2005) documented that current and light signals at the bottom of the rocket-triggered lightning channel exhibit a linear relationship along the rising portions of their waveforms (i.
In addition, the speed of advancement of the oncoming ascending leader depends on the potential of the head of the lightning channel, which also has a random value.
Objective: More than 250 years after establishing the electrical nature of the lightning flash, we still do not understand how a lightning channel advances.
The negative leader grows toward the ground with a quite good directivity, while the positive leader is divided into three main branches and each of them may develop into the lightning channel potentially.

The aircraft-lightning electrodynamics must take into account the following two facts: (a) the aircraft is an electric conductor carrying the lightning stroke wave [4-7], and (b) the lightning channel is an electric plasma phenomenon [8-12].
But recent work by Cummer and other researchers suggests that TGFs are born in the first milliseconds of a lightning flash, when there is but a single lightning channel moving almost directly upward.
The diameter of the larger fasteners is not much different than that of the actual lightning channel.
Electromagnetic effect damage is caused by currents induced by the electromagnetic pulse emanating from the lightning channel or from the object which is struck.
