| 摘 要： | 在对流性天气过程中，回波的合并往往容易引发强对流的产生和发展。本文针对2004年7月6日发生在浙江中北部到舟山沿海一带的一次强对流天气过程，利用舟山新一代天气雷达资料，对此次天气过程中出现的两次回波合并过程进行分析。结果表明：此次天气过程中出现的两次强对流天气都与回波的合并有密切的关系；最强烈的天气最有可能出现在回波即将合并到完全合并之间。

| Abstract: | During the convection weather, the combination of echos will normally generate strong convection. According to the strong convection weather happened on July 6,2004 at the middle-north part of Zhejiang Province, the article analyzes the two conbinations of the echos appeared in this weather by new weather radar data in Zhoushan City. The analysis shows that the two strong convection weather courses have close relation with the conbination of the echos. The severe weather most probably occurs between the combination being starting to the complete combination of the echos. |
