Rainfall objective forecasting method based on numerical weather forecast and artificial intelligence

The invention belongs to the technical field of weather forecasting, and relates to a rainfall objective forecasting method based on numerical weather forecasting and artificial intelligence. The rainfall objective forecasting is carried out based on the numerical weather forecasting and the artificial intelligence technology, and the rainfall forecasting accuracy can be further improved on the basis of numerical forecasting. The comparison test of 24-hour rainfall forecast and 1-hour rainfall forecast of national ground observation stations in Shandong Province from April to September in 2020 shows that the 24-hour rainfall weather forecast score provided by the method is higher than that of numerical mode direct forecast in business, the relative error of 1-hour rainfall forecast is smaller than that of numerical mode forecast, and the method has good forecast advantages and high application value. 本发明属于气象预报技术领域，涉及一种基于数值天气预报和人工智能的降水客观预报方法。本发明基于数值天气预报和人工智能技术进行降水客观预报，可以在数值预报的基础上进一步提高降水预报准确率。通过对2020年4-9月山东省国家级
