The Fujita ("F") scale is based on the severity of the damage which is used to provide a basic wind speed estimate. It uses this technique because when the was created in 1971 we had no means of obtaining direct wind measurements from inside a tornado. More recently in 2007 the wind speed estimates have been adjusted to more accurately correspond with the damage levels. This is called the Enhanced Fujita ("EF") scale. Although it is now possible to get direct wind measurements from a tornado, such measurements are rare and difficult to obtain so that only a handful of tornadoes have such measurements taken. So damage must still be used as that primary means of rating tornadoes.
Damage
Fujita released the scale in 1971, but much of the development was based on a detailed survey of the Lubbock, Texas tornado of 1970.
The Fujita scale is a system of rating the intensity of tornadoes from F0 at the weakest to F5 at the strongest. The scale is based based on the severity of damage that the tornado causes. As of February 1, 2007 all new tornadoes in the United States are rated on the Enhanced Fujita scale (EF0 to EF5), but the ratings remain essentially the same.
Theodore Fujita develop the fujita scale in 1971
The Fujita scale is named after the scientist who invented it: Dr. Tetsuya Theodore Fujita.
The Fujita scale classifies tornadoes based on damage.
The Fujita scale is a scale of tornado intensity based on damage to man-made structures and vegetation.
It doesn't. The Fujita scale classifies tornadoes based on the severity of the damage they cause.
Damage
by scale called the fujita scale or (enhanced fujita scale) to measure intensity or strength of a tornado based on the severity of damage.
The F stands for Fujita as in the Fujita scale, which was invented in 1971 by Tetsuya Theodore Fujita. The Fujita scale measures the intensity of tornadoes from F0 to F5 based on damage.
The Fujita Scale is a scale that rates the intensity of tornadoes from F0 (weakest) to F5 (strongest) based on the severity of damage done.
The Fujita scale is used to rate the intensity of tornadoes from F0 to F5 based on damage. It is named for its creator Dr. Tetsuya Theodore Fujita.
Fujita released the scale in 1971, but much of the development was based on a detailed survey of the Lubbock, Texas tornado of 1970.
The Enhanced Fujita scale is used to measure the intensity of tornadoes based on the severity of the damage they cause.
Both scales assess the intensity of a tornado based on the severity of the damage it causes. The ratings on the Fuijta and Enhanced Fujita scale are equivalent. For example a tornado rated F2 on the Fujita scale would probably be rated EF2 on the Enhanced Fujita scale.
