My research interests are in the areas of cloud microphysics, cloud dynamics and radar meteorology. The central problem of cloud microphysics is understanding the development of precipitation starting from the vapor phase. We are conducting theoretical studies of the formation of cloud drops and raindrops, and their size distributions, by the processes of condensation of water vapor and coalescence and breakup of drops. The results of the theoretical studies are compared with observations from field experiments.
In the area of radar meteorology, I am involved in the analysis and interpretation of radar observations of precipitation and the development and testing of new methods for the remote estimation of raindrop size distribution, rainwater content, rainfall rate and water vapor distribution.
