Our main objective is to test the hypothesis stated by previous studies, i.e. moisture and vertical velocity played a major role in the generation and maintenance of the convective cycles associated with the pre-tropical cyclone system as it traveled westward across Northern Africa. Originally, mountain effects generate vertical velocity and moisture, and as the system travels westward these parameters are controlled further by environmental factors. With the mountains in central and western North Africa replaced by flat terrains, we found that the mesoscale convective system is weakened and the convective cycles less evident. As the system moves west across Africa, adequate moisture fluxes are guided by the convective development, and the AEW is slightly adjusted by mountainous downstream from the EH region.
