motion due to the global pattern of the winds found near the equator of the Atlantic Ocean.||The greatest risks of hurricanes tends to appear near the shores of the East Coast due to the close proximity between land and water.||Hurricane Irene is labeled as cateogy 1; when it hit land, wind speed picks up due to the amount of objects found within its proximity.||Air pressure tends to remain constant and decrease as wind speed picks up. It greatly increases once it hits the land because there are more objections on land such as trees and houses.|
|6/23/2014 18:35:05||Martha Rios||From the collaborative research completed, I have noticed that most of the hurricanes are named after males. I also have noticed that they are named alphabetically over a period of time.||The origins of hurricane storms appear to be located near the equator. They tend to travel in a clockwise motion and reach high speeds over the sea. However, hurricanes appear to have a slower pattern once they hid landfall. Storms may form over warm water because the warm air rises which causes the formation of clouds, mixed with winds which create a continuous flow of heat and water, developing a storm.||Hurricanes appear to mostly form during the late summer months and early fall. This may be due to the rise in temperature of water over the summer months.||Hurricanes appear to spin in a counter-clockwise movement. This could be due to the fact that wind patterns in the Hadley cell, where most storms seem to originate, move in a counter-clockwise movement. It also depends on whether it originates above or below the equator. In the northern hemisphere, the storm travels in a counter-clockwise directions, whereas it moves in a clockwise direction in the southern hemisphere. This is due to the Coriolis effect.||The risk of hurricanes is greatest over land areas that are closer to the equator near the ocean. Because hurricanes travel in a clockwise movement, it is also the eastern borders that appear to have the most danger of being in hurricane weather.||Hurricanes begin with a small storm that tends to gather speed. As long as it is over water, the storm continuous to be fueled by the continuous change in air pressure. If a storm's path hits landfall, it loses some of its momentum because it no longer has warm air rising from water, which causes it to lose its speed.||As the air pressure declines, the wind speeds of a storm begin to accelerate. When the warm air rises, it causes low air pressure. The surrounding air with higher air pressure pushes into the area with low air pressure. The new air rises again and the process begins to be fueled by clouds and winds. The continuous repetition of this process with the low pressure allows for the new air to flow more quickly keeping the wind speeds higher.|

Based on the outside class research, the current name system started in 1979 and there are six lists of names that are used and rotate. The same set of names will be used every six year. The names can be retired if it caused many deaths or damage.||Hurricanes develop in different areas of the tropical North Atlantic. In general, hurricanes are steered by global/environmental wind. In addition, hurricane tends to drift northwestward in the northern hemisphere due to a process called beta drift.||Hurricane season reaches its peak between mid-August and October in the northern hemisphere because the oceans reach their warmest temperatures which is favorable for tropical cyclones.||Hurricanes in the northern hemisphere spin counterclockwise due to the Coriolis force that pulls the winds to the right in the northern hemisphere.||Landfall happens when a center of hurricane intersects with a coastline and the eye moves over land. When a hurricane makes landfall, the results are devastating. Damages can be caused by storm surge, strong winds, heavy rain, and tornadoes.||The Saffir-Simpson Hurricane Wind Scale is categorized into 1 to 5 based on the intensity of hurricane. Category 1 is when wind speed is between 74 -95 mph and category is 5 is when wind speed is more than 156 mph. When a hurricane travels over land or over cold water, the storm tends to weaken.||As air pressure drops, wind speed increases because the wind moves out of areas of high air pressure and sweeps into areas of low air pressure.|
