Rainfall prediction method and device, computer equipment and storage medium

The invention relates to a rainfall prediction method and device, computer equipment, a storage medium and a computer program product. The method comprises the following steps: acquiring rainfall observation data of each rainfall observation station and numerical rainfall prediction data of each rainfall observation station; according to each rainfall observation station, carrying out regional division processing on the numerical rainfall prediction data to obtain numerical rainfall prediction data of each divided region; carrying out matching processing on the rainfall observation data and the numerical rainfall prediction data of each divided region to obtain matching data; iteratively training a to-be-trained rainfall prediction model by adopting the matched data to obtain a trained rainfall prediction model; and inputting the current observation weather information of the target prediction site and the numerical rainfall prediction data of the target prediction site into the trained rainfall prediction mo
