There are a number of reasons Tornado Alley gets so many tornadoes. The region is the site of frequent collisions of warm, moist air from the Gulf of Mexico, cool air from Canada, and dry air from the Rockies. These collisions result in very strong thunderstorms, with the moist air acting as their "fuel." Additionally, the region often has a layer of stable air called a cap that suppresses storms, allowing only the strongest to develop. As a result the strong storms don't have to compete with weaker ones for energy and so become even stronger. Finally, the region often sees strong vertical wind shear, or a variation of wind speed and direction with altitude. This tilts them in such a way that the updraft and downdraft portions becomes separated and don't interfere with one another, letting the already strong storm further strengthen and last longer. The wind shear also sets the storms rotating, turning them into supercells, the most powerful thunderstorms on earth. It is the rotation within these supercells that can develop into a tornado.

Other parts of the world do see such conditions and thunderstorms at least occasionally, but not with the same frequency as in Tornado Alley.

Most tornadoes located?

Most tornadoes in the world are located in the central part of the United States, often referred to as "Tornado Alley." This region spans from Texas to South Dakota and is known for its frequent tornado outbreaks due to the collision of warm, moist air from the Gulf of Mexico with cooler, drier air from the Rocky Mountains. Tornadoes can occur in other parts of the world as well, but Tornado Alley experiences the highest concentration of them.
