One term for the event he recorded, a fire tornado, is a misnomer, according to Mark Wysocki, New York's state climatologist and a professor of atmospheric sciences at Cornell University. The columns of spinning fire are much more similar to dust devils than tornadoes, Wysocki said.
Like the dust devils that spring up on clear, sunny days in the deserts of the Southwest, a fire devil is birthed when a disproportionately hot patch of ground sends up a plume of heated air. But while dust devils find their heat source in the sun, fire devils arise from hot spots in preexisting wildfires."
