On the Freezing Electrification of Freely Falling Water Droplets
The electrification of freely falling water droplets due to freezing was measured in a laboratory experiment.
When distilled water was used for specimen, the frequencies of positive and negative electrification were nearly the same, while the positive electrification was predominant in case of water melted from fresh natural snow.
It was concluded that the electrification of natural ice pellets is provided by the ejection of charged splinters with a diameter of a few micrometers at the end of freezing state.
