On the effects of channel tortuosity on the close electromagnetic fields associated with lightning return strokes [PDF]
arXiv, 2010 The electromagnetic fields associated with tortuous lightning channels are usually characterised by a pronounced fine structure. This work investigates and quantifies the effects of channel tortuosity on the return stroke electromagnetic field shapes in the close lightning environment (the range up to 100m from the lightning striking point).
