Each number corresponds to a level of damage and intensity. The higher the number, the more severe the damage.
F0 (light damage): Shingles peeled from roofs, tree limbs broken, weak rooted trees toppled.
F1 (moderate damage): Roofs of homes severely damaged. Trailers overturned.
F2 (considerable damage): Roofs torn from frame houses. Trailers completely destroyed.
F3 (severe damage): Walls collapse in well built houses. Most trees in a forest are uprooted.
F4 (devastating damage): Well built houses leveled. Trees debarked.
F5 (incredible damage): Strong frame homes leveled off foundations and swept away.

What are the names of the scales used to measure the intensity of a tornado?
The intensity of tornadoes is measured on the Fujita-Pearson Tornado Intensity Scale, or "F-Scale". This scale was named after the men who developed it, Dr. Theodore Fujita, and Allan Pearson, head of the Forecast Center in Kansas City. It ranges from F0 for the weakest tornado to F5 for the strongest. In 2007 the National Weather Service in the U.S. upgraded to the Enhanced Fujita Scale, with the intention of providing more detailed and accurate ratings, which includes adjusted wind speed estimates. Overall, though, the damage done by each intensity category remains largely the same. Similar to the original scale, it ranges from EF0 to EF5. The U.K. utilizes the TORRO scale, which uses similar damage and wind ranges to the Fujita-Pearson scale, but has two levels for every one on the F-scale, ranging from T0 to T11.
What scale do they us for tornadoes?
There are three scales used for rating tornadoes. All of them use damage to estimate wind speed. The best known scale and first to be developed is the Fujita (F) scale,created in 1971, which goes for F0 at the weakest to F5 at the strongest most countries today use the Fujita scale. Next is the little-known TORRO (T) scale developed in 1975. It goes from T0 at the weakest to T11 at the strongest. In a sense it divides each level on the Fujita scale in two (T0 and T1 equal an F0, T10 and T11 equal an F5). It is used chiefly in Britain. Finally there is the Enhanced Fujita (EF) scale, developed in 2007, which goes from EF0 to EF5. It is much like the original Fujita scale and has much the same categories. But it involves more detailed damage analysis and uses different wind estimates as the original one were found to be inaccurate, especially for F4 and F5 tornadoes. It is used only in the U.S.
What are the similarities of the F-scale and saffir Simpson scale?
Both scales measure the intensity of rotating storms (the F or Fujita scale rates tornadoes while the Saffir-Simpson scale is used for hurricanes). Both scales have corresponding wind ranges for each category, and the strongest category on each scale is a rating of 5. However, there are some differences. The Saffir-Simpson scale uses direct wind speed estimates while the Fujita scale rates tornadoes based on damage. Also, while the Saffir-simpson scales has 5 levels, category 1 though category 5, the Fujita scale has 6, F0 through F5. F0 wind estimates correspond roughly to those of a tropical storm. Also, the wind ranges of most categories differ significantly, especially in higher categories.
Why do the saffir-Simpson scale and fujita scale differ?
First and foremost, the Saffir-Simpson scale is used to rate hurricanes while the Fujita scale is used to rate tornadoes. The Saffir-Simpson scale is based on direct wind measurements, with the winds for each category generally being lower than those of the "equivalent" levels on the Fujita Scale (now the Enhanced Fujita scale in the U.S.), for example, a category 5 Hurricane starts at 156 mph while an F5 tornado starts at 261 mph (201 mph for an EF5). Furthermore, the (Enhanced) Fujita scale bases ratings on damage rather than direct wind measurements, with the winds being estimates. These differences are dues to the fact that tornadoes are much smaller and shorter-lived than hurricanes, making it very difficult or even impossible to get direct wind measurements. The winds for the (E)F scale categories are higher than those on the Saffir-Simpson scale largely because tornadoes can have much faster winds: tornadoes can have winds over 300 mph, while the very strongest of hurricanes have winds of about 200 mph.
Why is severity of tornadoes use fujita scale?
Scientists use the degree of damage inflicted on man-made structures and vegetation to rate tornadoes. Quality of construction is taken into account. Here are the levels on the scale with typical damage associate with them F0 (light damage): Tree limbs broken, shallow rooted trees toppled, some roof tiles peeled off F1 (moderate damage): Significant loss of roof surface, mobile homes overturned or badly damage, windows broken, garages and porches may collapse. F2 (significant damage): Roofs torn from well built houses, trailers completely destroyed, large trees snapped. F3 (severe damage): roofs and walls torn from well built houses, most trees in a forest uprooted, large vehicles lifted off ground. F4 (devastating damage): Well built houses leveled, poorly built houses blown some distance, trees debarked F5 (incredible damage): Well built houses wiped clean off foundations, cars and larger objects tossed great distances, concrete structure heavily damaged.
What does a diagram of the Fujita scale of a tornado look like with a picture?
Wikipedia's article on the Fujita scale provides a good table with pictures of the damage at each level.
What are the rating systems for tornadoes?
There are three scales that are used. The Fujita scale is perhaps the most popular. It rates tornadoes from F0 to F5 based on damage and provides wind speed estimates for each category. The TORRO scale, used in some European countries, is similar to the Fujita scale, but rates tornadoes from T0 to T11, having two categories for every one on the Fujita scale. The Enhanced Fujita scale replaced the Fujita scale in the United States. It rates tornadoes from EF0 to EF5, also based on damage. This scale is mostly the same as the Fujita scale only damage analysis is more detailed and the wind estimates for each category have been adjusted, though the damage levels remain the same.
What do the Fujita scale numbers mean?
Each number on the Fujita scale corresponds to an intensity level that a tornado can reach. The lowest value, F0, indicates a weak tornado that breaks tree limbs and peels shingles. The highest value, F5, means an extremely violent tornado that tears well built houses from their foundations.
What does e or f mean in a tornado?
There are three commonly used scales for rating the intensity of tornadoes; the Fujita (F) scale, the TORRO (T) scale, and the Enhanced Fujita (EF) scale. The Fujita or F scale, created in 1971, was the first scale of rating tornadoes to be developed and is the most well known. It uses the severity of damage caused by a tornado to assign it a rating, ranging from F0 at the weakest with relatively minor damage, to F5 at the strongest, with utter devastation. The Enhanced Fujita or EF scale replaced the original Fujita scale in the United States in 2007. It similar to the original scale, running from EF0 to EF5, but has more accurate wind speed estimates for each level and uses more detailed damage analysis. As of 2015 this scale is only used in the United States and Canada.

