The central plains of the United States form a region called Tornado Alley, which has an ideal climate setup for tornadoes. In the spring storm systems cause warm, moist air from the Gulf of Mexico to collide with cool air from Canada and dry air from the Rockies, resulting in the formation of strong thunderstorms. About a mile off the ground a layer of stable air holds thunderstorm activity back, allowing instability to build underneath it. As a result when the storm break through the cap the instability will be enormous, leading to explosively powerful thunderstorms. At the same time wind speed and direction varies with altitude, which sets these storms rotating and also strengthens the updraft. This rotation combined with strong thunderstorm updrafts can then produce tornadoes.
Similar conditions can occur elsewhere, but not nearly as often.

What continents countries and cities are affected by the tornadoes?
Tornadoes can occur on every continent except Antarctica, but they are most common in North America. Countries like the United States, Canada, Australia, and parts of Europe can experience tornadoes. Cities in Tornado Alley, such as Oklahoma City, Dallas, and Kansas City, are most susceptible to tornadoes in the United States.
Why are people most affected by tornadoes?
Because they are not very heavy, therefore being easily lifted off the ground and thrown about. Although, to be fair, they aren't the MOST affected, as all smaller animals than humans can be more easily lifted and thus are more affected than people are. The exception to this being birds, because they fly and are usually able to avoid the path of a tornado. Large animals on the other hand, like cows or giraffes, are not as affected because their weight provides more resistance to the tornadoes.
