Abstract

The conditions for the formation of ball and cylindrical streamers in a corona discharge were studied. It is shown that formation of cylindrical streamers from a positive tip or from a plasma at a positive tip can explain the stepwise progression of the main negative leader in lightning and during the breakdown of long gaps.
