Abstract

The invention relates to a weather forecast method and device based on a numerical mode, equipment and a storage medium. The weather forecast method based on the numerical mode comprises the steps ofobtaining to-be-processed data corresponding to a forecast grid, wherein the to-be-processed data is determined according to initial field data corresponding to the forecasting grid; inputting the to-be-processed data into a numerical forecasting model, and controlling the numerical forecasting model to output a plurality of model integration results according to a plurality of integration step lengths, wherein the plurality of integral step lengths are not equal; determining forecast field data corresponding to a target forecast step length based on an average value of the plurality of modelintegral results, wherein the integral step length is a factor of the target forecast step length. By adopting the method, truncation errors caused by a numerical mode in numerical weather forecast can be reduced, and computing resources can be saved.

Description

technical field [0001] The invention relates to the technical field of weather forecasting, in particular to a numerical model-based weather forecasting method, device, equipment and storage medium. Background technique [0002] Numerical weather prediction refers to solving the equations of fluid dynamics and thermodynamics describing the weather evolution process through large-scale computer numerical calculations under certain initial and boundary value conditions based on the actual conditions of the atmosphere, and predicting the state of atmospheric movement for a certain period of time in the future. and methods of weather phenomena. Numerical model is a necessary tool for computing numerical weather prediction, and time integration of numerical model is the key to forecasting weather. [0003] Numerical integration methods based on differential equations will bring truncation errors. In many cases, it is difficult to obtain accurate solutions for mathematical models...
