Synoptic climatological analysis of 'wet' and 'dry' Red Sea Troughs over Israel

摘要

The Red Sea Trough is one of the most frequent surface atmospheric circulation patterns over the southeastern Mediterranean. This study presents results of a climatological analysis of the Red Sea Trough (RST) based on a new, objective technique for identifying RST situations. The new algorithm was applied to the GEOS-1 reanalysis gridded data set from NASA for the period 1985-1995 and displayed by the GrADS software. Synoptic differences between 'dry' and 'wet' (rainy) RSTs are displayed and also compared with non-RST rain situations.
