Abstract: As a meteor, sand and dust storm results from a special atmospheric movement. But weather was not the only factor, the earth's surface had made a significant effect on its forming and development. It's qualitative to predict sand and dust storm, so Fisher's discriminant was used to analyze historical data of wind and sandstorm in the Hunshandake area. Based on the available high-quality surface and meteorological observation data from 1988 to 2001, the predictors were analyzed by stepwise method to build linear equations of different groups.The testing ratio of the equations were 79.4%.
