Poyasnenie: Chto eto za oblako? Eto - grozovoi vorotnik (meteorologicheskii termin, roll cloud). Takie redko vstrechayushiesya dlinnye oblaka mogut formirovat'sya okolo nastupayushego holodnogo fronta. Esli nishodyashii potok vozduha ot nadvigayusheisya buri zastavlyaet teplyi vlazhnyi vozduh podnimat'sya, to on ostyvaet nizhe tochki rosy, i togda obrazuetsya oblako. Kogda eto proishodit odinakovym obrazom vdol' protyazhennogo fronta, mozhet obrazovat'sya grozovoi vorotnik. V takom oblake vozduh mozhet vrashat'sya vokrug ego dlinnoi gorizontal'noi osi. Schitaetsya, chto grozovoi vorotnik ne mozhet prevratit'sya v tornado. V otlichie ot pohozhih vystupayushih oblakov (shelf clouds), grozovoi vorotnik polnost'yu otdelen ot porodivshih ego kuchevo-dozhdevyh oblakov. Na etoi fotografii my vidim, kak daleko vytyanulsya grozovoi vorotnik letom 2005 goda nad Olbani v shtate Missuri, SShA.
