Climate Modeling, Climate Change.
My research focuses on climate system modeling and climate change diagnostics, with special interests in understanding of the physics of cloud and convective processes, their relations with atmospheric general circulation and climate variabilities, and parameterizations of these processes in large scale models, through observational data analyses and numerical experiments.
My current works include running NCAR Community Climate Model (CAM2) in weather prediction mode to aid in the development of new physical parameterization schemes and in identifying model errors; seasonal predictions; cloud simulator in CAM2 and comparison of model cloud properties with ISCCP ranging from regional to global scales; model study of cloud feedbacks; observational and numerical studies of the relationship between tropical convection and the clear sky upper troposphere water vapor, and the implications for potential climate changes.
