Neobychnyi uzor sozdayut atmosfernye gravitacionnye volny – volny izmenyayushegosya davleniya vozduha, kotorye mogut rasti s vysotoi v razrezhennom vozduhe, v etom sluchae do vysoty pochti v 90 kilometrov. V otlichie ot polyarnyh siyanii, energiyu kotorym dayut stolknoveniya zaryazhennyh chastic s vysokoi energiei na bol'shih vysotah, atmosfernoe svechenie ob'yasnyaetsya hemilyuminescenciei – izlucheniem sveta pri himicheskih reakciyah. Obychno atmosfernoe svechenie vidno okolo gorizonta, blagodarya emu nochnoe nebo nikogda ne byvaet polnost'yu temnym.
