Research methods

Combine observations, theories and modeling to understand climate and its impacts.

In particular, we use high-resolution (50 km and higher) global climate models (GCMs) to explore extreme climate and weather events, e.g. tropical cyclones, extreme precipitations and heat waves.

Example experiments from GFDL-AM2.5C360

GFDL-AM2.5C360: ~25 km resolution GCM (directly simulate intense hurricanes).

Historical experiment: 10 ensemble members over 1871-2020.

RCP4.5 experiment (future projections): 3 ensemble members over 2021-2100.

TXx: annual maximum of daily maximum surface air temperature.
