Yes, generally, they are, though that does not mean that Canada does not get violent tornadoes.
Tornadoes are most commonly found in the central United States, often referred to as "Tornado Alley," which includes states such as Texas, Oklahoma, Kansas, and Nebraska. They can also occur in other regions around the world, but with lower frequency.
Yes. Florida is about tied with Oklahoma for third place in highest annual number of tornadoes, behind Texas and Kansas. However, the tornadoes in Florida are generally much weaker than those on the Greak Plains, with very few rating higher than EF2.
Hurricanes are tropical weather systems while significant tornadoes generally occur in the temperate latitudes. The wind currents that move storms in the tropics are generally weaker than those that move storms in the temperate latitudes.
When thunderstorms occur with strong, intense winds. tornadoes form when those winds start to rotate tornadoes form
It is estimated that 3 out of every 4 tornadoes occur in the United States, 80% of those occur on the Great Plains, also known as Tornado Alley.
Tornadoes are more common in areas with warmer climates than those with cold ones.
Surprisingly, Florida actually has the highest occurrence of tornadoes per square mile. However, these tornadoes are generally weaker than those in Tornado Alley.
Violent tornadoes (those rated F4 and F5) most often strike in late spring or early summer. However, they can occur at any time of year.
All tornadoes are dangerous. However, the tornadoes in Florida tend to be weaker than those in other regions such as Tornado Alley Because of this they pose somewhat less of a risk.
Tornadoes do occur in California, but they are rare and those that do occur usually weak, rarely exceeding F1 intensity. One major reason tornadoes are not a major threat is that there are cold ocean currents off the California coast, which stabilize the atmosphere, making it hard for the strong thunderstorms that produce tornadoes to form.
It is difficult to say how many there were exactly. Officially there were 945 recorded, but the real number is likely much higher. At that time we missed a large portion of the weaker tornadoes, those that would be rated F0 or F1, and the majority of tornadoes fall into these categories..
Worldwide statistics are not available as most countries do not keep records and some of those that do do not have them easily accessible. The U.S. where the greatest portion of tornadoes occur experienced 1075 tornadoes in 2000.
