【摘要】 针对山东飞机人工增雨作业的实际情况，分析了山东沿海地区的降雨特征，统计了沿海云层的宏观物理量，分析了莱州湾、黄海北部和东南沿海３个地区云与降水的关系，对主要降雨天气系统计算了其降雨效率及增雨潜力，增雨潜力在４２．５５％—６８．７９％。通过对天气系统中水汽垂直分布的分析，为飞机在山东沿海地区增雨作业最佳催化层次的选择提供了依据。更多还原

【Abstract】 The characteristics of rainfall,macro physical parameters of cloud and the relations of cloud and rainfall are studied.The precipitation enhancement potencies of main weather systems range from 42 55% to 68 79%.Elaborated,also is the possibility of exploiting cloud water resources by rain making with aircraft.The scientific verification for cloud seeding in the coastland of Shandong province are provided by the analysis of water vapor vertical distribution.更多还原