What are the similarities of the F-scale and saffir Simpson scale?
Both scales measure the intensity of rotating storms (the F or Fujita scale rates tornadoes while the Saffir-Simpson scale is used for hurricanes). Both scales have corresponding wind ranges for each category, and the strongest category on each scale is a rating of 5. However, there are some differences. The Saffir-Simpson scale uses direct wind speed estimates while the Fujita scale rates tornadoes based on damage. Also, while the Saffir-simpson scales has 5 levels, category 1 though category 5, the Fujita scale has 6, F0 through F5. F0 wind estimates correspond roughly to those of a tropical storm. Also, the wind ranges of most categories differ significantly, especially in higher categories.
Is it possible to measure the strength of a tornado?
Yes. In fact the Fujita Scale (replaces by the Enhance Fujita scale in the U.S. in 2007) does just that. It determines the intensity of a tornado based on the severity of damage it causes, ranging from F0 (missing roof tiles, broken tree limbs, etc.) to F5 (houses swept clean off foundations, concrete structures heavily damaged). The Enhanced Fujita scale is very similar, except that damage analysis is more detailed and wind estimates for each level have been adjusted.
Are the rates of tornadoes F1 F2 F3 F4 and F5?
Yes, the rates of tornadoes are categorized according to the Enhanced Fujita (EF) scale, which ranges from EF0 to EF5. EF0 is the weakest category, while EF5 is the most intense and destructive. The rates of tornadoes occurring in each category can vary from year to year.
Why do the saffir-Simpson scale and fujita scale differ?

List the categories of tornadoes and the wind speeds for each one?
Original Fujita scale developed in 1951. Recategorized in 2007, as follows: Enhanced Fujita Scale: EF-065-85mph EF-1 86-110mph EF-2 111-135mph EF-3 136-165mph EF-4 166-200 EF-5 >200 mph
