Abstract

The invention relates to the technical field of electric power meteorology, and discloses a heavy rainfall prediction method, system and device and a computer storage medium. Training sets corresponding to different time periods are constructed according to historical weather data, radar echo sequences and heavy rainfall characterization factors, the heavy rainfall weather prediction models are trained by using the training sets to generate a plurality of heavy rainfall weather prediction models, and during actual prediction, according to the time period to which the current rainfall data belongs, a corresponding heavy rainfall weather prediction model is selected for prediction. According to the method, the heavy rainfall weather prediction model is trained through the multi-source training set, and the rainfall condition of the target area is predicted through the same-period heavy rainfall weather prediction model, so that the precision of heavy rainfall prediction can be further improved.

Description

technical field [0001] The invention relates to the technical field of electric meteorology, in particular to a heavy rainfall forecasting method, system, device and computer storage medium. Background technique [0002] Heavy rainfall weather will have a serious impact on the planning, construction, scheduling, operation, and maintenance of the power grid. In order to ensure the stable operation of the power grid, it is necessary to provide a heavy rainfall prediction method. [0003] Existing heavy rainfall forecasting methods utilize heavy rainfall forecasting models to predict weather conditions in target areas. When training the heavy rainfall prediction model, this method usually uses a single type of data such as historical radar image data to train the model. The prediction accuracy of the generated model is low, and when predicting the weather conditions in different time periods in the target area, the same The heavy rainfall prediction model makes predictions, wh...
