Why there are tornados?

Question

Why there are tornados?

Answer 1

The United States has the most tornadoes of any country, about four times more than estimated in all of Europe, not including waterspouts.[47] This is mostly due to the unique geography of the continent. North America is a relatively large continent that extends from the tropical south into arctic areas, and has no major east-west mountain range to block air flow between these two areas. In the middle latitudes, where most tornadoes of the world occur, the Rocky Mountains block moisture and atmospheric flow, allowing drier air at mid-levels of the troposphere, and causing cyclogenesis downstream to the east of the mountains. The desert Southwest also feeds drier air and the dry line, while the Gulf of Mexico fuels abundant low-level moisture. This unique topography allows for many collisions of warm and cold air, the conditions that breed strong, long-lived storms many times a year. A large portion of these tornadoes form in an area of the central United States known as Tornado Alley.[4] This area extends into Canada, particularly Ontario and the Prairie Provinces. Strong tornadoes also occasionally occur in northern Mexico.

Answer 2

Tornadoes occur because of the favorable conditions for them. The United States has more tornadoes than any other country in the world. One prominent role in the development of tornadoes in wind shear, which is the change in wind speed and direction with height.
