A Forest fire is one of the hazardous that associated with atmospheric conditions. By studying atmospheric conditions during the fire event can realized this connection. The aim of this study is to analyze synoptic-dynamic natural hazards West Gilan forest fire on July 21, 2016 with a view to the Environmental circulation. For this purpose, the data of the upper atmosphere, sea level pressure, geopotential, vertical velocity atmosphere, wind zonal and meridional atmospheric levels of 2 meters above the ground, atmospheric levels of temperature and Maximum 2 meters surface of Earth and high radiation flux of Above the atmosphere and land surface with using GRADS software drew maps and analyzed. Atmospheric maps analysis results indicate that the establishment of a secondary low pressure center on the western side of the Persian Gulf and its expansion to the northwest of the country And in the middle of subtropical high altitude to 500 hp power package with the geo potential 5960 m Under his thick hot air subsidence for adiabatic heat combined with low pressure at ground level is of the Persian Gulf. Atmosphere's vertical velocity and vorticity maps based on high-altitude subtropical climate of the western half of the country on negative values indicates that confirmed the stability of Atmosphere and fall to the ground is warm from the upper levels. Advection maps analysis at the level of 1000 to 500 hPa temperature showed that the source of heat entering the western half of the country Advection of warm, dry air from the land of Saudi Arabia, North Africa, Iraq and the northern half of the Persian Gulf's warm waters That makes it the hottest day of the summer event and massive fires in large areas of forests have been Gilan West.
