On Possibility of Electromagnetic Nature of Atmospheric Intensive   Vortices Generation
  Our goal is to find out possible appearance of rotational motion in the atmosphere, created by a lightning. A positive solution of this question, in the end, leads to a necessity of accepting that processes of birth and annihilation of electron-positron pairs take place in the leader head of lightning channel. Under this condition, within the framework of our physical model of development of a lightning, we suggest a logical explanation of the stepwise structure of a negative leader, intensive radio emission produced by lightnings, gamma-ray flashes from thunderstorm and anomalously intensive electric currents from positive leaders. As for the development of intensive tornado it is determined by pumping of the angular moment produced by lightnings in a local area of the thunderstorm.
