sub tropical jet stream, 300hpa, temperature, iraqAbstract
The jet stream has wide importance in analyzing synoptic maps because it correlates with other meteorological factors, so the study attempted to study the sub-tropical jet stream (SJS) and shows the variation ranges of atmospheric variables on its path depending on highly accurate meteorological maps obtained from (University of Wyoming), and the study tried to show the correlation with surface temperature in Baghdad city depending on data given from automatic weather station that located above Mustansiriyah university building in Baghdad. The study area covers the middle east region focusing on the subtropical jet stream and showing its correlation with the pressure system type over Iraq inside the (300) hPa level. The result showed that the highest surface temperature in Baghdad was recorded after the starting of the subtropical jet stream in its region, and the highest pressure values in (300) hPa were over Iraq while the jet stream is passing its path. The study also showed that the sub-tropical jet stream corresponded with a higher value of temperature inside its path.
