During the Preliminary Breakdown are formed conductive paths in the air, which are characterized by higher conductivity and during the journey from cloud to ground may Stepped Leader be conducted through them. For example, from piles of manure are continuously evaporating various vapors strongly dissociated, increasing the conductivity of the air above them by several orders of magnitude, to the heights of tens and even hundreds of meters in no wind.
Wakati awali mapito conductive Breakdown ni sumu katika hewa, ambayo ni sifa kwa conductivity na Higher Wakati wa safari kutoka wingu na ardhi inaweza kuwa kupitiwa Kiongozi umefanywa kupitia Them. Kwa mfano, kutoka marundo ya mbolea ni Kuendelea kuyeyuka mivuke mbalimbali sana dissociated, Kuongeza conductivity ya hewa juu ya mandhari kadhaa kwa amri ya ukubwa, ya urefu wa makumi na hata mamia ya mita katika upepo hakuna.
