Title:
MULTI-MODE INTEGRATED PRECIPITATION FORECAST METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/223951
Kind Code:
A1
Abstract:
The present invention relates to the field of precipitation forecast, and specifically relates to a multi-mode integrated precipitation forecast method and apparatus. In the method and the apparatus, the forecast performance of each forecast mode is evaluated, and the forecast effects, at different precipitation intensities, of each mode, and a traditional integrated forecast effect are analyzed; and then, an integration method is improved, namely, a sliding-window method is used to screen out a forecast mode having, within a preset time duration, the best forecast effect at a certain precipitation intensity, the various forecast modes are integrated to generate an integrated forecast mode, and integrated forecast is calculated using probability match set average optimization. In comparison with the differences of forecast effects, at each precipitation intensity, of traditional integrated forecast, a precipitation value, corresponding to an intensity using a mode having the effect which is better than that of the traditional integrated forecast, is converted and provided, intensity by intensity, for the integrated forecast, such that the phenomenon of the forecast effects, at certain intensities, of the traditional integrated forecast being poor can be alleviated, thereby forming optimal integrated forecast that integrates each individual optimal forecast mode.
