| Abstract: | Physical arguments about the possible mechanism of formation of a leader channel are presented. A mathematical model describing
steady-state leader breakdown is constructed. An algorithm for determining the propagation velocity, dimensions, and electric
field in the streamer zone is developed. A numerical simulation of the channel formation stage in the plasma of a streamer
zone a nitrogen atmosphere is performed. The dependence of the leader velocity on the potential is obtained. The tentative
model proposed here can be used to describe the leader breakdown of a long gap at high positive potentials.
