The 3 general categories of tornadoes are weak tornadoes (EF0 and EF1), strong tornadoes (EF2 and EF3), and violent tornadoes (EF4 and EF5). These categories are based on the Enhanced Fujita (EF) scale, which rates tornado intensity based on the damage they cause.
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.
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.
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..
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.
On The Fujita scale and the later Enhanced Fujita scale there are 6 categories: F0 to F5 and EF0 to EF5 respectively. The TORRO scale, used by some European countries, has 12 categories from T0 to T11, with every two categories equivalent to one category on the Fujita scale.
Cyclones are typically categorized into five main categories based on their wind speed: tropical depression, tropical storm, category 1, category 2, category 3, category 4, and category 5. Each category is defined by a specific range of sustained wind speeds.
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.
"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.
Tornadoes do not have names. Australia has had many tornadoes, too many to list here.
The most common intensity levels are EF0 and EF1, which are also the two weakest categories.
There were 934 tornadoes in the U.S. in 2002. Worldwide it is harder to determine as many countries do not keep records of tornadoes
