Research Interests

My research focuses on the changes of planetary-scale modes such as MJO, ENSO and NAO with global warming, dynamics responsible for such changes, and their impacts on regional climate. Recently, my scope extends to real-time forecasts of hurricanes and MJO. Numerical models such as CESM, WRF/HWRF and CFS/GFS are my primary tools. Improving the models to better simulate and predict these modes is of my interest as well.
