أثر تغير خصائص التيار النفاث شبه المداري و انعكاسها على أمطار العراق للمدة 1995- 2017

Abstract EN

Previous studies by many researchers and international organizations، including the Intergovernmental Panel on Climate Change (IPCC)، have confirmed climate change in atmospheric systems، leading to a change in total climatic characteristics in the upper and surface atmosphere، This study was carried out to investigate the effect the changing characteristics of the Sub Tropical jet stream over Iraq and its reflection on the surface rain-based meteorological systems The analysis of the daily and monthly ritual maps of the site of the jet stream at a height of 12 km، at a level of 200 hpa and according to the movement of the sun، as well as measuring the temperature of the heart of the jet stream and Geopotential height over Iraq for top Synoptic maps، It was found that the axis of the jet stream had a role in influencing the air masses.

The relation between the atmospheric pressure values was determined at 200 hpa and the amount of rain، where the relationship was inverse at the monthly and annual level over Iraq.
