Whats the difference between a thunderstorm and a supercell?
Supercells are similar to other thunderstorms, except they’re bigger, stronger, and meaner. While a strong thunderstorm, associated with a passing cold front, may produce a tornado, supercells can produce several tornadoes. One of the things that separates supercells from the “ordinary” thunderstorms is that violent updrafts and downdrafts reinforce each other, which allows a supercell to be sustained for an hour or more.
