Tornadoes are fascinating yet disastrous weather
Time for a Twister
When two weather fronts meet the atmosphere becomes unstable. Usually this happens when a warm front meets a cold front. When this happens, a thunderstorm is born. Most thunderstorms are harmless events. However, when a thunderstorm starts to rotate into a supercell a funnel cloud may appear. Touching the ground, a funnel cloud is now called a tornado.
