Study on the Spatial Distribution of Precipitation in Shandong During the Passing of Typhoon Dusuri
It is one of the important means to reduce flood and waterlogging disasters to draw the spatial distribution map of precipitation in the study area during the passing of typhoon by using scientific methods.In the paper,the inverse distance weighting method and Kriging method are used in spatial interpolation analysis of the precipitation data of 123 meteorological stations in Shandong during the passing of typhoon"Dusuri".The study results show that the inverse distance weighting method has the best spatial interpolation accuracy,with R2 0.98 and RMSE of 0.52 respectively.The Kriging method also shows satisfactory results with R2 of 0.89 and RMSE of 1.46 respectively.In general,the inverse distance weighting method is more suitable for the study of the spatial distribution of precipitation in this paper.
