Огненный смерч
A fire whirl, colloquially fire devil or fire tornado, is a phenomenon-rarely captured on camera-in which a fire, under certain conditions (depending on air temperature and currents), acquires a vertical vorticity and forms a whirl, or a tornado-like vertically oriented rotating column of air. Fire whirls may be whirlwinds separated from the flames, either within the burn area or outside it, or a vortex of flame, itself.
