The Recurrence of the Pressure Systems in The Arab Deserts and Plateaus in Iraq and their Effect on Temperature.

Abstract

Iraq is affected by the recurrence of the pressure systems in the Arab desert and Plateau surrounding Iraq from the East and the south east. To know. The comprehensive text was used Synoptic the maps of the climatic in addition to the temperature by the weather forecast data to conclude the extent of this effect. The Reserch concluded that the pressure system above the Levantine plateau recorded( 12 Anticyclones ,18 cyclones) in a general average of temperature in all the Reserch centers (18.7 in case of antycyclones.19.7 in case of cyclones) between 1996-2000.Furtheermore the pressure system above Nefud desert recorded(20 Anticyclones,198 cyclones) in a general average of temperature in all the study centers(18 in case of anticyclones and 23.8 in case of cyclones). The pressure system above Najd plateau recorded(20 Anticyclones,141 cyclones) in a general average of temperature in all the study centers (21.7 in case of antycyclones.23.3 in case of cyclones) while the pressure system above the desert of the empty quarter recorded(4 Anticyclones, 471 cyclones) in a general average of temperature in all the study centers (21.1 in case of antycyclones.24.6 in case of cyclones).
