Abstract : ANALYSIS OF SPRING DUST STORMS OVER SAUDI ARABIA FOR THE PERIOD FROM 1978 TO 2008 Khaled Ali Abdullah Alabbasi ABSTRACT The statistical and synoptic study of dust storms over the Arabian Peninsula (AP) were studied using surface observations from 27 surface stations and meteorological data from the NCEP/NCAR reanalysis data set for the period from 1978 to 2008. The study shows that spatially, the northeastern stations and the Dawasir station are the most affected by dust storms and that temporally, the study period can be divided into two subperiods before and after 1995, with a pronounced increase before 1995 and a smooth increase after 1995. The synoptic study of the spatial distribution of dust storms over Saudi Arabia reveals three main atmospheric systems: frontal systems over the northern region, Red Sea Trough (RST)-related systems over the western region and thermal low systems over the eastern region. Additionally, the synoptic study shows that all the atmospheric systems are associated with a favorable pressure (geopotential) gradient area and that the shape and strength of the maximum wind and upper layer atmospheric regimes are suitable for integration of the whole atmosphere. Moreover, these dust-related atmospheric systems are associated with different degrees of strength of the thermal low in the southern area, and the strength of the thermal low system is highest in association with the eastern region.
