Research Interests My research focuses primarily on two areas: (i) Mesoscale dynamical processes in the middle atmosphere. I am interested in gravity waves, their interaction with shear wind flows in the nonlinear and resonant regime, and their impact on the atmospheric parameters and minor atmospheric constituents, such as stratospheric ozone. In particular, gravity waves can be responsible for strong variations of the stratospheric ozone and for anomalously low temperatures at polar latitudes that trigger the formation of Polar Stratospheric Clouds and give rise to ozone-depleting chemical reactions on aerosol particles. (ii) Modeling of large-scale and mesoscale atmospheric transport and mixing. Current project includes modeling of the transport of passive tracers by global-scale winds. By using the method of Lagrangian trajectories and Green's functions, we compare large-scale transport properties found from model simulations and observations. We are interested especially in the role of deep convection in atmospheric transport. Our research in mesoscale transport modeling aims to improve the understanding of the air pollution problem in the Houston-Galveston area. By using trajectory analysis of meteorological simulations, we analyze the origin of air parcels which form high ozone clusters.
