The values of AOT and the Ångström wavelength exponent (α) show a clear annual cycle. These data are categorized into two catalogues in terms of the values of the AOT of the 870nm channel (τ870). One catalogue (71days) includes days with high values of AOT (τ870≥0.75). The most probable "modal" value of α for these days is 0.52. The other catalogue (1162days) consists of the background days with a modal value ~1.1 for the exponent α. This analysis is extended to include water vapor content (WVC), surface wind speed (V), visibility (Vis) and the diurnal temperature range (DTR). Chree's method of superposed-epoch analysis is applied to these parameters in order to compare the variation in the daily averages during days with high AOT values with respect to background days. The high values of AOT during the 71days are positively correlated with aerosol size, near-surface winds and poor visibility. This concludes that the aerosol particles during these days were mostly dust. The mean daily value of the DTR (ΔT) and visibility reduced significantly during these days. This reduction on DTR is a direct result of increasing the atmospheric opacity due to the presence of dust.  ISSN : 0169-8095  Journal Name : Atmospheric Research  Volume : 97  Issue Number : 3  Publishing Year : 1431 AH 2010 AD  Article Type : Article  Added Date : Sunday, November 13, 2011  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email إسماعيل صبّاح Sabbah, Ismail Researcher Doctorate sabbahsom@yahoo.com Files File Name Type Description  31231.pdf pdf Abstract Back To Researches Page
