On presentation of lightning flash in thundercloud as collective spontaneous radiation (superradiation) pulse

In this paper we conjecture that some specific properties of an electroactive region of thunderclouds play the major role in an initiation of a lightning flash. The electroactive region is modeled here as a quantum two-level system of oxygen molecules which are assumed to have two (ground and excited) states, where transitions from ground to excited states come as a result of micro-discharges between ice particles. In this case lightning flash corresponds to the pulse of collective spontaneous radiation caused by the deexcitations of excited oxygen molecules from metastable state into ground state.

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.
