Abstract
Because the current interpolation method cannot meet the accuracy specifications, a new method for spatial interpolation of extreme precipitation is developed. It integrates precipitation, longitude and latitude, elevation, and topography data such as slope and aspect, and it is then simulated by the high accuracy surface modelling method and applied in the Yellow River Basin (YRB). Results show that the integrated method affords a very good simulation precision, with its simulation precision error being far below other interpolation methods. In conclusion, the integrated method for spatial interpolation of extreme precipitation can afford a good solution in topographically complex areas.
