The long-term goal of this project is to improve the treatment of convection and the prediction of convective precipitation in the Coupled OceanAtmosphere 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. The objectives of this project are to a integrate land-surface models and urban canopy schemes into COAMPS, b evaluate the limitations of the proposed schemes in describing surface-atmosphere interactions during drought conditions, c investigate the impact of land-atmosphere interactions on Quantitative Precipitation Forecast QPF skill, and d validate the COAMPS model performance when using the land-surface and urban canopy schemes. 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.
