The invention provides a weather forecasting method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining a first weather actual value of a current date; performing forward integration on the first meteorological actual value of the current date to obtain a future date meteorological predicted value; performing reverse integration on the future date weather prediction value to obtain a current date weather prediction value; and adjusting the formulas of the forward integral and the backward integral to minimize the error value between the first meteorological actual value of the current date and the meteorological predicted value of the current date, and taking the meteorological predicted value of the future date as the weather predicted value. According to the technical scheme provided by the invention, the weather forecast is carried out through the time integration mode of the forward integration and the reverse integration, and the error value between the first weather actual value of the current date and the weather forecast value of the current date is minimum by adjusting the numerical values of the forward filtering and the reverse filtering to control in the direction of error reduction; therefore, the errors of medium-term and long-term weather forecast are reduced, and weather forecast stability is improved.
Description
technical field [0001] The present application relates to the technical fields of cloud technology and meteorological data analysis, and specifically relates to a weather forecast method and device, electronic equipment, and a computer-readable storage medium. Background technique [0002] Numerical prediction has experienced a long development, and numerical prediction has made great progress. The accuracy of the forecast is very accurate at the early stage of the forecast, and with the increase of the forecast integration time, the forecast accuracy decreases obviously with time in the middle period of the forecast. However, the forecast accuracy drops so significantly in the later period of forecasting that the accuracy in the later period of forecasting cannot be used. Theoretical research shows that the longest forecasting time of numerical forecasting cannot exceed 14 days. At present, most of the numerical forecasting forecast time length is within 14 days. In the ...
