Approximately 75% to 90% of all recorded tornadoes in the world occur within the United States, making it the most tornado-prone nation globally. This extraordinary frequency is driven by the unique geographical collision of warm, moist tropical air streaming northward from the Gulf of Mexico meeting cold, dry polar air pushing down from Canada across the flat terrain of the central plains, creating optimal atmospheric instability for severe supercell thunderstorms and frequent tornado outbreaks.