|6/24/2014 15:14:42||Ella Mkrtchyan||Over the years, the plan for naming hurricanes has changed. The names are given in alphabetical order. Before, all the names were female, but now the names are alternated between a male name and a female name.||The movement of wind throughout the globe is called the global wind pattern. The surface winds of each hemisphere are split into wind belts. The path of the hurricane is dependent upon the wind belt in which it is located. Because of this, the Gulf of Mexico and East Coast of the United States are at risk to experience one or more hurricanes each year.||According to class data, most of the hurricanes occurred during August and September. This can be because it is the hottest time of the year, and more water evaporates.||In the northern hemisphere, hurricanes are low pressure systems and they rotate counter clockwise. High pressure systems rotate clockwise. In the Southern Hemisphere, a low goes clockwise and the high pressure goes counter clockwise. The reason for this is the Coriolis effect; In the northern hemisphere, any slow displacement of any fluid: air mass or sea water, is deviated to the right hand.||The greatest risk of damage from hurricanes is in cities that are close to the ocean because according to class data, hurricanes move the fastest over water. Hurricanes also decrease in speed when they continue inland.||Hurricane strength depends on the maximum sustained wind, or the knots. It is much more likely to have a higher level hurricane if it is over water because hurricanes slow down when moving over land.||Pressure and Wind speed appear to be inversely correlated. Air moves in a horizontally and rotates due to pressure. In low pressure air rises and rotates fast in the atmosphere and forms faster winds.|
|6/24/2014 15:26:05||Henry Sanchez||Hurricanes are named after a female or male name. The hurricanes that occur early begin with letters in the beginning of the alphabet: a, b or c. Hurricanes that occur towards the end of the hurricane season have names that begin with a letter that comes later in the alphabet.||Hurricanes originate around the gulf of Mexico. Hurricanes then travel northward and build up energy. As hurricanes travel north, they at around 60 degrees latitude. The wind at 60 degrees latitude is pushed downward toward earth.||Hurricanes occur during the Summer and early Autumn. During the summer, the water is warm and adds to the energy needed to create a hurricane as the movement of water travels north.||Hurricanes spin counter-clock wise. The Coriolis effect, which is caused by the spin of the Earth, causes the water and air to move in a counter-clock wise manner.||The risk of hurricanes is greatest along the gulf coast of the Unites States. As a hurricane travels northward, it reaches its highest speed on the coast. As a hurricane hits land, the speed of the hurricane decreases.||Hurricanes are most likely to be a category 1 or 2 when they are beginning to form. Warm waters have not fueled the hurricane enough to reach a high category. As a hurricane travels northward, the warm waters of the gulf coast fuel the hurricane and may cause the hurricane to reach a category 4 or 5. As the hurricane hits land, the hurricane will slow down and eventually disappear.||There is an inverse relationship between air pressure and wind-speed. As air pressure increases, the wind-speed decreases, and as air pressure decreases, the wind-speed increases. Wind travels from areas of high pressure to areas of low pressure.|
|6/28/2014 16:01:59||Rachel Gardner||I did not notice any distinct patterns when naming hurricanes. They seem to be in rotation.||Hurricanes seem to originate in the middle of oceans near humid climates. Many hurricanes appear to move clockwise. I think they start in humid climates because they need a lot of moisture.||They tend to start in the summer and fall. This is probably because there is a lot of hot moisture during those seasons.||They appear to spin counterclockwise. I think that this has to do with what side of the equator the hurricane is on.||Florida has the most hurricanes with Texas as second.||Most hurricanes are between 3 and 5. The hurricane strength decreases when it hits land.||They are inversely related. More wind alleviates the pressure.|
|7/4/2014 16:00:30||Robert Stevens||They are ordered alphabetically.||Hurricanes originate over the Atlantic ocean and head in a clockwise trajectory beginning at their point of origin. Their spin may drive them a westward, but maybe as they lose energy jetstreams drive them east again.||They seem to be in Sept / Oct / November. It probably has to do with the combination of when Atlantic waters have been heated following an entire season of summer sun.||Counter-clockwise. Perhaps it has something to do with the rotation of the earth?||The shoreline. According to video one truly dangerous aspect of a hurricane is the storm surge. Thus, anything closest to the shoreline is especially susceptible to damages.||Windspeed decreased when hurricanes hit land, thus hurricane strength perhaps increases most when it spends the most time above water, making it more likely to be a higher category hurricane.||As air pressure decreases windspeed increases (inverse relationship). Maybe the decrease in air pressure frees the hurricane up to move faster.|
