Abstract
A numerical model for a lightning channel that includes a multigroup treatment of radiative transport was used to calculate the optical output corresponding to an assumed current waveform. The calculation compares well with the experimental data that are available. The time development of the temperature, pressure, density, and electrical conductivity profiles across the channel were investigated, as was the energy balance for the process.Keywords
