The Impact Of Pressure System Arab Gulf On Iraq Weather and Climate

Abstract

Iraq weather is affected by pressure systems formed over the Arab Gulf, the holistic approach was used in analyzing the maps to address this effect. The research concluded that the Arab Gulf slip recorded (940) repetition for Iraq most of them were secondary slips formed from the Indian seasonal slip, while Arab Gulf elevation recorded (58) repetition controlling Iraq. Repetition of both systems recorded (998) rate (12.4) % of the total number of observations for the period (1992_2002) which was (8034). Relative humidity rate related to the elevation and slip of Arab Gulf was lower than the general rate of same month repetition. Elevation and slip of Arab Gulf recorded on their repetition a temperature rate and wind speed accompanied higher than the general rate for the same month repetition. Arab Gulf slip recorded on repetition (24.2) ml/year as a rate of total rain on the studied stations while Arab Gulf elevation recorded (18.2) ml/year. .
