中文摘要: 分析安徽地区春夏季冰雹云雷达回波特征，对人工影响天气防雹作业有重要意义。根据2002—2013年间安徽省地面降雹资料，结合合肥新一代天气雷达(CINRAD)探测资料，使用Storm Cell Identification and Tracking (SCIT)算法设计风暴识别、追踪程序，得到3—8月59站次的降雹过程。统计分析冰雹云回波强度、回波高度、单体VIL等特征信息，结果表明：6—7月安徽地区降雹概率最大，1日中15—18时降雹概率最大。安徽地区春夏季冰雹云回波强度至少为55 dBz，大多数为60~70 dBz，单体VIL至少为30 kg·m-2，大多数为40~80 kg·m-2。单体VIL与最大反射率的变化趋势比较一致，最大值往往出现在降雹时间附近。安徽地区春夏季冰雹云回波顶高平均13.6 km，30 dBz风暴顶高平均12.1 km，最大回波顶高达17 km以上。

Abstract:Analysis of the hail echo artificial in Anhui in spring and summer is important for hail prevention. By using the hail data collected in Anhui during 2002-2013, CINRAD data, the Storm Cell Identification and Tracking (SCIT) algorithm, we got 59 hail processes from March to August and analyzed statistically the echo intensity and height of hail clouds, and VIL. The results show that hail probability is the greatest in June and July, especially in from afternoon to evening (15:00-18:00 BT). Over the Anhui Region, hail echo intensity of spring and summer is at least 55 dBz, mostly is 60-70 dBz, VIL is at least 30 kg·m-2, mostly is 40-80 kg·m-2. The varying trend of VIL is similar with the maximum reflectivity, and their maximum values tend to occur near the onset time of hail. The average echo top of hail storm is 13.6 km in spring and summer, average top storm height of 30 dBz is 12.1 km and the maximum echo top height is above 17 km.