|7/11/2014 18:15:54||Oscar Tapia||50% are male, 50% are female. The trend used to be majority female, but that has changed in recent years.||The origin of Hurricane Sandy was in the Carribean and it moved northwards through Cuba, along the eastern coast of the United States before finishing off as an extratropical storm over New Jersey and Pennsylvania. Winds along the east coast tend to blow northeasterly, which may explain the movement of the Hurricane.||The timing of hurricanes occur mostly in the later months of the year, in August and September. Since hurricanes require heated water moisture, and there are higher temperatures as you approach the Equator, this might explain the timing.||Hurricanes appear to spin in a counter clockwise fashion. This is due to the Coriolis force, which involves a counteraction of momentum due to the spinning of the Earth.||The risk of hurricanes is greatest to countries that are in the Caribbean and toward the Equator.||Hurricane strength is lower as it is over the water, but higher as it hits land. According to the data on Hurricane Sandy, it pretty much maintained a Category 1-2 through most of it's travel, but hit Category 3 once it went overland into Cuba.||The relationship between air pressure and wind speed is an inverse one. When air pressure drops, wind speed increases, and when wind speed decreases, air pressure increases.|
|10/9/2014 21:40:34||Darshana Vakharia||The names seem to be equally divided between male and female.||Hurricanes originate on sea as the temperature of the water rises to above 82 degrees. Warm air rises and comes in contact with surface and upper layer winds creating thunderstorms.|
Hurricanes form on account of the Coriolis effect, where the Coriolis force acts perpendicular to the rotation axis of the earth.
|Hurricanes tend to peak from August to October because ocean temperatures are warmest during these months in the Northern Hemisphere.||Hurricanes appear to spin in a counter clockwise direction. This is because the earth is spinning around its axis and pulls the wind to the right in the Northern hemisphere and to the left in the Southern hemisphere.||The risk of hurricanes is greatest along the coast. This is because hurricanes can cause storm surge where the rise in water level can cause extreme flooding in coastal areas. In addition, consistent pounding of violent waves can destroy structures which are not typically designed to withstand such powerful waves. Erosion from waves and tides created by hurricanes can damage coastal highways and foundation of buildings causing massive destruction. The strength and height of the incoming tides takes a toll on life as well.||Category 1: winds 74-95mph. No real damage to building structures. Some coastal road flooding and pier damage.|
Category 2: winds 96-110mph. Structural damage to small building. Floods cause damage to larger building. Considerable damage to mobile homes, piers, and vegetation.
Category 3: winds 111-130mph. In addition to damage caused by category 2 hurricane areas lower than 5 ft above sea level may be flooded inland.
Category 4: winds 131-155mph. More extensive structural damage, major erosion of beach areas, and areas lower than 10 ft above sea level likely to be flooded.Evacuation of residents within 6 miles of shoreline may be required.
Category 5: winds greater than 155mph. Complete roof and building structures likely to be damaged. Areas lower than 15 ft above sea level will flood and evacuation of residents within 10 miles of shoreline required. Extensive and severe damage to life and property predicted.
|Pressure and Windspeed are inversely proportional in a hurricane until reaching the eye of the hurricane. Inside the eye the windspeed and pressure are directly proportional.|

|10/22/2014 21:26:18||Tove Aitchison & Bertha Fernandez||Common names||Highest speed over sea, Originates over sea, traveled clockwise. Because the hurricane picks up energy from the ocean.||Most hurricanes are during August and September, due to warmer ocean currents and SST.||Counter-clockwise||South East Coast of the United States has the greatest risk. Florida and Louisiana are coastal, low-lying areas close to the equator where SST's are higher.||It decreases when it hits land.||As air pressure increased wind speed fell, and vice-versa.

