| 摘 要： | 使用Cinrad／CD多普勒雷达资料分析了在流域交汇处的东风湖地区湖面大风的产生原因和降雹的RHI（range—height indicator，距离高度显示器）特征。对鸭池河流域范围内两个雹云回波移动演变个例的分析表明，具有多个小尺度对流中心的雷暴自不同河段跨河后有不同的发展趋势，具有利已路径的特性。 |

| Abstract: | The phenomenon that there exists obvious difference in times of hail shooting between the eastern and western side of the Yachi River is first revealed using observational data, and the difference is found to be associated with down-slope wind, mesoscale leeward slope low-pressure and environment heating. The reason of lake surface high wind and the range-height indicator （RHI） echo character of hall shooting over the Dongfeng lake area at river confluence reaches are analyzed. The echo analysis of the motion and evolution of two hail storms on May 10,2004 in the Yachi River basin shows that storms with multiple convection centers of small scale exhibited different development trends when crossing the river at different river reaches, and hail storms always moved along a route advantageous to their development. This may prove the mechanism for the motion and evolution of hall storms in the Yachi River basin. |
