Abstract
The sequence of appearance of various atmospheric discharges (lightning, elve, and blue jet) shown on video from the International Space Station is analyzed. For comparison, experimental data on the formation of diffuse, corona, and apokampic discharges with participation of cylindrical and spherical streamers are used. It is assumed that the formation of the elve filmed from the space is initiated by extensive discharges in clouds with subsequent formation of lightning closed to the Earth in this area. In this case, the lightning reaches the positively charged upper cloud layer. The dense plasma of the upper part of the lightning initiates the development of a blue jet, consisting of cylindrical streamers of the ionization wave.
