对降雨电流(i)、降雨速率（R’）和电位梯度(P)进行了连续观测。根据Wilson的水滴离子捕获理论，Marshall和Palmer利用雨滴的大小分布（asi=2.12×10-6PhR ' 0.84-0.54×10-6PhR ' 1.05）获得了它们之间的定量表示，其中i给出了最大雨电流，Ph是云下雨滴充电区域的电位梯度。将计算结果与实测结果相结合，发现Ph与P的关系为：|Ph|=3P1.3，并讨论了上述结果与Simpson经验结果的关系。此外，还描述了雨滴在地面上的飞溅效应和雨流与势梯度之间的镜像效应的一些结果。
The continuous observations of the rain current (i), the rate of rainfall (R′) and the potential gradient (P) were made. Providing the Wilson's theory of ion capture by water drops, the quantitative representation between them is obtained using the size-distribution of raindrops by Marshall and Palmer asi=2.12×10-6PhR′0.84-0.54×10-6PhR′1.05, where i gives the maximum rain current and Ph is the potential gradient in the charging region of raindrops below the clouds. Applying the calculated result to the measured ones, it is found that Ph relates to P by |Ph|=3P1.3 The relation between the above results and the Simpson's empirical ones is discussed. Further, some results in regard to the splashing effect of raindrops at the ground and to the mirror-image effect between the rain current and the potential gradient are described.
