Abstract

The invention discloses a highland severe convection weather short-term nowcasting and pre-warning system. A short-term nowcasting and pre-warning system is used for carrying out short-term nowcasting on the severe convection weather; a severe convection weather monitoring and forecasting system is used for monitoring the severe convection weather on the basis of meteorological observation materials; and a severe convection weather forecasting system is used for pre-warning and forecasting the severe convection weather by using the meteorological observation materials of an automatic meteorological station and the conventional meteorological observation materials. According to the highland severe convection weather short-term nowcasting and pre-warning system, a V-3Theda model of the severe convection weather is established to pre-warn the severe convection weather and distribute visual pre-warning information in time; a safety certification and authority management mechanism is provided for realizing the query, downloading, conversion and service of information under network environment in allusion to information service platforms of users with different authorities; and the forecasting level for the severe convection weather such as highland rainstorm, hailstone, snowstorm and the like is improved.

Description

technical field [0001] The invention belongs to the technical field of weather forecasting, in particular to a short-term nowcasting and early warning system for plateau strong convective weather. Background technique [0002] Strong convective weather such as heavy precipitation, hail, and blizzard in Tibet has an important impact on social stability, food production, and economic development in Tibet. The establishment of a short-term nowcasting and early warning system for such severe convective disastrous weather is of great significance. [0003] At present, there are few application systems for short-term nowcasting of severe convective weather over the plateau, and the key technology is formed around the application of multi-source meteorological information. The V-3Theda model is used to improve the forecast of strong convective weather such as heavy precipitation, hail, and snowstorms over the plateau. Forecast level. Contents of the invention [0004] The presen...
