  cloud droplets
The advantage of poorly soluble substances over commonly used soluble salts is that the finely dispersed part of the spectrum of the poorly soluble ACN does not deliquesce and so is not involved in the formation of cloud droplets.
      
In this case, no "overseeding" phenomenon is observed, which, for soluble substances, manifests itself in an increase in the concentration of cloud droplets with a large ACN concentration.
      
It is shown that cloud seeding with additional particles whose sizes exceed the characteristic size of atmospheric condensation nuclei leads to a decrease in the concentration of cloud droplets and an increase in their sizes.

As the cloud structure is usually fluctuating, it is important to study the growth of the droplets under gravitational coalescence in such an environment. In this paper the growth rate of cloud droplet is calculated under the consideration of the fluctuation of the water content. The result obtained differs considerably from that obtained for the case without such fluctuation, and seems in better accord with the condition observed in the atmosphere. The growth rate is now much greater and the precipitation elements may even develop quickly from a group of small droplets of small dispersion in a cloud in a state of not intensive fluctuation.

云雾中的气象要素和云雾物理量经常有着起伏,因此研究重力碰并在这种起伏条件下如何使云滴生长,从而形成滴谱,是很必要的。本文对云中小水滴浓度(或含水量)有起伏时的云雾滴生长进行了计算,得到了云滴的一种理论分布。由此可以看出,在起伏条件下,云滴生长是比较快的。在比较短的时间和比较薄的云中有可能形成相当大的云滴,即半径50μ乃至100μ以上的云滴。因此在均匀条件下,凝结生长和重力碰并增长中的所谓“生长障碍”区(云滴半径在20—30μ左右)也就不存在。

Taking consideration of the fluctuation in the vertical current, it is pointed out that the precipitation element Will form more easily in a shallow warm-cloud. Under the assumption that the frequency distribution of the vertical current is Gaussian, the growth rate of the cloud droplet is calculated for a simplified cloud model. The result shows that even in a cloud with 1 km thickness the precipitation elements of radius greater than 100 μ could be formed under average condition.

本文中考虑了云中垂直气流的湍流起伏,来計算云滴的碰并增长.发現在这种上升气流有起伏的环境下,同样大小的云滴在云中可以长成不同大小的較大云滴,包括降水胚滴和降水微元(雨滴),从而对暖性薄云如何形成降水給出一个此較合理的解释。
