Meteorological element forecasting method and system

Abstract

The invention discloses a meteorological element forecasting method and system, belongs to the technical field of meteorological forecasting correction, and solves problems that, in the prior art, a traditional mode output statistical forecast cannot obtain a nonlinear relationship, real-time updating cannot be realized due to slow calculation. According to the meteorological element forecasting method and system, historical statistics is carried out on forecast data of one or more modes, historical meteorological correlation between the fixed station mode forecast data and the actual observation data is acquired, the characteristic relation of mode elements is optimized, multiple meteorological factors are considered, a characteristic factor relation network is effectively constructed, synchronous prediction is achieved, mode data correction is achieved, statistical correction of the average wind speed, the highest temperature, the lowest temperature and rainfall of a fixed station can be achieved on the basis of the framework, and prediction accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of weather forecast correction, and more specifically, to a weather element forecast method and system. Background technique [0002] Refined weather forecasting business is the general trend of global forecasting business development. With the development of economy and the progress of science and technology, the demand for refined weather forecasting is becoming stronger and stronger. Due to the continuous expansion of the forecast objects involved in refined forecasting, the gradual extension of the forecast time limit, and the deepening of the refinement of the forecast space, it is difficult for forecasters to complete the production of refined forecasts according to traditional conventional forecasting methods. [0003] With the development of numerical forecasting and computer technology, more space is provided for refined weather forecasting. The available timeliness of numerical prediction products...
