Study Notes
Formation of Tornadoes
- Warm air rising causes rotation, forming a funnel.
- Faster spinning air creates a low-pressure area, drawing in more air and objects.
- Supercells (severe thunderstorms) can last for hours, unlike ordinary thunderstorms lasting 30-60 minutes.
Tornado Frequency and Location
- The US experiences around 1,200 tornadoes annually.
- "Tornado Alley" has unique geography, increasing tornado risk.
- Dry air from the Rockies, warm, humid air from the Gulf of Mexico, and cold air from the Arctic collide, creating ideal storm conditions.
