[0029] The present invention will be further described below with reference to the accompanying drawings.
[0030] like figure 1 As shown in the figure, the meteorological forecast method for areal rainfall of hydropower station basin based on GIS partitioning includes the following steps:
[0031] Step (1), using GIS, according to the distribution of each cascade hydropower station in the basin, the river confluence of hydropower stations and the analysis of rainfall climate background, determine the forecast range and division of areal rainfall;
[0032] Step (2), receive five kinds of forecast sub-products through the local area network, the five kinds of forecast sub-products include the meteorological station rainfall forecast, the basin heavy rainfall forecast, the Guangxi neural network 89 station rainfall forecast, the European ECMWF fine grid numerical rainfall forecast and the Japanese numerical rainfall forecast Forecast: The precipitation forecast of the Meteorolo...
