| 摘 要： | 利用湘西北张家界市2005年夏季的人工防雹增雨作业资料和地面降雹资料，分析冰雹云的雷达产品特征，发现使用小型车载雷达可以很好地弥补多普勒雷达常规业务产品中垂直剖面产品方面的不足，并归纳总结出了湘西北山区夏季冰雹云的1个先兆特征综合定性指标和4个雷达定量判别指标。实践表明，综合运用定性和定量指标可以快速准确提前识别冰雹云，有利于早期作业，是人工防雹作业获得成功的关键因素。

| Abstract: | Based on the data of weather modification and hailfall at Zhangjiajie in the northwest area of Human Province in the summer of 2005, the radar echo characteristics of hail cloud are analyzed, and the results show that a small mobile radar can have more RHI profiles to supply a deficiency far from Doppler radar in hail-preventing activity, One qualitative and four quantitative identification indexes for the hail cloud identification are found, and with the indexes the hail cloud may be rapidly and accurately distinguished. |
