Dry climate, poor vegetation and relatively smooth surface and neighborhood with plain Lute are the most important factors that brought about wind erosion processes prevail in the Kerman region. Obviously, wind erosion rate and volume of material transfer depends on characteristics of speed and direction also frequency of wind as well as surface and sediment characteristics. The purpose of this study is to evaluate the morphology of sands, the state of effectiveness of wind dynamics and the causes of sand stabilization in the southern Kerman city. The data of this research are wind statistics of synoptic stations surrounding this area and characteristics of sand and tools of research are maps, aerial photographs, satellite images, laboratory equipment and mathematical models and computer software. To achieve the purpose of this research, statistics of wind stations surrounding Kerman obtained and were analyzed by wind rose. The sand samples have been fitted with wind speed threshold and then combined and compared with indicator obtained in laboratory operations. Results of statistical analysis of seasonal wind directions show that the dominant winds in the Kerman area mainly are blown in two major vectors northern and western. The seasonal wind’s vector has been affected by the dimensions of thermal low pressure cyclone dominated in Lut that controlled winds along the margins of the Lut. Evaluating the general wind blowing vector and wind roses also their adjustment with topography of the region indicate that main direction of wind along the area affected by thermal expansion of seasonal cyclone dominant in the summer of Lut is North direction. Then because of Limitation of the scale of thermal cells during winter, wind in Kerman that located in vicinity of Lut is generally taken Western direction. Wind Channelizes along the mountain valleys and topography is effective in changing the direction of local ground- level winds.
