Abstract :
We consider dynamics of the lightning-channel corona sheath that is implicitly specified by lumped-current-source lightning return-stroke models. Two slightly different corona models for prediction of charge motion in the corona sheath are proposed. Both models can be viewed as generalizations of the model proposed by Maslowski and Rakov (2006) and are in agreement with measurements of the horizontal (radial) electric field component made in the immediate vicinity of triggered lightning channel.
