Tornadoes need strong thunderstorms in order to form. Thunderstorms, especially strong ones require warm moist air to power them. Cold air simply does not have enough energy.
Tornadoes can occur in most climates, but are more common in areas with hot climates. However, temperature is not the only factors. Tornadoes are rare in arid regions, for example.
Tornadoes are more common in areas with warmer climates than those with cold ones.
Tornadoes can occur in just about any climate except for polar climates and extremely arid climates. They are most common in temperate and subtropical climates.
:( every state has a tornado. Alaska has even had a tornado
Tornadoes are most common in temperate climates, particularly those that will produce grasslands.
Tornadoes can occur in Vancouver. One struck in 2008. However, they are rare in that area because the cold water nearby stabilizes the atmosphere.
No. It is too cold in Antarctica for tornadoes.
Tornadoes are most common in temperate or subtropical climates.
Tornadoes can merge, though it is a rare event.
Tornadoes are very rare in Alaska and Hawaii, not common. Alaska's cold climate makes it difficult for strong thunderstorms to form. Since Hawaii is tropical it is not prone to the frontal systems that produce most tornadoes.
There are tornadoes in California, but they are rare and usually weak. The main reason is that cold ocean currents of the California coast tend to stabilize the atmosphere, making it difficult for the strong thunderstorms that produce tornadoes to form as such storms need an unstable atmosphere.
Tornadoes are likely possible in Rio, but rare.
