Numerical and analytical studies of geophysical flows and nonlinear waves

My research spans a wide range of subjects, from theoretical fluid dynamics to numerical analysis. My primary research focus is on nonlinear interactions of waves in geophysical fluid flows, i.e., in the atmosphere and oceans. Wave interactions give rise to large-scale phenomena, such as the quasi-biennial oscillation between easterly and westerly winds that is observed in the tropical stratosphere, and smaller-scale phenomena, such as downslope windstorms and turbulence over mountains. It is important that wave effects are represented accurately weather and climate models. My investigations aim to provide us with the needed understanding of the effects of the waves, as well as the mechanisms for their generation and propagation.
