The Fujita scale (now the Enhanced Fujita scale) which goes from F0 to F5 (EF0 to EF5).
The Fujita scale uses the severity of the damage a tornado causes to determine its rating.
Tornado damage has traditionally been rated on the Fujita scale. However, the United States and Canada now rate tornado damage on the similar Enhanced Fujita scale.
The Fujita scale determines the strength of the tornado based on the severity of the damage it causes. In the U.S. it has been replaced by the Enhanced Fujita scale.
The scale used to identify the severity of a tornado is called the Enhanced Fujita (EF) scale. It ranges from EF0 (weakest) to EF5 (strongest) based on the tornado's estimated wind speeds and resultant damage.
The intensity of a tornado is determined by damage. Damage is examined and the tornado's peak wind speed is estimated. This is used to rate it on the Enhanced Fujita Scale which ranges from EF0 as the weakest to EF5 as the strongest.
Tornadoes do have a scale by which they are rated. It is the Enhanced Fujita scale. However, trackers do not use it to rate the tornado as it occurs. Damage is assessed by experts after the tornado has passed.
There are what can be called Pearson numbers that can be used to rate a tornado's width and the distance it travels, but these are rarely used. In most cases a tornado's width is measured in yards or, if it is a very large tornado, in miles and fractions of a mile (meters and kilometers if you prefer the metric scale).
The Enhanced Fujita scale (EF0 to EF5) is used to rate tornadoes based on the severity of the damage they cause.
No. The Fujita (F) scale uses damage to rate tornadoes and F5 damage is total destruction, leaving no room for a higher category. So the F6 tornado is a purely theoretical idea.
Tornado strength is assessed on the Enhanced Fujita scale. It is not so much a tool as a set of guidelines. Meteorologists and engineers survey the damage done my a tornado, using it to estimate the wind speed at various points along the path. The highest wind speed is used to assign a rating, ranging from EF0 for the weakest tornadoes to EF5 for the strongest.
The Fujita scale, or Fujita intensity scale, is a scale used to rate tornado intensity based on the damage caused by a tornado. It ranges from F0 (weakest) to F5 (strongest) and is no longer in use, having been replaced by the Enhanced Fujita (EF) scale which takes additional factors into account.
Because direct wind measurements are rare and difficult to obtain wind speeds are estimated based on the damage left behind. These estimates are used to rate a tornado on the Enhanced Fujita scale which ranges from EF0 (weakest) to EF5 (strongest).
