Rotational dynamics of a ball lightning

Abstract

In this paper we study rotational dynamics of a ball lightning. Cases of deceleration and acceleration of rotation are described, which suggests that the cause of rotation may be the internal movement of elements of the ball lightning core. A model for particles separation from the surface of a rotating ball lightning is presented. It is also shown a qualitative explanation of the interaction of rotational moments of the ball lightning core elements, causing a change in the rotation speed of the ball.
