Abstract :
The Thin-Wire Time Domain (TWTD) Code and the Waterloo Analysis and Design (WATAND) Code were combined into a new three-dimensional (3-D) time domain computer code. Based on the new computer code a 3-D time domain model of lightning was proposed. The lightning model was verified during the 1985 lightning season by measurements conducted at the CN Tower in Toronto. Using the new model, it is possible for the first time to correct the lightning current for the presence of towers and to predict the current distribution along a lightning channel.
