对单个空气雪粒电荷的测量表明，它们在正值和负值之间大致对称分布。然而，大多数小电荷是负的，而大多数大电荷是正的。正（或负）电荷的大小往往遵循对数正态分布。降水所携带的净电荷的符号与大气电位梯度的符号之间的镜像关系通常被发现成立，但也注意到一些例外。然而，即使在特殊情况下，大气势梯度的变化也会影响电荷的分布。
Measurements of the charges on individual airborne snow particles showed that they were distributed approximately symmetrically between positive and negative values. The majority of the small charges were negative, however, and the majority of the large charges were positive. The magnitudes of the positive (or the negative) charges tended to follow a log-normal distribution. The mirror image relationship between the sign of the net charge carried by precipitation and the sign of the atmospheric potential gradient was generally found to hold, but some exceptions were noted. Even in the exceptional cases, however, changes in the atmospheric potential gradient affected the distribution of charges.
