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.
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.
In their analysis, it was determined all three tornadoes caused damage well-beyond their assigned EF-scale ratings, with all three tornadoes having EF5-intensity winds. At the end of the analysis, the researchers stated, "the lofting wind speeds given by this model are much higher than the rating based on the ground survey EF-scale assessment.
These new findings could help untangle critical questions about tornado formation and structure, how wind speeds in the air correspond to damage on the ground and the factors that can cause ...
The International Fujita scale (abbreviated as IF-Scale) is a scale that rates the intensity of tornadoes and other wind events based on the severity of the damage they cause. [1] It is used by the European Severe Storms Laboratory (ESSL) and various other organizations including Deutscher Wetterdienst (DWD) and State Meteorological Agency (AEMET).
Wind speeds over 75 miles per hour are classified as ... powerful enough to uproot trees and cause the widespread damage seen in Bloomington today. White said the storm was an MCS, or mesoscale ...
The Fujita scale, Enhanced Fujita scale, and the International Fujita scale rate tornadoes by the damage caused. [1] [2] In contrast to other major storms such as hurricanes and typhoons, such classifications are only assigned retroactively. Wind speed alone is not enough to determine the intensity of a tornado. [3]
"When assessing a claim for wind damage caused by a storm, insurers will often look to understand if the wind was strong enough to damage an otherwise well-maintained property." The ABI said every ...
