Have You Spotted Any Of These Striking Cloud Formations?

Polar stratospheric clouds are some of the highest on Earth, and, true to their name, they form close to the poles. The humongous anvil clouds may look awesome, but they have the potential to be dangerous-they can contribute to supercells, thunderstorms known to produce tornadoes and hail stones the size of tennis balls.
