The invention discloses a rainfall forecasting method and system based on multi-mode integration, a terminal and a storage medium. The method comprises the steps of obtaining weather observation dataof a to-be-forecasted region; processing the weather observation data through an ECMWF prediction mode, a JMA prediction mode and a GRAPES prediction mode to predict future rainfall conditions and obtain three groups of prediction data; and processing the three groups of forecast data according to a probability matching set averaging method to obtain rainfall integrated forecast data. According tothe rainfall forecasting method, the forecasting results of a plurality of independent rainfall forecasting modes are integrated according to a probability matching set averaging method, so that theintegrated forecasting result is obtained, the rainfall probability is confirmed according to the historical rainfall situation, the rainfall forecasting result is obtained, the accuracy of rainfall forecasting is higher, and a new rainfall forecasting mode is achieved.
Description
technical field [0001] The invention relates to the technical field of weather forecasting, in particular to a precipitation forecasting method, system, terminal and storage medium based on multi-mode integration. Background technique [0002] With the development of current numerical model forecasting, numerical weather prediction has begun to develop from single numerical model forecasting to multi-model integrated numerical forecasting. In the early 1990s, ensemble forecasting began to appear in the world, and as a new type of numerical weather forecasting, it was highly valued by the meteorological circles of many countries in Europe and the United States. Studies have shown that multi-model integrated forecasting can make full use of the forecast results of each center's models and comprehensively consider the advantages and disadvantages of each model. [0003] At present, the precipitation forecasts in various regions mainly refer to ECMWF (European Medium-Range Weat...
