Research Interests

My main research focus is on investigating the large scale dynamics of the mid-latitude troposphere. The phenomena that I have investigated range from baroclinic waves/cyclones up to storm tracks and the large scale mean circulation. 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 GCM 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

  • Variability and trends of storm tracks
  • Storm track dynamics
  • Dynamics and life cycle of baroclinic waves and cyclones
  • Wave/mean flow interactions
  • Tropical/extratropical interactions, tropical meteorology
