Precipitation, temperature and wind are the most important climatic factors that influence that. Lack of rainfall, rising temperatures and wind velocity increased evapotranspiration in the region. Therefore, identifying the climatic parameters can be useful for natural resources and agriculture management. Khozesstan City is prone to wind erosion in the South West of the country. The aim of this paper is to investigate climatic parameters (precipitation, temperature, evapotranspiration and wind) and to determine dry month of area and the effect of it on In five meteorological stations in Khuzestan province over a 30-year period (Ahwaz, Abadan, Omidiyeh, Aghajari and Dezful) were investigated.. Based on the results of the average temperature in 5 stations the month of April to mid-October, the region was dry, so that, June, July and August seems to be its greatest extent. The evapotranspiration exceeds rainfall all year, and the greatest amount of precipitation and evapotranspiration in Abadan station 18 times 5 times the rainfall was the lowest in Dezful region. Months of June, July and August in each of the five stations and evapotranspiration over other months is causing gusty winds Also the temperatures in these months is more than the amount of rainfall. In the peak months of drought and rainfall in the region is the lowest. Therefore, the climatic factors are caused the occurrence of wind erosion in the region.
