摘要:

突发性强灾害天气预警系统”以WWW为平台,融贯多种天气预报新技术,为各类用户提供了崭新的预报视角和技术含量较高的预报产品;产品包括强对流指数诊断、基于卫星和雷达的外推产品,中尺度数值模式预报产品,以及基于“综合叠套技术”给出的强天气展望和强天气临近概率预报产品等。通过近几年部分省市业务化运行检验,证明该系统整体自动化程度高,运行稳定,其提供的综合预警产品能有效地为暴雨等强对流天气提供预警信息,提高了暴雨等强天气的预报预警服务质量。

关键词: 预警系统灾害天气强对流指数综合叠套物理耗散    
Abstract:

A brief introduction is given to the Early Warning System for Severe Weather Events (EWSSWE) with emphasis on its main functions and the key technologies adopted as well as the applications. Using WWW as its platform, EWSSWE generates and demonstrates a series of forecast and early warning products, including the diagnoses of the severe convection indexes, extrapolative products based on satellites/radars, meso-scale model prediction outputs as well as probability products of severe weather outlook and early warning via "the composite nesting method". The EWSSWE generates rapidly the forecast/warning products that can be called remotely and displayed artistically through the internet with automation and stable operation. Its preliminary applications to the operational services show that the EWSSWE is able to improve the local weather forecast accuracy and thus becomes a powerful tool with the warning products of quality.

Key words: Early warning system    Disastrous weather    Severe convective parameters    Composite nesting method    Physical dissipation.
