NATURAL PHENOMENON

Fire Tornado A fire tornado, also known as fire whirl, fire twister, or firenado is a whirlwind which is made up of ash or flame. Fire tornadoes begin with a swirl of smoke or wind. They usually occur when the turbulent wind conditions combine with the increasing heat from the fire to create a rotating eddy of air. The eddy then expands into a tornado-like vortex which sucks in combustible gases and burning debris. Even though a fire whirl is informally known as a firenado, it is not frequently classified as a tornado since its vortex does not always stretch from the base of the cloud to the ground. Fire whirls are not classic tornadoes since their vorticity derives from the temperature-induced lifting and surface winds instead of the tornadic mesocyclone aloft. A mesocyclone is an air vortex which is created in a convective storm. The rising air revolves around a vertical axis in a similar direction as the low-pressure systems in the specified hemisphere.
