Abstract
The pressure jump method was used to determine the energy release in an apokampic discharge at various air pressures. The maximum energy release and electroluminescence in the NUV spectral range are achieved in the pressure range from 85 to 92 Torr, which roughly corresponds to the formation heights of such optical phenomena in the middle atmosphere as blue jets, starters, and giant jets. The facts found make it possible to supplement the picture of the formation of these phenomena.