|10/22/2014 21:26:24||Akiko and Martha||Equally named both male and female.||The origin of most hurricanes appear between the Caribbean and NE Atlantic near west Africa. The destination always appears to end over land. The pattern of movement also appears to spiral upward in a clockwise motion. Hurricanes may be affected by ocean currents.||Hurricanes usually appear towards the end of summer and beginning of fall, between the montsh Aug.-Oct.||Majority of the hurricanes appear to spin counter-clockwise.||The risk of hurricanes is greatest over Florida. Most hurricanes seem to travel along a path in which Florida lies.||The pattern of hurricane strength appears to be strongest over the sea and decreases over land. When it hits land, then the strength of wind speeds dramatically decreases.||The pressure and windspeed of hurricanes appear to be inversely proportional.|
|10/22/2014 21:26:29||Theresa, Jess and Stephen||The evenly named by male and female names. The hurricane names might be used multiple times.||Most originate over the Atlantic Ocean near the equator and move to the east.||Most occur in August - October(90%). There are a few as early as June and as late as November.||Most spin counter clockwise. Could be influenced by earth's rotation and weather patterns. Clockwise patterns occur earlier in the year.||The relationship is inversely proportional.|
|10/22/2014 21:26:40||Gloria Hernandez and Juliana Capra||Overall there are more male names, but it's insignificant.||Most originate in the Caribbean and travel away from the Equator; moving northbound. The heat from the equatorial region and the differing pressures from land versus water in relation to the geographical shape.||Most hurricanes happen in the late summer and early fall months. This might have to deal with the change in air pressure and ocean temperature.||The majority are counter clockwise spinners. This has to deal with the Coriolis effect.|
|10/22/2014 21:26:36||Debbie and Yina||equal in gender||Most start in the Caribbean. Most do not cross the equator.||Most occur in the late summer and early autumn (Aug-October). Most are in September.||counterclockwise||Florida and throughout the Gulf of Mexico.

|10/22/2014 21:26:43||Mara and Lilach||Names are 50/50 gender split.||Most start in the Caribbean and make landfall over Florida and Texas. They are starting just above the equator so it may have to do with centrality and then as the Earth spins it moves up in a pattern that corresponds to the speed of the Earth's spin.||Most occur during August and September.||They mainly spin counter-clockwise. It may have to do with the Earth's rotation.||North America. (Texas/Florida/South)||Goes down.||Air pressure and wind speed are inversely proportional. Bernoulli's principle explains this.|
|10/22/2014 21:26:59||Allison Shiff and Andrew Salg||Most of the hurricanes happened to be named after men and women, but is split very evenly.||39% of the hurricanes originate in the Caribbean near Mexico. A possible reason is because of the warm water temperature and the cold air meeting.||The timing of the hurricanes mainly happen around parts of the summer, or towards the end of summer. A possible reason why this happens is because the warmth begins to leave the ocean water at this time.||Most of the hurricanes happen to spin counter-clockwise because of equatorial winds.||The risk of hurricane is greatest is in Florida because they are a peninsula. They are surrounded by warm waters where these hurricanes can build speed.||It is most likely to be a category 5 over a open ocean.The hurricane speed slowed down when it hit land.||The relationship between air pressure and windspeed is inverted. A potential explanation for this is because as the hurricane spins it loses pressure, and as it slows the pressure is allowed to build up.|
|10/22/2014 21:27:31||Chris + Dennis||Names are short.||Spinning counter clockwise would cause an repulsive force that makes you hook clockwise. They move from warm to cold.||They occur during the hottest months of the year. The molecules in the air have the most energy.||Most spin counter clockwise. Corriolis forces.||Near the carribean.||5 is most likely, but slows on land.||Inverse. Moving fluids have lower pressure.|
