| 摘 要： | 利用新一代天气雷达资料分析闽东北地区夏季对流云的回波特征。分析表明:多单体合并对流云在生命史、回波高度、强度、尺度等方面都超过了单体对流云,其液态水总量也更大,自然降水条件和人工影响潜力都优于单体对流云,是夏季降水和人工催化的重要云系。分析得到对流云发展的不同阶段、不同高度层辐合辐散特点,为进一步研究夏季对流云结构和降水原理提供科学依据。通过对两个个例的天气形势分析,指出冷空气对对流发展有一定的激发作用。

| Abstract: | By using new generation weather radar data,the characteristics of convective cloud echoes in summer over the northeastern Fujian Province are analyzed.The results indicate that the lifetime,heights,intensities,and scales of multiple-cell convective clouds are large than those of convective cells;the natural precipitation conditions and the potentiality of precipitation stimulation are better.The features of convergence and divergence in different time and heights are analyzed.The results provide evidences for the further study of convective clouds and precipitation theory in summer.Convective clouds are key precipitation cloud systems in summer and important to artificial precipitation.Through analyzing the synoptic patterns of two cases,it is shown that the cold air can stimulate the development of convection. |
