Draft:Criticism of the Fujita and Enhanced Fujita scales Metadata This file contains additional information, probably added from the digital camera or scanner used to create or digitize it.
The Fujita scale was adopted in most areas outside of the United Kingdom. [citation needed] On February 1, 2007, the Fujita scale was decommissioned, and the Enhanced Fujita Scale was introduced in the United States. [7] The new scale more accurately matches wind speeds to the severity of damage caused by the tornado. [8]
The scale has the same basic design as the original Fujita scale—six intensity categories from zero to five, representing increasing degrees of damage. It was revised to reflect better examinations of tornado damage surveys, in order to align wind speeds more closely with associated storm damage.

Here's how tornadoes are rated on the Enhanced Fujita scale and what those ratings mean.
The Enhanced Fujita scale measures a tornado's intensity on a scale of 1 to 5 based on its wind speed estimates and resulting damages.
The scale is intended to be analogous to the Fujita and Enhanced Fujita scales, while being more applicable internationally by accounting for factors such as differences in building codes. In 2018, the first draft version of the IF-scale, version 0.10 was published. This version was based on a 12-step rating scale.
The scale is primarily used in the United Kingdom whereas the Fujita scale has been the primary scale used in North America, continental Europe, and the rest of the world. At the 2004 European Conference on Severe Storms, Dr. Meaden proposed a unification of the TORRO and Fujita scales as the Tornado Force or TF Scale. [ 1 ]
