Research focuses on increasing understanding of the atmosphere and its role in the climate system, through modeling and observational studies, and to represent that understanding in improved atmospheric models.

Research focus is to increase understanding of the atmosphere through empirical studies and diagnostic analyses of the atmosphere and its interactions with the earth's surface and oceans on a wide range of time scales.

Uses appropriate climate system models to study the response of the Earth system to a variety of forcings, including changes in carbon dioxide, and other greenhouse gases and aerosols.

Research is understanding the large-scale ocean circulation and the dynamics of climate through studies of the important processes in the ocean, in air-sea interaction, and in coupled systems

Enhance the understanding of the workings of the climate system through investigations of past climates and the role of polar regions in climate variability and change

Studies land-atmosphere interactions, in particular, surface forcing of the atmosphere, through model development, application, and observational analyses
