The Enhanced Fujita scale (abbreviated as EF-Scale) is a scale that rates tornado intensity based on the severity of the damage they cause. It is used in some countries, including the United States and France. [ 1 ]

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. When tornado-related damage is surveyed, it is compared to a list of Damage Indicators (DIs) and Degrees of Damage (DoD) which help estimate better the range of wind ...

The TORRO tornado intensity scale (or T-Scale) is a scale measuring tornado intensity between T0 and T11. It was proposed by Terence Meaden of the Tornado and Storm Research Organisation (TORRO), a meteorological organisation in the United Kingdom, as an extension of the Beaufort scale.

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.

Between 1950 and 2022, only 25 people have been killed by F0 or EF0 tornadoes in the United States. Despite this, tornadoes of this intensity are by far the most common. It’s estimated that about 53% of all tornadoes are classified as EF0 worldwide according to the …

2021年8月17日 · A tornado is assigned a rating from 0 to 5 on the Enhanced Fujita Scale to estimate its intensity in terms of damage and destruction caused along the twister’s path.

categorize each tornado by its intensity and its area; estimate a wind speed associated with the damage caused by the tornado; Dr. Fujita and his staff showed the value of the scale's application by surveying every tornado from the Super Outbreak of April 3-4, 1974.

2020年4月9日 · Fujita's scale, which ranges from F0 to F5, is based upon the type and severity of damage the tornado produced. At that time, there were very few actual measurements of tornado wind speeds that...

2022年5月11日 · EF-0: EF-0′s are the weakest tornadoes. An EF-0 tornado has max wind speeds of 65-85 mph. Typically with an EF-0, damages include shingles or portions of a roof peeled off, gutter and...
