本文对泰山和新安江等地层养云的一些云滴谱和雨滴谱进行了计算。对小云、滴、大云滴和雨滴谱的谱分布用同一种形式的分布密度函数N=AN₀exp(-ad+bd²-cd³)来表示。观测和计算的谱分布吻合得较好,其相关系数均大于0.93,显著性水平α=0.001。计算得到的平均直径、平均立方根直径、含水量和总浓度等与观测值也都比较吻合,说明本文给出的云中水凝物粒子谱分布有一定的代表性。

The cloud and the rain drop size distributions in stratiform clouds which are in the region of Mount Tai and Xinan River are calculated . The cloud droplet and drop (d≥80μm) and the raindrop size distributions are fitted by using N=AN₀exp(-ad+bd²-cd³). The observational and calculated results are well matched. The correlation coefficients are bigger than 0.93 and the significance level is 0.001. The calculated mean diameter, mean cube-root diameter, liquid water content and total concentration are all well matched with observational results. It has been proved that the water drop size distribution is representative.
