Why do Tornados only happen in the US?

Answer 1

That is no true. Tornadoes occur almost all over the world and have touched down on every continent except Antarctica.

The U.S. however, gets more tornadoes and stronger tornadoes than any other country. This is due to the fact that the country has a very large land area and has a large region where 80% of its tornadoes occur called Tornado Alley.

Tornado Alley experiences the perfect combination of colliding air masses, wind shear, and a strong "cap" of stable air for the formation of tornadic supercells. Other tornado producing regions in the world, such as in Argentina, do not have quite the same setup.

Answer 2

Tornados can happen in various parts of the world, but the United States experiences a higher frequency due to a combination of geography and weather patterns. The central part of the country has the perfect conditions for tornado formation, such as warm moist air from the Gulf of Mexico colliding with cool dry air from the north. This makes the US more prone to tornadoes compared to other regions.
