An EF5 rating on the new scale requires a higher standard of construction in houses than does an F5 rating on the old scale. So, the complete destruction and sweeping away of a typical American frame home, which would likely be rated F5 on the Fujita scale, would be rated EF4 or lower on the Enhanced Fujita scale.
EF0: 65-85 mph. EF1: 86-110 mph. EF2: 111-135 mph ... EF5: Over 200 mph. EF5 tornadoes in Oklahoma. Since 1905, NWS has tracked 13 EF5 tornadoes in Oklahoma, including the devastating 2013 Moore ...
An EF0 tornado may damage trees and peel some shingles off roofs, while an EF5 tornado can rip well-anchored homes off their foundations, leaving them bare— even deforming large skyscrapers. The similar TORRO scale ranges from a T0 for extremely weak tornadoes to T11 for the most powerful known tornadoes.
Tornadoes are ranked from EF0 to EF5. The scale is divided into six categories: F0: Gale; 65 to 85 mph. F1: Weak; 86 to 110 mph. F2: Strong; 111 to 135 mph. F3: Severe; 136 to 165 mph.
An F0 or EF0 tornado, the weakest category, damages trees, but not substantial structures. An F5 or EF5 tornado, the strongest category, rips buildings off their foundations and can deform large skyscrapers. The similar TORRO scale ranges from T0 for extremely weak tornadoes to T11 for the most powerful known tornadoes. [12]
What's the difference? There are six categories used by the National Weather Service to classify the rotational speed of tornadoes (EF0-EF5) but just two levels to warn of tornado activity.
The tornado was the first to be rated EF5 on the Enhanced Fujita Scale, as well as the most recent EF5 tornado to hit Kansas. [ note 3 ] [ 50 ] The tornado was also one of the deadliest in Kansas history, along with being the deadliest in the history of Comanche and Kiowa counties.
In 2007, the Enhanced Fujita scale, EF0 through EF5, was developed by a group of experienced and renowned meteorologists and wind engineers to improve how wind speeds are estimated.
