Research On Application Of Area Numerical Prediction Technology In Airway Weather Forecast

Meteorological numerical forecasting plays a very important role in the aviation industry.Weather conditions can be accurately forecasted.For aviation business,not only can it increase economic benefits,but also it has a considerable positive effect in ensuring aviation safety.Today's regional numerical forecasting techniques are difficult to meet the requirements put forward by aviation.During the aviation weather forecasting process,the research on the weather forecast of the route is more scarce.In this paper,based on the regional numerical forecasting technology under the WRF model,a weather simulation of a special weather in Southwest China was conducted on January 27,2015.Combined with the actual airborne QAR data and AMDAR data,the simulation results are analyzed for correlation and judgment accuracy,and the simulation results under this mode are comprehensively evaluated.WRF-3DVAR is used to finely process the numerical prediction technology of the route region,and the experimental results have been analyzed and met the forecasting accuracy required by the aviation business.The innovation of this paper is to improve the traditional area numerical forecasting technology.Combined with the relevant information in the flight flight plan,the forecasted area will be specified to a specific position for the area around the route where the route is operating,so that the area numerical forecast is more applicable to the aeronautical meteorology field.The improvement of the area numerical forecast in this paper is more conducive to the application of this technology to the aviation weather forecasting business and the development of aviation weather forecasting products.It has a considerable positive effect on reducing the aviation accident rate caused by meteorological reasons as well as the flight return and reserve reduction rate,and also has a certain role in promoting the increase of airline profits.
