Abstract: | Ball lightning is modeled by the bulk of humid air heated to temperatures of 600–650 K and containing a multitude of charged
drops and microbubbles of size 10?5 cm or less, as well as water vapor heated to a near-critical temperature. The condensation of the vapor in the microbubbles,
followed by the cooling of resulting droplets, generates energy spent on the thermal radiation of ball lightning. The radiation
of light and radio waves is explained by the motion of ions and electrons in the electric field of charged bubbles and droplets
and by the thermal rotational motion of charged droplets. As a result of coagulation, the droplets overheat and tend to collapse.
An external electric field, supersaturated water vapor condensation, and a number of other factors may contribute to the ball
lightning explosion energy. |
