摘　　要：风雨影响评估是热带气旋预报预警服务中的一项重要工作,而热带气旋风雨影响的历史气候数据是支撑这一工作的重要依据。以深圳为例,提出了建立热带气旋数据库系统的技术思路,该系统实现了以下几种功能:1)热带气旋数据的后台自动入库;2)关键区和相似离度相结合的相似台风的自动检索和风雨影响分析;3)直观展示广东沿海各市登陆的热带气旋的风雨影响气候概况;4)热带气旋风雨影响等级的自动提示。通过该系统,预报员可以高效、快速地查询历史相似路径或相同登陆点的热带气旋风雨影响情况,从而为分析当前热带气旋可能造成的风雨影响评估提供参考依据。Assessment on the wind and rain hazards during the landfall of tropical cyclone（TC）is an essential task in the weather forecasting and warning service,and the climate data collected during the passage of TC are important to support this job. Taking Shenzhen as an example,a TC climate database system and the technical thoughts used to establish the system are introduced. The system has the following functions：1） Meteorological data on TCs can be automatically collected and stored into the database;2）The system can help to pick out historically similar TCs based on the key area checking combined with the TC tracks deviation checking,and consequently help to evaluate the wind and rain hazards of TCs on Shenzhen;3）The system can visually illustrate the impacts of different TCs landing at different cities of Guangdong province;4） The system can automatically prompt forecasters the hazard level of different TC. Through the platform,forecasters can quickly and efficiently obtain the information on the wind and rain hazards of the TCs with similar paths or landfall points,which will help to evaluate the wind and rain hazards possibly induced by current TC.
