Embodiment Construction

[0042] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0043] The WRF (Weather Research and Forecasting Model) model is a unified mesoscale weather forecast model jointly developed by the National Center for Environmental Prediction (NCEP), the National Center for Atmospheric Research (NCAR) and several universities, research institutes and business departments.

[0044] The present invention implements WRF regional model design, European numerical forecast and WRF model product integration, and carries out probability distribution correction and statistical correction of wind field based on probability distribution characteristics and sounding actual conditions, so as to realize high-altitude wind forecasting of 80 layers of 250m below 20km . This method is suitable for hi...

Abstract

The invention relates to a short-term forecasting method for high-resolution high-altitude wind, and belongs to the technical field of forecasting of high-resolution high-altitude wind in spaceflight meteorological support. Aiming at the requirements of forecasting and guaranteeing high-resolution high-altitude wind in spaceflight meteorological guarantee, 0.25-20km per 250m layered high-altitude wind forecasting is realized by utilizing an European mid-term numerical forecasting product and Beidou navigation wind measurement data through methods of WRF mode design, high-altitude wind mode product fusion, wind field probability distribution correction, statistical correction and the like. Through the method, layer-by-layer high-altitude wind forecasting can be realized, the accuracy of layer-by-layer high-altitude wind forecasting is improved, and the method is suitable for high-resolution high-altitude wind forecasting.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a short-term forecasting method of high-resolution high-altitude wind. Background technique [0002] Upper-altitude wind is an important factor for aerospace meteorological support. When a launch vehicle passes through the atmosphere, the wind load brought by high-altitude winds will affect the flight attitude of the rocket and have a certain impact on the structural reliability of the rocket. my country's new generation of launch vehicles has put forward higher requirements for upper-altitude wind meteorological guarantee, and the upper-altitude wind forecast is more precise. There is no related research to solve this problem. The upper-level wind forecasting method proposed in this paper can solve this problem well. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is how to provide...
