An extension of the engineering return-stroke models for lightning strikes to tall structures
that takes into account the presence of possible reflections at the return-stroke wavefront
and the presence of an upward-connecting leader is presented. Based on the approach
proposed by Shostak et al., closed-form, iterative solutions for the current distribution along
the channel, and the strike object are derived. Simulation results for the magnetic fields are
compared with experimental waveforms associated with lightning strikes to the CN Tower …
