摘要
介绍了国内地质灾害预报预警方法研究及系统开发现状,阐述了河北省山区地质灾害气象预警系统的设计思路、系统构成、主要功能及特点。该系统利用河北省地质灾害区划信息、地理信息、气象观测和探测信息(稠密区域气象观测站降水、多种多普勒雷达产品、卫星云图、闪电定位等资料)、数值模式降水预报产品等,采用数理统计、天气动力学方法及计算机应用技术,可以方便快捷地生成预报预警产品。经2007年汛期业务应用证明,该地质灾害气象预警系统可以对地质灾害预报进行及时订正,减少空、漏报率。
The present situation of geological hazard forecasting and warning research and system development is introduced, and the design ideas, system components, main functions and features of the meteorological forecasting and warning system of geological hazards for the mountainous areas of Hebei Province is expounded. The design of the system is reasonable, considering the such information as the geological hazard regionalization, GIS data, meteorological observation （including intensive regional precipitation observation, Doppler radar products, cloud satellite images, lightning position, etc）, numerical forecasting products of precipitation, etc. Adopting the mathematical statistical, synopticdynamic method, and advanced computer technology, it is able to create forecasting and warning products conveniently. The operational application in the flood season of 2007 proved that this forecasting and warning system of geological hazards performed well with considerable accuracy and less no-hitting and false-hitting rates.
