Modeling and Observational Studies of Mesoscale Air-Mass Boundaries and Warm-Season Convective Precipitation

Abstract

Diagnostic and modeling studies have been performed to improve our understanding of, and skill at forecasting, mesoscale weather systems and circulations, In particular, we have investigated: The effects of entrainment and detrainment on convective cloud heating and moistening profiles, The effects of mesoscale water bodies and ocean currents on the large scale environment and transient weather systems, The effect of subcloud-layer evaporative cooling and changes in radiatively produced surface fluxes on low-level circulations, How soil moisture can be modeled, The synoptic climatology of the elevated mixed layer and lid in the southwestern U.S., The life cycle of the lid in the southwestern U.S., and the skill associated with cloud forecasts from the Penn State/NCAR mesoscale model.
