Weather forecasting method and device based on multi-scale numerical weather forecasting mode fusion

Abstract

The invention provides a multi-scale numerical weather forecasting mode fused weather forecasting method and device, and the method comprises the steps: obtaining a multi-scale numerical weather forecasting mode fused target forecasting factor according to atmospheric circulation forecasting data and convective weather forecasting data; and inputting the target forecasting factor into a pre-trained deep learning forecasting model to obtain a weather forecasting result. According to the invention, the forecasting factors of the numerical weather forecasting modes with different scales are fused and input into the pre-trained deep learning forecasting model to obtain the predicted weather forecast, so that the defect that the forecasting effects of weather systems with different scales cannot be considered at the same time in the prior art is overcome; according to the invention, fusion of numerical weather forecasting modes of multiple scales is realized, and the forecasting effect of weather systems of different scales is effectively improved.

Description

technical field [0001] The invention relates to the technical field of weather forecasting, in particular to a weather forecasting method and device for fusion of multi-scale numerical weather forecasting models. Background technique [0002] With the development of computer level and the progress of data assimilation technology, numerical weather prediction has become the core and foundation of current meteorological departments to make weather forecasts, and has an irreplaceable status and important role for other forecasting methods. At the same time, deep learning has also been widely used in the field of weather forecasting due to its powerful feature extraction capabilities. [0003] At present, according to whether the convective parameterization scheme is used to directly simulate the atmospheric convection process, the numerical weather prediction models can be divided into global numerical weather prediction models and convection-resolvable numerical weather predic...
