The old scale lists an F5 tornado as wind speeds of 261–318 mph (420–512 km/h), while the new scale lists an EF5 as a tornado with winds above 200 mph (322 km/h), found to be sufficient to cause the damage previously ascribed to the F5 range of wind speeds.
Each year, more than 2,000 tornadoes are recorded worldwide, with the vast majority occurring in North America and Europe. [9] In order to assess the intensity of these events, meteorologist Ted Fujita devised a method to estimate maximum wind speeds within tornadic storms based on the damage caused; this became known as the Fujita scale.
The drought began on May 20, 2013, following the dissipation of the 2013 Moore, Oklahoma EF5 tornado. [11] [12] Several tornadoes since the Moore EF5 have reached the 200 miles per hour (320 km/h) wind speeds needed for a tornado to be classified as an EF5, including the 2013 El Reno EF3 tornado and 2015 Rochelle–Fairdale EF4 tornado, with wind speeds measured in excess of 295 miles per hour ...
The study’s authors argue that adjusting the EF5 wind speed threshold downward just 11 mph from 201 mph to 190 mph, or upgrading tornadoes with 190-200 mph estimated winds to EF5, would create a ...
The 2011 Joplin tornado was a large EF5 tornado that devastated Joplin, Missouri, United States, on the evening of Sunday, May 22, 2011.As part of a larger late-May sequence of tornadic activity, the extremely violent tornado began just west of Joplin and quickly reached a peak width of nearly 1 mile (1.6 km) as it tracked through the southern part of the city, before later impacting rural ...
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 Enhanced Fujita scale measures a tornado's intensity on a ...
Eleven years later, it remains the most recent tornado to be rated EF5, the strongest possible rating on the Enhanced Fujita Scale. The 11-year gap is the longest since official U.S. records began ...
The instantaneous velocity readings taken are not directly equivalent to the three-second gust at 33 feet (10 m) that the Enhanced Fujita scale attempts to estimate, but they mark the second-highest wind speed ever recorded in a tornado, after wind speeds of approximately 135 m/s (300 mph) were recorded in both the 1999 Bridge Creek–Moore ...
