Parameterization of Cumulus Convective Cloud Systems in Mesoscale Forecast Models

Abstract

The long-term goal is the development and improvement of the microphysics parameterization of cumulus convective clouds in mesoscale numerical weather prediction models. The objectives are to conduct detailed studies of cloud microphysical processes in order to develop a unified parameterization of boundary layer stratocumulus and trade wind cumulus convective clouds. Develop a parameterization of subgrid cloud variability that in combination with the unified parameterization of conversion/sedimentation rates will provide a complete formulation of microphysical processes in convective clouds for use in mesoscale forecast models. Test the parameterization using COAMPS model in simulations of convective cloud systems.
