The generalized traveling current source return
stroke model (GTCS), Cvetic and Stanic [1995] is extended to
take into account current reflections occurring at ground and at
the upper end of the lightning channel, as well as current
attenuation along the channel. The ground reflection factor and
the top reflection factor of the current pulses are taken from the
extended TCS model, Heidler [2007]. Current sources are placed
along the activated length of the lightning channel, represented
by the channel discharge function introduced in the GTCS
model. Multiple reflections give rise to current waves moving up
and down along the lightning channel. The total current is
composed of the source current according to the original GTCS
model and the reflected currents. The current along the channel
can be represented as a sum of integrals of current sources along
the channel. The traveling-current-source-type of “engineering”
return stroke models can be regarded as special cases ...of the
extended GTCS model. Moreover, for a convenient set of input
parameters, the transmission-line-type of return stroke models
can be also derived from the extended GTCS model.
Simultaneously, the existence of the current source at the channel
base, inherently built in all transmission-line-type of models is
explained. This result is purely theoretical, since these two classes
of “engineering” models are based on different physical pictures
that describe processes in the lightning channel during the return stroke.
