Abstract

In this study, first pollutants concentration data was obtained. After that for atmospheric right scrolling with using RAOB software and high level atmospheric data of Mehrabad station draw the thermodynamic chart (SKEW-T).In order to analyzing the atmospheric circulations with using European among scale center data base (ECMWF), the related maps draw in GRADS software. In this research, first seasonal trend and number of Pervasive polluted days in a time period of 1390-1396 extracted and analyzed. The founded expresses decreasing trend in pollutants concentration like PM2.5, O3, CO,SO2 and increasing trend in NO2, PM10 concentration in a understudy time period. After that with determining most intensive and inclusive polluted days, paid to analyze the synoptic selected samples. In winter and spring season with penetrating migrant cold high pressure on north half of Iran in sea level and stretching a high pressure on Arabia and Iraq countries in mid troposphere level and confirm to sea level high pressure, was the dominant condition in a time of INCLUSIVE AND SEVERE pollutant occurrence. Also in the summer and fall season similar to them with settling the high pressure on Caspian and north bar of country and spreading the Pakistan low pressure to south Alborz regions and in troposphere mid level with penetrating shallow trough belong to Russia north low pressure on the research area with creating quite wind and decreasing the boundary depth layer provided suitable condition for increasing Tehran’s POLLUTION potential.
