Abstract: By using the digital elevation model data derived from 1∶〖KG-*2〗250000 topographic map and the real-time air temperature observation data from meteorological stations, the distribution test of the air temperature data and the spatial interpolation with normal Kriging technique were made, and based on the air temperature lapse rate, solar radiation model of slope, as well as correlation between solar radiation and air temperature, the spatial distribution simulation of mean daily air temperature for the cryogenic freezing rain and snow weather process from January 13 to February 13, 2008 was conducted, with the consideration of the effects of practical altitude, slope, and aspect. The simulation results were tested to be efficient.
