Research on the Factors of Wind Direction and Distance in the Impact of Sand Source on its Neighborhood: An Example from Three Regions of Southern Xinjiang, China

Abstract:

Wind-blown sand is now one of the most serious environmental issues around the world. The properties of wind and the distance from sand source to the affected locations are two most important factors for assessing the effect of the sand source on its neighborhood. To acquire better assessment result, the methods of wind vector interpolation and the measurement of the distance from sand source to the affected location have been researched. The adopted interpolation procedure for wind vector includes three steps: 1) resolve the existing wind vectors, 2) interpolate based on the resolved wind vectors using inverse distance weighted interpolation, and 3) compose the interpolated wind vectors. This paper also presents a new measuring method and its theoretical basis to acquire the distance from sand source to the affected location. This paper claims that the distance along the wind direction, based on which the range of the damage can be acquired, is more valuable for the damage evaluation. The presented method has been applied to three regions of Southern Xinjiang, China.
