| Abstract: | Through the precipitation simulation experiments using MM5 V3 with various parameters for the low latitude plateau area, the operational system of the MM5 meso scale numerical prediction model is established based on the SGI O350 minicomputer. Its precipitation prediction has a time resolution of less than 60 minutes and a horizontal resolution of less than 10 km. By integrating the radar, retrieved satellite data, conventional meteorological data, and intensive rainfall observation data with the weighting method, a refined rainfall field was generated. Based on the relation between weather background and Landslide/debris flow disasters, the refined weather based monitoring and warning system of debris flow disasters for Yunnan Province is established with the PP ES model, which has a time resolution of 12 hours and a horizontal resolution of 30 km, and can provide the weather based graded prediction products of Landslide/debris flow disasters |
