摘要：

通过对合肥多普勒天气雷达2003～2006年逐年7月份回波资料的普查，统计和总结了安徽大别山地区对流云的合并规律，并对一次典型的对流云合并过程进行了实例分析。结果表明：(1)在影响安徽的诸多天气系统中，华北低槽型天气背景下大别山区发生对流云合并的几率最大。(2)对流云合并普遍发生在午后时段。(3)对流云合并后，雷达回波面积增大的概率在70％以上，回波强度增大的概率为66.3％，生命史主要集中在90～240 min。

Abstract:

By means of investigating the echo data on each July from 2003 to 2006 observed by Doppler Weather Radar in Hefei, the merger regulation of convective cloud in Dabie Mountains was statistically summarized, and a typical merger process was analyzed. The results show that: (1) According to many synoptic systems affecting Anhui, under the background of the low trough of North China the probability of merger in Dabie Mountains is maximum. (2) The merger generally occurs during the afternoon. (3) After the merger, the development probability of radar echo is more than 70% in area and 66.3% in intensity; the lifetime mainly concentrates on 90~240 minutes.

Key words: Doppler weather radar; the merger of convective cloud; Dabie Mountains
