Implementation of Modeling the Land-Surface/Atmosphere Interactions to Mesoscale Model COAMPS
Abstract
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. 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.
