广州雨滴尺寸分布

The Distributions of Raindrop Sizes in Guangzhou

本文主要介绍利用激光雨滴谱仪在广州开展的雨滴尺寸分布测量结果。按照降雨率的数值大小，将雨分为暴雨、广延雨和小雨三类，分别给出所属雨类的雨滴尺寸的实测分布和拟合分布曲线，并将拟合分布曲线和Ｌ—Ｐ、Ｍ—Ｐ、Ｊｏｓｓ分布曲线进行了对比分析。

In this paper,measured results of the distributions of raindrop sizes with laser raindrop spectrograph in Guangzhou are presented. With the values of the rain rate the rain are claseified to thunderstorm rain, widespread rain and light rain, among which both the measured and fitted distribution curves with the comparison among the fitted distribution curves, M- P,L- P and Joss disttibution curves are given. Figures 1～ 3 are the examples of the raindrop size distribution of thunderstorm, widespread and light rains in Guangzhou, resistively. The various rain rate curves of measured, fitted, M - P, L - P and Joss distributions are given in Figures 4-6. Figures 4-6 shows the measured curves are in good agreement with the fitted ones.
