Impacts of Cumulus Convective Parameterization Schemes on Precipitation at Grey-Zone Resolutions: A Case Study over Complex Terrain in upper Northern Thailand

Abstract—Betts-Miller-Janji´c, Kain-Fritsch, and Grell-Devenyi cumulus convective parameterization schemes had been applied in the Weather Research and Forecasting model. This study simulated impacts of various schemes on precipitation over complex terrain in the upper Northern Thailand at grey-zone resolutions during 1-7 August 2008. The results of 3 km resolution show that each cumulus scheme creates different precipitation patterns reflecting the influence of cumulus scheme on the grey-zone resolution. Nevertheless, all the schemes have the capability to reasonably reproduce the main character of spatial distributions of precipitation. Detailed comparison indicates that Grell-Devenyi scheme and the ensemble of three schemes give a better performance of simulating spatial pattern than the other cumulus schemes.

Index Terms—Cumulus parameterization schemes, grey-zone resolutions, precipitation, complex terrain, WRF.
