摘　　要：20 0 1年和 2 0 0 2年 7～ 9月利用福建省建阳市和龙岩市二部新一代天气雷达对福建夏季对流云进行系统的观测。通过对观测资料的统计分析和实例分析得到 :不同类型福建夏季对流云的生命史、尺度、强度等特征 ;多单体合并对流云液态水总量最大 ,发展—成熟阶段平均值达 4 .8× 1 0 9kg ,是福建夏季对流云中最重要降水云型 ;对流云发展的不同阶段 ,不同高度层辐合辐散特点。这些结果为进一步研究夏季南方对流云结构、降水原理提供科学依据。The CINRAD radar was applied to observation of convective clouds in summer in South China, and the observation data was analyzed. According to the results: (1) The features of various convective clouds, including the lifetime, scale and intensity, are revealed. (2) The cloud liquid water amount of multiple cell convective clouds is the largest; its average value at the growing maturing stage can reach 4.8×10 9 kg. The kind of clouds is most important to precipitation. (3) The features of convergence and divergence in different time and height are analyzed. The results provide evidences for farther study of the structure of convective clouds and precipitation theory in summer in South China.
