Tornadoes are sometimes divided into "weak" tornadoes "strong" and "violent" tornadoes.
Weak tornadoes are those rated EF0 and EF1. Most tornadoes are weak.
Strong tornadoes are those rated EF2 and EF3.
Violent tornadoes are those rated EF4 and EF5. They are the rarest of tornadoes, only about 1% of tornadoes are this strong.
the types of tornadoes are: super cell tornadoes, landspouts, and waterspouts.There are two main types of tornadoes: supercell tornadoes and landspouts. There ware waterspouts too, but these are essentially the same as the other two, only on water.
The United States averages about 1200 tornadoes per year, which would work out to about 3600 tornadoes in an average 3-year period.
No, gustnadoes are not tornadoes. Gustnadoes are short-lived, spinning wind events that form along the gust front of a thunderstorm. They are not connected to the cloud base like tornadoes and generally have weaker wind speeds.
There definitely are F5 tornadoes. The Fujita scale does have categories up to F12 but these are pretty must just theoretical. Since the scale rates tornadoes on damage an F5 damage is total destruction, it is unlikely that any tornado will ever be rated higher than F5. On the Enhanced Fujita scale the highest category is EF5 no question about it.
There were 1,098 confirmed tornadoes in the United States in 2007.
There are six categories from EF0 to EF5.
The Tornadoes website offers a variety of information about tornadoes. These include: types and categories of tornadoes, weather conditions that signify tornadoes forming, and safety tips.
general categories
There are no categories for waterspouts specifically. However, waterspouts that hit land are counted as tornadoes. Tornadoes are rated on the Enhanced Fujita scale, which has six levels from EF0 to EF5. Very few waterspouts are stronger than EF1.

On average, Nebraska experiences around 57 tornadoes each year. The tornadoes range from weaker EF0 and EF1 categories to stronger EF2 and EF3 categories. Nebraska typically sees the highest tornado activity in the spring and early summer months.
Tornadoes happen in Miami for the same reason they happen anywhere else. See the related question for how tornadoes form in general.
There are 2 most general categories. These are metals and non-metals.

"Water tornadoes," which are called waterspouts, are divided into two categories. Fair-weather waterspouts, are structured differently and generally weaker than classic tornadoes. Tornadic waterspouts are ordinary tornadoes that happen to be on water, they are just as strong as ordinary tornadoes.
Yes. The Enhanced Fujita scale has six intensity categories ranging from EF0 for the weakest tornadoes to EF5 for the strongest. This identifies different levels of strength rather than actual types of tornado. As far as actual types, there are classic supercell tornadoes, which form from a larger mesocyclone, and weaker landspouts, which form as a result of processes beneath a thunderstorm.
If general weather conditions favor the formation of tornadoes then a tornado watch is issued.
