The West African Monsoon brings seasonal rains to the Sahel region during the summer months of May to October. During this season, the African Easterly Jet (AEJ) is most strongly developed as a result of temperature and moisture gradients that span the region from the Gulf of Guinea to the Saharan desert. African easterly waves (AEWs) form in association with this jet. It is important to study AEW development and maintenance since AEWs propagate westward over the Atlantic and can foster development of hurricanes. In this study, we use a high resolution regional Weather Research and Forecasting (WRF) Model over West Africa to study the relationship between AEWs and their effect on tropical cyclone formation. We use ERA-Interim data from May 2006 to September 2006 to force the model at the boundary and validate the model runs. ECMWF AMMA reanalysis data were used to help validate the model runs.
