Abstract
The propagation velocity of plasma plumes in the presence of an external electric field was measured in air, at a pressure corresponding to the altitudes of the middle atmosphere transient luminous events. Based on the results, a hypothesis is formulated that the transient type starting from the thundercloud dome (blue jet, starter, gigantic jet) depends on the intensity of intracloud lightings and the ratio of the positive charge of the dome top and the negative charge of the outer layer.
