Research on the short-range forecast and warning method of strong convective weather for flight test

Test flight meteorological guarantee is different from military and civil aviation meteorological guarantee, mainly in terms of aircraft type, flight subjects, and guarantee mode, etc. Based on the above reasons test flights have more complex and diversified requirements for meteorological conditions, and at the same time, flying under dangerous weather conditions has high challenges for meteorological guarantee personnel in terms of psychological quality, technical level, communication ability and guarantee plan. By studying the strong convective weather affecting the test flight mission process in the past five years (2016-2020), we summarize the strong convective weather forecast and warning guarantee method, and use the fine grid 3-hour forecast from the European Centre for Medium-Range Weather Forecasting (ECMWF), Doppler radar of Xi'an station and satellite cloud maps to focus on the analysis of the squall line weather forecast and the whole process of test flight guarantee on June 13, 2020, to demonstrate the established The short-range forecasting and warning method and guarantee model were established to improve the strong convective weather forecasting and warning guarantee model and method, to realize the transformation from theoretical model to practical application, to lay a solid foundation for the strong convective weather process forecasting and guarantee capability, and to provide reference for future flight rehearsal guarantee under complex weather conditions.
