摘要
强对流天气是严重危害人民生活的危险性天气,特别是对于空中飞行有重大影响。目前,国内外主要的临近预报技术包括利用雷达资料的雷暴识别和跟踪技术、利用卫星资料的强降水估计,概率预报技术、概念模型和数值模式预报技术等。本文重点介绍近年来发展起来的强对流天气临近预报方法和主要业务系统,分析了临近预报技术中存在的主要问题并对未来发展趋势进行了展望。
Severe convective weather does serious harm to people＇ life,particularly for flying.At present,main nowcasting technologies comprise identification and tracking technology based on weather radar data,strong precipitation estimate based on satellite data,probability prediction technology,the conceptual model and numerical model prediction technology and so on.This article introduced with emphasis on the severe convective weather nowcasting method and main operational system which were developed in recent years,analyzed the existing problems and forecasted the development trend.
