Физическое моделирование шаровой молнии

Abstract

Lightning ball (LB) is one of the faintly studied natural phenomenon. All information about LB wasobtained from eyewitnesses questioning. Nowadays there are experiences of creating LB, but nobody can createplasmoid, which would have lifetime more than one second. In this paper the LB creation experiment reveals thatplasmoid better fit the LB description if solution contains certain amount of salt is presented. From obtainedcurrent waveforms and high speed camera images one can make a conclusion that when the current starts fallingdown from its maximum value the transition from gliding discharge to plasmoid forming begins. Ball shapedplasmoid have not been fixed. In the future investigations changing the solution salt composition and fixation of plasmoid spectrum are planned.
