LONG-TERM GOALS The long-term goal of this project is to improve the treatment of convection and the prediction of convective precipitation in the Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS® 1 ), by including selected land-surface and urban canopy schemes in COAMPS, along with tools that will allow the user to choose the optimum ones for selected nested-grid configurations. OBJECTIVES The objectives of this project are to: (a) integrate land-surface models and urban canopy

APPROACH Our approach is to use COAMPS to study the impact of land-vegetation processes on the prediction of mesoscale convection over central Europe during summer months. This will be accomplished by implementing new and more detailed surface databases into COAMPS, developing a new data assimilation system for surface parameters, and performing numerical tests with COAMPS to determine the importance of selected parameters within the land-surface model (LSM). The results of this study will be applicable to similar continental areas. 1 COAMPS® is a registered trademark of the Naval Research Laboratory.
