Pictures: Fire "Tornado" Spotted—How Do They Form?


A fire tornado blazes near Curtin Springs, Australia, in a still of a recently released video.

Chris Tangey of Alice Springs Film and Television was filming a wildfire when a small twister touched down, "causing it to build into a spinning flame," according to Australia's WPTV.com. (Watch a video of the fire tornado.)

Also known as fire whirls, fire devils, or even firenados, these whirlwinds of flame are not really rare, just rarely documented, Jason Forthofer, a mechanical engineer at the U.S. Forest Services's Missoula Fire Sciences Laboratory in Montana, said in 2010.

As Tangey told Northern Territory News, "It sounded like a jet fighter going by, yet there wasn't a breath of wind where we were."
