Progress on Aviation Meteorological Forecast Technology System of National Meteorological Centre

Aeronautical meteorological support technology is one kind of the Integration technology which is supported by the most comprehensive technologies, the most technical difficulties and the highest technical requirements in weather forecasting technology. Based on the meteorological big data cloud platform and smart grid technology, The National Meteorological Centre has initially established an aeronautical meteorological advisory service forecast technology system for disaster relief, national defense security, civil aviation, and general aviation. This paper focuses on the most important airport refined weather forecasting for aeronautical meteorological service, airport approaching area and route dangerous weather forecasting technologies in this technical system. The important role of China Meteorological Administration big data cloud platform, intelligent grid technology, global and regional high-resolution numerical model, deep learning, multi-source data fusion and airport intelligence information on the construction of aeronautical meteorological technology system is expounded. The refined airport forecasting technologies based on smart grid for visibility, precipitation and wind are introduced. The methods of traditional extrapolation and deep learning of multi-source data fusion are used to out the severe convection short-term forecast integration technology; the potential forecasting technology of low-altitude wind shear in dangerous weather forecasting technologies such as turbulent, ice accretion and convection are developed based on Chinese global/regional numerical model. The ability and deficiency of Chinese intelligent grid technology system for aviation meteorological professional services are analyzed, and the future development of aviation meteorological professional service technology is expected.
