After an area catches fire, the air above the area becomes extremely hot and rises rapidly. Cold air then rushes in at ground level from the outside to replace the rising air, creating high winds which fan the flames at ground level further. This creates a self-sustaining firestorm with temperatures peaking at over 2,000 degrees Celsius fed by the influx of oxygen. Experiments with test fires have shown that firestorms can create fast-moving vortices of fire, which can spread the fire beyond the area of the original fire. The winds in some of these fire vortices can reach tornadic strengths, effectively creating a fire tornado. These fiery tornadoes can complicate the jobs of firefighters in combating the inferno. firetornado	*
