近30a台湾非台风暴雨研究回顾

Non-typhoon heavy rain research in Taiwan for the past 30 years:A review

从1987年开始,台湾暴雨研究进入一个新纪元,由早期定性描述分析进入定量计算与模拟,其中包括新观测设施的建设与数值天气预报系统的建立。近年来,随着全球气候变暖,台湾极端降雨事件有所增加,其中不少极端降雨事件是由非台风暴雨所致,往往给当地社会经济和人民生命财产造成严重影响,这就迫切需要不断提高强降雨定量预报业务水平。本文通过对近30 a台湾在非台风暴雨研究发展方面取得的主要进展的回顾,重点介绍了台湾气象部门为了提高强降雨定量预报业务水平所做出的努力,同时对未来台湾非台风暴雨研究规划与方向作了简要介绍。

In this paper,non-typhoon heavy rain research in Taiwan for the past 30 years is reviewed.Since 1987 TAMEX experiment,Taiwan heavy rain research and forecast operation have been experienced a significant change,i.e.,from qualitative description transfer into quantitative analysis and simulation.Many new measurement instrumentations and numerical weather prediction systems have been installed.Due to great challenge caused by climate change and frequent occurrence of extreme weather events,in order to provide timely information for emergency response and disaster risk reduction,technology development on quantitative precipitation forecast(QPF)has become world-wide common requirements.In this paper,efforts from Taiwan meteorology community to strengthen the knowledge of basic understanding of heavy rainfall events and to improve the forecast capability are reviewed.
