【摘要】 利用 1 988～ 2 0 0 0年 7～ 9月南昌、建阳、长沙三站探空资料及同期地面和 50 0hPa天气图与降雨量资料等 ,对照 1 988～ 2 0 0 0年 7～ 9月南昌 (建阳、长沙 71 3雷达站部分资料 )“71 3”雷达站回波素描图进行统计分析 ,得出南方夏季对流云回波的顶高、强度、性质等参数变化规律与主要特征 ,从宏观上了解影响南方夏季对流云回波参数等特征量的变化规律 ,为南方各省人工影响天气作业提供科学依据。更多还原

【Abstract】 The conventional radiosonde data from Nanchang, Fuzhou, Changsha from July to September, 1988 to 2000 are used and analyzed, compared with the echo images from the Nanchang 713 radar station (and parts of the data from Fuzhou and Changsha radar stations) at the same time period. The results reveal the variation regularities and major characteristics of the top, intensity, nature, etc. of summer convective cloud echoes in South China. These are helpful to the understanding of the variation regularities of the parameters influencing summer convective cloud echoes in South China, and provide a scientific basis for the operation of rain enhancement in the southern provinces.更多还原
