Precipitation forecasting method and device, electronic equipment and storage medium

The embodiment of the invention provides a rainfall forecasting method and device, electronic equipment and a storage medium, and is applied to the field of weather forecasting. The method comprises the following steps: acquiring brightness temperature data of a to-be-detected area; the brightness temperature data is atmospheric window area data acquired through a detection channel of a microwave hygrometer; inputting the brightness temperature data into a pre-trained time sequence rainfall prediction model, and outputting corresponding radar reflectivity data; and determining the precipitation amount of the to-be-measured area based on the radar reflectivity data, and carrying out precipitation weather forecast with corresponding intensity. In this way, the rainfall inversion forecasting algorithm of the microwave hygrometer can be improved in combination with ground radar data, and the method has the advantages of being wide in forecast rainfall coverage, high in forecasting precision and long in forecastin
