Only to a very limited degree. Analysis of weather conditions can help determine the potential for tornadoes, including strong tornadoes, across a region on a given day. However, it cannot predict how strong individual tornadoes will be or where they will strike. We can also tell if a specific storm cell has potential to produce strong tornadoes, but we still cannot predict excactly when a tornado will form.
Just about. Probably the only areas that can't get tornadoes are extreme polar climates such as Antarctica and extreme deserts such as the Atacama.
There is not real scientific evidence that animals predict tornadoes. Tornadoes come with thunderstorms, and some animals, such as dogs, may hear the thunder before we do, but it is unlikely that they can actually predict tornadoes.
It depends on what you mean by extreme. Tornadoes of EF4 and EF5 tornadoes, however are often referred to as violent tornadoes. These account for about 1% of all tornadoes.
No, not really. The national weather service can see that some conditions exist that could lead to a tornado, but they can not predict when it will happen or where.
Temperature, Doppler radar, and wind direction are some of the types of information used to predict tornadoes.
Tornadoes can be predicted only to a very limited degree. By looking at weather conditions meteorologists can sometimes predict if a large general region might get tornadoes hours or even days ahead of time, but not exactly where or when tornadoes will strike. On a time scale of minutes meteorologists can often tell if a thunderstorm has the potential to produce a tornado, but still cannot be certain if a tornado will form or exactly where it will go.
It is impossible to predict what counties will and won't have tornadoes at any given time. Tornadoes are very difficult to predict.
No, it is not
Tornadoes can happen in any place that gets thunderstorms.
Tornadoes happen every year.
To predict is to say what will happen or what you think will happen.
Tornadoes happen in Miami for the same reason they happen anywhere else. See the related question for how tornadoes form in general.
