基于SuperMap的全球沙尘暴空间格局研究

Research on spatial pattern of global sandstorm based on SuperMap

沙尘暴危害性大,造成的损失极高,对沙尘暴这一灾害性天气现象进行空间格局研究具有重要意义.基于沙尘暴灾害特点的特殊性,利用SuperMap软件制作了2005—2014年的全球沙尘暴空间格局变化图,以中亚、北美、北非和澳大利亚四个沙尘暴爆发最为严重的区域为例进行研究,研究全球沙尘暴移动变化情况、空间分布特点以及驱动机制.相关研究为今后深入分析沙尘暴的形成机制提供借鉴.

The sandstorm is very harmful and the loss is very high.It is of great significance to study sandstorm,a disastrous weather phenomenon.Based on the particularity of sandstorm disaster,the spatial pattern change map of global sandstorm in 2005—2014 was made by using super map software.Four regions with the most severe sandstorm outbreaks in Central Asia,North America,North Africa and Australia were taken as examples to study the movement,change,spatial distribution characteristics and driving mechanism of global sandstorm.The relevant research provides a reference for further study on the formation mechanism of Sandstorm in the future.
