Atmospheric dynamics and diagnoses, climate dynamics, synoptic meteorology.
My main research focus is on investigating mid latitude storms, including how to forecast them better from a few days out to a season, how they may change under global warming, and their immense societal impacts. The distinctive characteristic of my research lies in the fact that I employ a wide range of tools in my research, ranging from analyses of gridded atmospheric analyses and state of the art climate model simulations to learn about the basic characteristics of the phenomena, examination of actual observations to validate what have been learnt from the gridded data, and dynamical studies using a suite of intermediate/mechanistic models to achieve better understanding of these observed phenomena. My major research interests and some selected publications are listed below. For more details and a complete list of publications, see my web page.
Major research topics
- Extratropical cyclones – forecasting and impacts
- Dynamics and life cycle of baroclinic waves and cyclones
- Dynamics, variability, and trends of storm tracks
