In this study, effective synoptic anomalies in the occurrence of early heat of Andimeshk synoptic station during the statistical period 1390-1360 with an environmental approach to rotation were investigated and from altitude data related to 500 and 700 hPa and ground level pressure in the geographical area 0 to 90 degrees East longitude and 0 to 60 degrees north latitude were used and related maps were drawn in Grads software environment. Data from the National Center for Environmental Prediction Analysis and the National Center for Meteorological Research (NCEP / NCAR) as a 6-hour observation with a spatial resolution of 2.5 2 2.5 degrees showed that the high-altitude subtropical system played a major role. Is in charge. During the warm period of the year, a tongue of high pressure from the subtropical Azores that forms in the Atlantic Ocean settles on Iran. The range of operation of this tab extends from the level of 700 to 100 millibars. In this system, lines of the same height are formed parallel to each other. In contrast, sea level is associated with negative anomalies.
