Firefighter captures pic of terrifying ‘fire whirl’
(CNN) -- Some say the world will end in fire, but even those who favor such a Frost-ian demise probably don't want to be done in by something as abjectly terrifying as this "fire tornado." Fire tornadoes, or fire whirls, are real things. But despite the name, they aren't some sort of horrible conflagration of fire and an actual tornado. Fire whirls happen when hot, dry air close the the ground -- like that near a fire -- rises rapidly in a column, forming a vortex.
