Based on weather radar, ground and sounding data, NCEP reanalysis data, FNL Numerical forecast products, the classification and identification technology of severe convective weather and short-term near forecast technology is adopted to carry out the research on storm approaching forecast, severe convective weather classification early warning, and severe storm potential diagnosis based on numerical prediction, to obtain 0-2 hours real-time determination of severe precipitation, thunderstorm, gale, hail and other disastrous weather in Dali, Lijiang, Xishuangbanna and other plateau mountain areas and surrounding areas. The forecast products and 0-12 hour severe convective weather potential forecast products are used to establish the operational airport short-term severe convective weather prediction system. Through the test, it is proved that the forecast system has good forecast and early warning ability of severe convective weather, which can meet the operational requirements of the airport.
