In most cases, desert depressions over north Africa form in the lee of the Atlas mountains, Such occurrences are found when a north or northwest air stream from over the Atlantic moves toward the Atlas range, or when a northeasterly wind blows over the western Mediterranean towards these mountains, As shown in Fig. 1, these depressions may follow numerous tracks during their eastward movement. These depressions usually produce severe heat waves and sandstorms (EL Fandi, 1940, Soliman 1958). The phenomenon of Khamsin weather in spring is one of the main problems associated with weather analysis and forecasting in the area of north Africa. In recent years, several formulations of these types of desert depressions have been discussed from the point of view of their sources and supply of heat and energy.
The present paper is an attempt to identify the effect of cyc1ogenetic activity on the trajectory of these depressions.
