摘要
Kessler,Berry,Simpson,Cotton,胡志晋等提出了各自不同的云雨自动转换率公式,用参数化的方法处理云雨自动转化过程。本文在二维时变的暖积云降水模式中,使用Kessler,Berry,胡志晋三种云雨自动转换公式,对不同强度的暖积云进行了数值计算。
In this paper three formulas of autoconversion rate were used to calculate the precipitation using a two-dimensional and timedependent model of warm cloud.The result shows that the differences in total precipitation are small(less than 6%).But it becomes larger in weak warm rain process,about 20%,with maximum value less than 82%.It is found out that the autoconversion rate is not a sensitive factor in numerical simulation of warm cloud rainfall.
