Cloud Structure and Entrainment in Marine Atmospheric Boundary Layers

Abstract

Our long term goals are to understand the dynamics of atmospheric motions on scales of order 10 m - 10 km in sufficient detail to be able to provide a consistent subgrid scale model that will represent the influence of turbulent transport across a range of scales. The chief objective of the present grant is to better understand the physical processes that control cloud and circulation structure in the atmospheric boundary layer and rate of entrainment of heat and moisture across the capping inversion. This understanding will be used to formulate a consistent, robust single-column model to represent these processes in Mesoscale models for a broad range of boundary layer conditions and forcings.
