摘要

Ball lightning is pictured as a negatively charged spherical bubble with a shell of oriented dipolar water molecules. The bubble is balanced by outward electrostatic stress and inward forces of atmospheric pressure and/or surface tension forces. Because of the low electronic conductivity of condensed water, electrons slowly leak away from the surface in the radial direction, forming a corona. The charge on the ball decays exponentially with a characteristic mean life time depending on the electronicconductivity of the shell. Protons confined in the shell induce an electric conductivity to the shell in the tangential direction. When the bubble is deformed by an inductive field, mobility of the protons develops a higher charge density in the more curved regions of the shell. Differential electrostatic stress generates a feedback propelling force enabling it to bounce off from surfaces or penetrate through holes.
