Enhanced Fujita scale - Wikipedia
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.
The Enhanced Fujita Scale (EF Scale) - National Weather Service
The Enhanced Fujita Scale or EF Scale, which became operational on February 1, 2007, is used to assign a tornado a 'rating' based on estimated wind speeds and related damage.
Tornado Scale - The Enhanced Fujita Scale | TornadoFacts.net
The enhanced Fujita tornado scale was created by Fujita Scale Enhancement Project between 2000 and 2004. The enhanced Fujita scale still uses the same basic principles as the original Fujita scale. There are six categories of tornadoes, 0 to 5.
Fujita scale - Wikipedia
The Fujita scale (F-Scale; / f u ˈ dʒ iː t ə /), or Fujita–Pearson scale (FPP scale), is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation.

EF Scale - National Weather Service
The EF Scale will still rate tornado categories from zero to five, but the ranges of wind speed in each category are now more accurate. The EF Scale takes into account more variables than the original F Scale did when assigning a wind speed rating to a tornado.
