Abstract
Geometry of a lightning return-stroke channel influences the associated electric and magnetic field waveforms. Influence of the channel geometry in the larger scale on field waveforms is investigated through numerical electromagnetic analysis by using an electromagnetic model of lightning channel with the help of NEC-4. The geometry of the channel model is determined based on the observation of natural lightning by a lightning mapping array (LMA).
