Wind erosion is one of the natural disasters in the arid regions of central Iran is increasingly faced by mismanagement of natural resources in the rise of this phenomenon has had a large impact. Precipitation, temperature and wind are the most important climatic factors that affect this phenomenon. Lack of rainfall, temperature increased and wind speed increased evapotranspiration in the region is moving so knowing the parameters climate can be useful in the management of natural resources and agriculture. Damghan city is including areas prone to wind erosion phenomena in the North East of the country. The purpose of this study is climatic parameters (precipitation, temperature, evapotranspiration, wind) and the months of the dry zone and its impact on wind erosion. Based on the results of the mean daily temperature in the month of May to mid- October dry station cover dominates return, so once reaches of, July, August and September to its highest. Evapotranspiration rates are amount of rainfall over throughout the year, and the potential evapotranspiration to precipitation in the area is 11. In the months of May, June and July wind storm occurrences of cause and evapotranspiration over other months is also expressed in degrees month is greater than rainfall. In the months of August and September is more heat than any other month in the year of drought peak rainfall in the region is at its lowest. Thus the conditions for the occurrence of the phenomenon of wind erosion climatic factors examined in the region are possible.
