Narrator: Each year, America gets around four times as many twisters as the rest of the world COMBINED. Taken altogether, countries outside the US see around 200-300 twisters annually. Compared to more than 1,200 that strike American soil. So, what makes the US so special?
To make a tornado, you need just the right mix of ingredients: Warm, humid air near the ground. Cold air higher up in the atmosphere. And wind that overlaps while moving at different speeds or directions. Believe it or not, few places on Earth check all of these boxes. And none compares to the Great Plains of the United States — AKA, tornado alley.
