التحليل الساينوبتيكي للمناخ البارد الرطب لمحطتي الموصل والبصره

Abstract

 The aim of the research is to determine the type of surface and upper pressure system responsible for recording the cool, humid climate in which temperatures range from 17.4°C and below and relative humidity ranges from 61% to 100%. The research found that high frequency of cold, humid weather for the Mosul station was recorded during the observation at 06:00 GMT locally at nine in the morning and the lowest frequency during the observation was 12:00 locally at three in the evening, as for the Basra station, the highest frequency was recorded during the observation at 03:00 locally at six in the morning and the lowest frequency was recorded At 12:00 locally, 3:00 p.m., the highest frequency of the cold, humid climate of the Mosul station was recorded in January, and the lowest frequency was recorded in May. As for the Basra station, the highest frequency was recorded in January as well, and the lowest frequency recorded was in the month of March, as it accompanies the cold climate. Wet climatic phenomena such as rain, fog, mist, suspended and rising dust and thunderstorms. By analyzing the weather maps to determine the pressure system responsible for the cold, humid climate, we find that the sub-polar depression and the European high, and the accompanying grooves and dents at the level of 500 millibars, are responsible for the type of cold, humid climate.
