F3 means roofs and walls torn off houses, up rooted trees and strong winds estimated at 157 to 207 mph (this was later revised to 136 to 165 mph on the Enhanced Fujita scale).
Bases on the damage descriptions of the Fujita scale as severe tornado is one that is rated F3.
It you want to get very technical, they occur in the U.S. and Canada, as these are the only two countries that use the Enhanced Fujita scale. However, if you consider tornadoes of equivalent intensity (F3 on the Fujita scale, T6 and T7 on the TORRO scale), they can occur in most areas that have a temperate to tropical climate that is not arid. In the U.S. all but six of the states have had at least one F3 or EF3 tornado since 1950. Many countries have tornadoes that go unrated that are almost certainly of EF3 intensity, if not higher. The majority of EF3 and stronger tornadoes occur in the U.S.
The Dimmitt, Texas tornado of April 14, 2017 was rated EF3 on the Enhanced Fujita scale, equivalent to an F3 on the Fujita scale. The tornado itself was estimated to be a little bit over a mile wide.
Yes. F0, F1, F2, F3, F4, and F5. The ratings on what is called the Fujita scale are based on damage.
The Fuijta Scale rates tornado from F0 to F5 based on the severity of the damage they cause. An F3 is a strong tornado that will cause severe and often irreparable damage to frame houses. A house that takes F3 damage will lose it roof and many, if not most of the walls will collapse. F3 tornadoes can obliterate trailers (though this is considered F2 damage), throw cars, and lift train cars. About 4% of tornadoes are rated F3.
F3 is a category on the Fujita scale which rates tornadoes From F0 to F5 based on the severity of the damage they do. An F3 is a strong tornado which can tear the roof and walls off most houses, uproot and even throw most trees, and throw trains.
On the original Fujita scale a 200 mph wind would correspond to a strong F3 tornado. However, the wind estimates of the original scale have been found to be too high (actual ratings are based on damage severity). Now, on the more accurate Enhanced Fujita Scale 200 mph would be a borderline EF4-EF5 tornado.
The Fujita scale, or Fujita-Pearson scale, is a scale for rating tornado intensity, based on the damage tornadoes inflict on human-built structures and vegetation. It has six intensity levels ranging from F0 at the weakest to F5 at the strongest.
On the original Fujita scale winds in the range of 158-206 mph were believed to cause F3 level damage. However, this estimate has since been found to be inaccurate. An the more accurate Enhanced Fujita scale winds for and EF3 tornado are estimated at 136-165 mph.
If by classifications you mean you mean F3, F4 and such, they are categories on the Fujita Scale which rates tornadoes from F0 to F5 based on damage. An F0 causes minor damage, breaking tree branches, taking down gutters, and stripping parts of some roof surfaces. An F5 causes total devastation, wiping houses clean off their foundations, destroying concrete structures, and even peeling the pavement from roads. The categories on the Enhanced Fujita Scale (EF0 to EF5) are essentially the same.
The term "F3" can have different meanings depending on the context. In computing, it often refers to the function key F3, which can be used for various purposes like searching or refreshing a page. In meteorology, F3 is a classification for tornadoes on the Fujita scale, indicating significant damage with wind speeds between 158 and 206 mph. In gaming, F3 may refer to a specific in-game function or shortcut, depending on the game being played.
Referring to "an F3" can mean a couple different things. It may refer to one of a number of plane models including the Panavia Tornado, a fighter jet used by the RAF. It may also refer to a level on the Fujita scale, a system of rating the severity of tornadoes. On this scale the weakest tornadoes are rated F0 while the strongest are rated F5. A rating of F3 indicates a strong tornado capable of leaving well-built houses mostly destroyed.
