Return stroke lightning channel model
Abstract
Transmission line theory is used to model the current waveform in a lightning flash to ground. By adjusting the resistance, inductance, capacitance, and the initial voltage distribution within the channel, all within reasonable limits, waveforms with rise times of between 1 and 10 microseconds and times to one half of peak value of between 10 and 250 microseconds were constructed. These waveforms are then used to compute electrical and magnetic fields to determine indirect as well as direct effects on aircraft.
