Forest fires have always been financial losses, physical and environmental, and the world has changed a lot in Iran. Identify and predict factors contributing to the occurrence of this event can the incidence of human and environmental catastrophes to prevent it. The research to identify effective synoptic patterns in forest fire took place in the city, Boyer Ahmad. Statistics on forest fires, including the location and time of the fire, The area burned by the Agency of Natural Resources Kohgiluyeh Boyer Ahmad, a 10-year period (2006-2015) As well as data needed to draw weather maps The US Climate Prediction Center of Weather America at 12 Zhu Lu The levels of 1000, 850 and 500 hp Pascal was received. The results showed that the fire on the earth's surface low-pressure prevailing pattern Gulf-Pakistan And the upper dominant pattern of Azores high pressure on Iran Underlying increase the temperature and reduce humidity in the area has been studied. Low levels of heat created by low pressure in the suction atmosphere and the scorching deserts of Saudi Arabia and Iraq warm Gulf The study was drawn to the area and consequently increasing the air temperature and the subsequent increase in soil temperature And the moisture content of the soil to a depth of 10 cm ground Anticyclone of the Azores in the middle levels of the high altitude and the atmosphere in the days studied causes subsidence and rising air temperatures in the region were affected by the cyclone. Factors cited an increase in air temperature, relative humidity decreases and the subsequent increase in soil temperature and soil surface was drying. Despite the conditions of fire in forest areas have been easier. The most important measure to reduce the effects of these fires on forest fires by forecasting and identify early trends affecting climate Meteorological Organization And give timely warnings to organizations forestry, natural resources, is fire.
