Elves and Sprites
Upper atmospheric lightning or upper atmospheric discharge are terms sometimes
used by researchers to refer to a family of electrical breakdown phenomena that occur well
above the altitudes of normal lightning. The preferred current usage is transient luminous
events (TLEs) to refer to the various types of electrical discharge phenomena in the upper
atmosphere, because they lack several characteristics of the more familiar lower
atmospheric lightning. TLEs include red sprites, sprite halos, blue jets, gigantic jets,
and elves.
