Abstract In this research we investigated synoptic pattern of heavy rain 1 and 2 February 2011 in southern and central regions of Iran specially Kerman province. At the first we calculated heavy rain for all of synoptic stations with use Extreme value type1 then thermodynamic characteristics of heavy rain analyzed with use radio sounding and Skew-t data. For analyzing of this phenomenon we used daily rainfall data 32 synoptic stations of southern and central regions and SLP and 850, 500 and 300 hgt maps. In the 5 day periods, we investigated synoptic pattern formation and its trend in weather maps. The results show that main factor of precipitation in region is formation of cut off low on Mediterranean sea. This system act so blocking and with move onto east, it causes that trough of east Mediterranean reinforcement thus west systems penetrate to lower latitude and they get high level of humidity from south seas and they makes sever precipitations in the study area.
