During only hundred millionths of a second, what is the time during that is radiated power of the vast part of subsequent lightning stroke - more 99%, is the column of air edge moving "only" sound velocity, to a distance 30 mm. Electromagnetic radiation from the subsequent electric discharge moved at the same time to a distance of 30 km, and that rays, propagating in all directions, may be within such a column about 300 - 30000 (depending on the angle) times bounced and create many sorts of resonance and interference effects.
Umeme kutoka mionzi kutokwa baadae umeme wakiongozwa na wakati huo huo kwa umbali wa kilomita 30, na kwamba rays, kuikuza katika pande zote, inaweza kuwa ndani ya safu vile kuhusu mara 300 bounced na kujenga aina nyingi ya resonance na kuingiliwa.
