Generation of confined plasma balls propagating along discharge channels: A comparison with ball lightning

Blog Article

Ball lightning is a mysterious phenomenon reported by numerous eyewitnesses.The very limited instrumental characterization of ball lightning recorded in nature has maintained the mystery surrounding this phenomenon and given rise to many theories on their generation mechanism.In this work, we reproduced conditions in the laboratory similar to thunderstorms and Anti-Aging observed the generation of luminous plasma balls.The formation of these plasma balls is based on the confinement of the ejected plasma from the ground into the lower pressure channel produced along the path of the discharge.The spectral, temporal, and spatial characterizations done in this work can give some indications on the formation of ball lightning and more particularly its containment with quasiconstant diameter, its average speed, its erratic path, and the various Crates colors of ball lightning observed in nature.
