Abstract:

The aim of this research is to study the effects of the pressure systems at the level of 1000 millibares and effect of the upper air waves at the pressure level of 500 mb on the area affected by the heat waves by determining the heat waves that affected the selected stations which were distributed over the area of Iraq, Which affected the station of an oasis or only two climatic stations, and public heat waves that affected three climatic stations and more, and then analyzed the climatic conditions of the two levels. . 1000 and 500 millibars by analyzing the weather maps of the days of heat waves, and the systems that accompanied the general waves were identified at the pressure level of 1000 millibars, which recorded the Indian seasonal decline where the largest percentage was accompanied by (64.4%). At the pressure level 500 millibars the tropical conditions were accompanied by public heat waves, accompanied by dizziness (44.4%).
