LONG-TERM GOAL. The long-term goal is to improve the surface flux and boundary layer parameterizations in the Navy s operational mesoscale model, COAMPS. OBJECTIVES. The objective of this research is to systematically evaluate boundary layer parameterizations currently used in COAMPS with a focus on boundary layer mixing and entrainment process in the stratocumulus- topped boundary layer. In particular, we emphasize intercomparisons between model results and observations in order to understand the model discrepancies. Our work in FY03 has focused on understanding the capability of current COAMPS in simulating boundary layer roll structure and stratocumulus- topped boundary layers and the coding to incorporate entrainment parameterization into COAMPS. Observations from past experiment, The Development and Evolution of Coastal Stratocumulus DECS and Dynamics and Chemistry of the Marine Stratocumulus DYCOMS-II are used for this purpose.
