Abstract:

Overall goals of this 3-year study are to 1examine the role of topography in the development of convective systems and 2 assess the orographic influences on cold season severe weather, such as blizzards, lee cyclogenesis, etc. Four approaches were taken to attain these goals 1Implementation of a field measurement program, 2 diagnostic studies of energy fluxes during various seasons, 3 numerical simulation of severe weather development, and 4 evaluation of model sensitivity ot various physical processes. Progress has been made on all four of these fronts in the first year. Keywords Mountains, Atmosphere models Surface energy fluxes, Mesoscale numerical modeling Atmospheric convection, Seasonal variations.
