The leader precedes in steps of 20–30 m toward the ground, each step forming further ionization of the subsequent step. Simultaneously, from the high points or structures on the ground upward leaders of positive charges start forming. 3). The lightning flash along the ionized path causes a very high peak of current amounting to several kilo amperes and dissipates its energy in the form of heat (temperatures up to 20 000˚C for a few microseconds), sound and electromagnetic waves (light, magnetic fields and radio waves).
