Electric Field Changes due to Tilted Streamers in the Cloud Discharge

[摘要] A comprehensive calculation of the electric field changes was made for the tilted streamer model in the cloud discharge, in which the streamer proceeds with various angles from the cloud charges. The field changes calculated as a function of distance from the cloud charge to the observer are shown systematically for the positive and negative streamers in the positive dipole. The result shows quite different features from the case of the vertical streamer. The observed electric field changes due to cloud discharge may be interpreted more clearly with this tilted streamer model.
