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. None of the tornadoes in the United States recorded before February 1, 2007, were re ...
The new scale more accurately matches wind speeds to the severity of damage caused by the tornado. [8] Though each damage level is associated with a wind speed, the Fujita scale is effectively a damage scale, and the wind speeds associated with the damage listed are not rigorously verified.
Tornado intensity is the measure of wind speeds and potential risk produced by a tornado. Intensity can be measured by in situ or remote sensing measurements, but since these are impractical for wide-scale use, intensity is usually inferred by proxies , such as damage.
What is an EF5 tornado? An EF5 rated tornado has wind speeds of 201 mph or greater. According to the weather service, some of the descriptions of damage include: "Well constructed homes are swept ...
The most extreme tornadoes can attain wind speeds of more than 480 kilometers per hour (300 mph), can be more than 3 kilometers (2 mi) in diameter, and can stay on the ground for more than 100 km (62 mi). [3] [4] [5] Various types of tornadoes include the multiple-vortex tornado, landspout, and waterspout. Waterspouts are characterized by a ...
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 ...
An EF1 tornado has wind speeds ranging from 86 to 100 mph. An EF2 tornado has wind speeds ranging from 111 to 135 mph, and winds of that force can cause some significant damage.
Late-May 1998 tornado outbreak and derecho – DOW recorded maximum wind speeds at 264 mph (425 km/h) at 160 ft (49 m) above ground level, which the NWS classified at almost ground level. Such wind speeds would fall well into the EF5 range on the Enhanced Fujita Scale, though the maximum damage intensity observed in the town of Spencer was F4.
