Development and Construction of the Supporting Platform for National Severe Convective Weather Forecasting and Service
摘要
Abstract
The focus of national severe weather forecasting is transforming from short-range forecast to the pattern of the coexistence of short-range forecasts and short-time forecasts.For the requirements of severe weather forecast techniques and service,this paper presents the development of national severe weather integrated platform.Based on the core requirements of meteorological data organization and plotting,the development of data analysis system,meteorological auto-plot system and WEB search and display system are developed.The data analysis system,as the core of the whole platform,integrates various data,including muti-sourcc monitoring data and mcsoscale NWP model forecast and global NWP model forecast,and develops the data-processing technology for severe weather monitoring and nowcasting,short-range foreeast and short-time forecast.The key technology includes:starting from considering the unstable energy,water vapor,uplift,and vertical wind shear,the classified short-range analysis and prediction technology summarizes conceptual models for different types of severe weather.The severe weather tendency forecast part guided by the severe weather condition analysis,generates a classified severe weather forecasting model and products.The short-term forecast test part integrates the applications of mososcale NWP,ensemble prediction,meso-analyses and sounding analysis,and highlightes the seamless link between the observa tion in the past 3 h and the prediction of the future 12 h.Based on the existing convective system monitoring technologies,the auto-alarm products of radar features,severe weather events,convective indices and alarm signals are developed to improve the convective weather monitoring and nowcasting technology.Meteorological auto-plot system includes the functions of data analysis,automatically plotting,etc.In the term of service,the WebGis tech is applied to share the national products to the county-level weather stations and vice versa.关键词
