本文采用多因子综合相关概率法、双参数点聚图法,综合对六盘山区151个暴雹个例进行了统计分析,找出了六盘山区雷达识别冰雹云的定量综合指标。结果表明,综合指标达到2.9时,识别雹云的成功率达92.1%。

In this paper, 151 hailstorm cases in Liu-Pan mountain area are studied by using multiple-factor correlation probability method, two parameter scatter diagram method. Quantitative indexes recogniting hail cloud by using weather radar are determined. The results show accuracy is 92.1% when the comprehensive index is equal to 2.9.
