the temporal and spatial variations of snow disasters were obtained by using least squares

wavelet analysis and Kriging method. There are 208 recorded snow disasters in Shanxi province

approximately once every 13.125 years on average. The mild

moderate and severe disasters accounted for 16.83%

72.60% and 10.58%
