Why do tornadoes form from thunderstorms instead of ordinary rain clouds?
WeatherSevere Storms
Quick Answer
Tornadoes need severe thunderstorms with strong wind shear and powerful updrafts that can spin air vertically. Ordinary rain clouds usually do not have enough energy or rotation.
The Full Story
The most tornado-producing storms are supercells, which contain a rotating updraft called a mesocyclone. Wind shear, meaning winds changing speed or direction with height, helps create that rotation. When the storm stretches the rotating air upward, the spin tightens and can form a funnel cloud and then a tornado if it reaches the ground. The United States sees the highest number of tornadoes because its geography often sets up the needed air-mass collisions.
