The cyclones originating in the Sahara, represent one of the most important weather phenomena that affect weather and climate of the Kingdom of Saudi Arabia and the surrounding area. The study and classification of these cyclones is an essential step to study and understand the reasons for their formation and change in behavior. In this paper a new method has been used to study the mechanism of Saharan cyclone tracks, using data of the mean sea level pressure available at a four times a day from NCEP/NCAR reanalysis data, for the spring season during the period from 1958 to 2006. The results showed the possibility of using the automated procedure to study the tracks of the cyclones. The results indicated that there are four main cyclogenic areas concentrated around the Atlas Mountains and nearby areas, including (1) the western lee side of the Atlas mountains, (2) south of the Atlas mountain, (3) the area bounded by a 15° east and 22° north, and (4) the region, which lies close to 20° east and 25° north. In addition to the above, the results identified four regions that can be considered as main cyclonic area of Saharan cyclones, (1) central Iraq with south extend at the north of the Arabian Peninsula, (2) west Central Turkey, and (3) the area close to the Black Sea, and (4) the latest one is a small area near the Caspian Sea.
