摘　　要：主要介绍河南省气象台2007年引进中国气象科学研究院研制的《新一代天气雷达灾害性天气警报和临近预报系统》的结构和产品,本地化参数设置和资料传输处理,以及在2007年汛期的业务使用情况。该系统充分利用新一代天气雷达基数据,除了可以显示常用产品外,还生成"逆风区识别"、"中气旋识别"、"暴雨回波识别"、"飑线识别"、"风暴识别"、"强冰雹识别"以及1到3小时"降水临近预报"、"回波外推预报"和"雷达雨量计联合估测降水"、"定量估测降水集成"等一系列业务应用产品,在强对流天气监测与预警中具有明显的指导和预警作用,是实际业务工作中不可缺少的工具之一。The paper introduced the structure and production, localization parameter setting, transporting processing of data and services of the system on disaster weather warning and nowcasting by new generation weather radar in the flood season of 2007. The system was developed by Chinese Academy of Meteorological Sciences and introduced by Henan Meteorological Observatory in 2007, which could not only display the commonly used production but also create a series of services production such as identification of reverse wind region, meso-cyclone, rainstorm echoes, squall line, storm and heavy hail, nowcasting of precipitation from 1 to 3 hours, extrapolation forecast of echoes, area rainfall using radar-raingauge and the consensus of estimating rainfall by fully using the base data of the new generation weather radar. Therefore, it has obvious guiding and warning function in monitoring and early warning the severe convection weather and is one of the indispensable tools in our practical operations.
