[Emmanouil Flaounas] Regional climate model (RCM) is a valuable scientific tool to address the mechanisms of regionalr\n atmospheric systems such as the West African monsoon (WAM). This study aims to improve our\r\n understanding of the impact of some physical schemes of RCM on the WAM representation. The weather\r\n research and forecasting model has been used by performing six simulations of the 2006 summer WAM\r\n season. These simulations use all combinations of three convective parameterization schemes (CPSs)\r\n and two planetary boundary layer schemes (PBLSs)...
