Weather & Atmospheric Dynamics

Improve our understanding of atmospheric circulations ranging in scale from hurricanes to extratropical storms and the general circulation, with an emphasis on extreme weather events and the interplay between weather phenomena and climate variability and change, using comprehensive high resolution atmospheric modeling and idealized dynamical studies.

Research Projects

Hurricane Modeling

Investigate hurricane sensitivity to climate change using a variety of tools, including global models, regional models, and the GFDL hurricane forecast system. Continue to improve the GFDL hurricane forecast system and its operational implementations.

High Resolution Global Atmospheric Modeling

Develop high resolution atmospheric models for improved simulations of the atmospheric climate, and for studies of regional climate change and of extreme weather.

General Circulation Dynamics

Study a variety of idealized general circulation models to develop our understanding of the atmospheric climate and help optimize GFDL's atmospheric model development efforts, with an emphasis on the interplay between the atmospheric hydrological cycle and the general circulation.

Global Modeling of Tropical Cyclone Activity

As part of the development of a new generation of atmospheric models with finer spatial resolution, we have been examining a variety of issues related to tropical cyclone statistics, including inter-annual variability, seasonal predictability, and the effects of global warming. The cornerstone of this research is an atmospheric model with approximately 50km horizontal resolution that provides an impressive simulation of the climatology of tropical cyclones, including their geographical distribution and seasonal cycle in different ocean basins. It is intriguing that a model of this resolution can do so well in this regard, and it is this success that has allowed us to address a number of important issues related to tropical cyclones.
