What is "Tornado Alley"?
A section of the Great Plains in the central part of the United States is called "Tornado Alley". This is because more tornadoes form here than any other part of the country. The plains are flat which allows cold polar air from Canada to meet warm tropical air from the Gulf of Mexico. Storm chasers go Tornado Alley looking for tornadoes because there are so many that form there.
