中文摘要: 该文根据1989—1990年夏、秋在湖南所获的45块自然积云和催化积云地面雨水温度、环境气温、雨量以及部分雷达资料进行了统计和个例分析。结果表明:催化积云雨水温度比自然积云雨水温度低,平均低0.8℃;催化积云雨水温度大多数较环境气温低,平均低2.O℃,最大低2.3℃。
Abstract:Rainwater temperature differences of natural and seeded clouds are analysed using method of atatistical and some ceaes based on the data of rainwater temperature, environmental air temperature, rain amount and data of radar echoes from 1989 to 1990. The results are: 1)the rainwater temperatures of seeded cumulus are lower than that of natural ones. The mean of the differences is 0. 8℃ ,2)rainwater temperatures of most seeded cumulus are lower than the environmental, air temperature. The mean value of difference between both is 2. 0℃ and the maximum is 2. 3℃.
