检验了云和雾中有关液滴尺寸分布的实验数据，结果表明，在许多情况下，该公式可以表示液滴的尺寸分布
式中，F是空气中液态水的比例，由直径小于x的水滴组成。常数a随云中液态水含量的增加而增加。目前还不清楚是什么决定了常量n的值，但合理的平均值约为3.3。
结果表明，在n值未知的情况下，如果液滴大小分布可以用上述方程描述，则中值体积直径是描述云粒子平均大小的最合适参数。
Experimental data relating to drop-size distribution in cloud and fog are examined and it is shown that in many cases the size distribution can be represented by the formula
where F is the fraction of liquid water in the air comprised by drops with diameter less than x. The constant a increases with the liquid water content of the cloud. It is not clear what governs the value of the constant n but a reasonable mean value is about 3.3.
It is shown that, if the drop-size distribution can be described by the equation quoted above the median volume diameter is the most suitable parameter for describing the average size of the cloud particles when the value of n is not known.
