Tornadoes are one of the most feared weather events on Earth. These quick-forming and normally short-lived cyclones tend to emerge from strongly rotating thunderstorms known as supercells. Driven by a long-lasting tower of rising air, these storms can unleash some of the fastest surface winds on Earth. Rising as much as 16.1 kilometers (10 miles) high, supercells can encompass a volume of air up to 25 times the size of Mount Everest. Some have been known to pummel the ground with hailstones the size of grapefruits.
A Supercell Thunderstorm Cloud Over Montana
Is that a spaceship or a cloud? Although it may seem like an alien mothership, it's actually a impressive thunderstorm cloud called a supercell. Such colossal storm systems center on mesocyclones -- rotating updrafts that can span several kilometers and deliver torrential rain and high winds including tornadoes. Jagged sculptured clouds adorn the supercell's edge, while wind swept dust and rain dominate the center. A tree waits patiently in the foreground. The above supercell cloud was photographed in 2010 July west of Glasgow, Montana, USA, caused minor damage, and lasted several hours before moving on.
