At the phase interface of the shock waves propagating through the air and other elements contained in it. Dust, humidity, highly ionized particles, there happens to enormous friction, formation of secondary electric charges, and most likely has a very high electrical conductivity.
Katika interface awamu ya mawimbi mshtuko kuikuza kwa njia ya hewa na mambo mengine yaliyomo ndani yake. Vumbi, unyevu, chembe sana ionized, kuna hutokea na msuguano mkubwa sana, malezi ya mashtaka ya sekondari ya umeme, na uwezekano mkubwa zaidi ina juu sana umeme conductivity.
