哈尔滨地区春夏季降水微结构特征

Microphysical features of precipitation in spring and summer in Harbin

摘要:

为了研究大气水资源本底分布特征,本文提供人工影响天气潜力和背景依据,采用PMS公司生产的GBPP-100型地面雨滴谱仪,取得哈尔滨地区1999年春夏季积雨云、积层混合云和层状云27次降水资料,分析了三类降水云雨滴微结构参量及其演变,并使用线性回归和逐步判别,对Γ分布参量n0、λ和μ的线性关系进行统计计算,得出了-些有意义的结果。

Abstract:

In order to study the characteristics of natural resources of water in the atmosphere,precipitation in Harbin from May in 1999 was observed 27 times with GBPP 100 produced by PMS Co..In this paper,precipitation data are analyzed to obtain spectrum parameters and their evolution features.Linear and stepwise regression are also used to make a statristical analysis on the linear relationship among the spectral parameters in Γ distribution.
