Charge Deposition on Ice Particles by Positive Streamers

[摘要] The paper describes a laboratory study to investigate charge deposition by propagating positive streamers on ice particles. A variety of ice samples similar to those present in natural thundercloud was used in this study. It was found that the deposited charge increased with the ambient electric field showing an enhancement in the streamer tip charge. Some possible implications of the results to thundercloud are discussed.
