Climatology of Back Trajectories from Israel Based on Synoptic Analysis

Abstract

The Air Resources Laboratory's trajectory model was used to calculate five-day back trajectories from Israel at the 850 mb pressure surface for five years (January 1978?December 1982). These air flow patterns were evaluated in conjunction with seasonal weather types for which a detailed synoptic analysis and classification of the weather situations prevailing during these air flow patterns has been performed. A significant difference between the typical seasonal trajectories is pointed out. Trajectories reach Israel from five major source regions: 1) northwest Europe; 2) eastern Europe; 3) Saudi Arabia and Jordan; 4a) North African coast; and 4b) inland North Africa.
