摘　　要：以中国气象局气象探测中心提供的2007—2008年灾害性天气个例档案为基础,对CINRAD/SA雷达风暴识别跟踪和中气旋产品做了定量评估,同时就评估结果与美国同类产品做了对比。结果表明,风暴识别与跟踪产品基本能满足临近预报的需要,但存在漏识别和错误跟踪现象,且30 min以后单体位置预报误差较大。中气旋产品评估结果与美国产品差异不大,基本能自动识别风暴涡旋,但存在漏报,且虚警率较高。In order to get a relatively objective assessment for the storm cell identification and tracking （SCIT） and the mesoeyclone detection algorithm （MDA） products＇ application in China, and then to pro- vide reference of the products for future use, the performance evaluation of two kinds of products on the current business has been done based on the 2007--2008 disaster weather case archives offered by CMA Meteorological Observation Centre. The results of the evaluation are compared with the United States＇ and show that the SCIT products can meet the basic needs of nowcasting, but the leak detection and error tracking exist, and when the lead time exceeds 30 min, the location prediction error can be big. The per- formance evaluation of MDA products can be considered similar to the United States＇, and basically can automatically identify the storm vortex, but there are still some missings, and the false alarm rate is high.
