| Abstract: | This paper analyzes the formation mechanism and condition of snowdrift, characteristics and orderliness of space distribution, and expounds start-up speed of wind, physics character and aggradation condition of snowdrift. The paper points out the change of wind speed field on the ground from the distributing of different landform and object takes the final effect to the space distribution of snowdrift. |
