I found the following information, The Fujita Scale The Fujita Scale is a well known scale that uses damage caused by a tornado and relates the damage to the fastest 1/4-mile wind at the height of a damaged structure. Fujita's scale was designed to connect smoothly the Beaufort Scale (B) with the speed of sound atmospheric scale, or Mach speed (M). Fujita explains explicitly that "F-scale winds are estimated from structural and/or tree damage, the estimated wind speed applies to the height of the apparent damage above the ground."

∙ 8y agoMeteorologists and engineers use the Enhanced Fujita scale or the EF (enhanced Fujita) scale to rate tornadoes. Scientists examine the damage caused by a tornado, which is used to estimated the wind speed. This, in turn, is used to assign a rating to the tornado. The scale ranges from EF0 for the weakest tornadoes to EF5 for the strongest.

∙ 12y agoIt is called the Enhanced Fujita Scale:
EF-0. Light damage
Wind 65 to 85 mph. Causes some damage to siding and shingles
EF-1. Moderate damage
Wind 86 to 110 mph. Considerable roof damage. Winds can uproot trees and overturn single-wide mobile homes. Flagpoles bend.
EF-2. Considerable damage
Wind 111 to 135 mph. Most single-wide mobile homes destroyed. Permanent homes can shift off foundation. Flagpoles collapse. Softwood trees debarked.
EF-3. Severe damage
Wind 136 to 165 mph. Hardwood trees debarked. All but small portions of houses destroyed.
EF-4. Devastating damage
Wind 166 to 200 mph. Complete destruction of well-built residences, large sections of school buildings.
EF-5. Incredible damage
Wind above 200 mph. Well-built residences swept clean off foundations. Significant structural deformation of mid- and high-rise buildings

∙ 12y agoTornadoes are rated on the Enhanced Fujita scale using wind speed estimates derived from damage. The scale runs from EF0 at the weakest to EF5 at the strongest. The levels on the scale with wind speed ranges and typical damage are as follows
EF0: 65-85 mph. Some shingles and metal roofing peeled off, gutters and awnings taken down. Tree branches broken with some weakly rooted trees toppled. Tornadoes in open fields with no damage are also rated EF0.
EF1: 86-110 mph. Houses suffer severe roof damage, trailers badly damaged or overturned, windows broken, garages, barns and porches may collapse.
EF2: 111-135 mph. Roofs completely or mostly torn from well-built houses but most walls remains standing. Trailers completely destroyed. Large trees snapped. Small cars tossed.
EF3: 136-165 mph. Multiple walls collapse in well-built houses, some houses will lose upper stories. Most trees uprooted or snapped. Train cars lifted from tracks.
EF4: 165-200 mph. Well-built houses leveled. Poorly anchored structures carried some distance. Trees debarked.
EF5: over 200 mph. Utter devastation. Well built houses wiped clean off foundations. Large projectiles launched incredible distances. Asphalt peeled from roads. Severe damage to even the strongest structures.

∙ 11y agoFor many years, this was the Fujita scale. In recent years, it's been upgraded and now referred to as the "Enhanced Fujita Scale"...It rates the severity of damage that a tornado caused from EF-0 (minor damage) to EF-5 (Extreme damage)
Wiki User
∙ 13y agoTornadoes are sometimes divided into three groups of severity: weak, significant (or strong), and violent
More typically tornadoes are rated from F0 to F5 on the Fujita scale.
F0 and F1 tornadoes are weak..
F2 and F3 tornadoes are significant.
F4 and F5 tornadoes are violent.

∙ 13y agoTornadoes in the U.S. are classified on the Enhanced Fujita scale based on damage, which runs from EF0 at the weakest to EF5 at the strongest. More than half of all U.S. tornadoes are rated EF0.
Wiki User
∙ 9y agoTornado intensity is rated onf the Enhanced Fujita scale, which replaced the Fujita scale in 2007. This scale creates standards by which tornado damage is assessed. The damage is used to estimate a tornado's wind speed. The tornado is then assigned a rating based on the highest estimated wind speed. Ratings range from EF0 at the weakest to EF5 at the strongest.

What is the name of the scale used to rate tornado damage?
Tornado damage has traditionally been rated on the Fujita scale. However, the United States and Canada now rate tornado damage on the similar Enhanced Fujita scale.
What does the E mean in tornado classification?
The E means Enhanced, as tornadoes in the United States are rated on the Enhanced Fujita or EF scale.
What is the largest fajita scale for a tornado?
The strongest tornado in the Fujita scale is F5.
What is the name of the scale used to find out how strong the tornado cell is?
Its called the enhanced fujita scale...it measures from an EF0 to an EF5 how fast the tornado was spinning. The wind speed is determined by examining damage.
Do tornado trackers have a scale to measure?
Tornadoes do have a scale by which they are rated. It is the Enhanced Fujita scale. However, trackers do not use it to rate the tornado as it occurs. Damage is assessed by experts after the tornado has passed.
What is the classification of a tornado?
Fujita scale http://www.spc.noaa.gov/faq/tornado/f-scale.html
Which classification of tornado on the Fujita scale does the most damage?
The Fujita scale is also known as the 'F Scale' it measures the strength of a tornado on a scale of F-0 to F-5. F5 is the strongest and most damaging
What is the name of the scale used to rate tornado damage?
Tornado damage has traditionally been rated on the Fujita scale. However, the United States and Canada now rate tornado damage on the similar Enhanced Fujita scale.
What is the name of the tornado rating scale?
Tornadoes are rated on the Enhanced Fujita scale, which replaced the Fujita scale in 2007.
What does the E mean in tornado classification?
The E means Enhanced, as tornadoes in the United States are rated on the Enhanced Fujita or EF scale.
What is the largest fajita scale for a tornado?
The strongest tornado in the Fujita scale is F5.

Its called the enhanced fujita scale...it measures from an EF0 to an EF5 how fast the tornado was spinning. The wind speed is determined by examining damage.
What is the name of the scientist who is credited for inventing the tornado scale?
Dr. Tetsuya Theodore Fujita.
What is the scale of the Waco tornado?
The Waco tornado was an F5.
What is a tornado on the Richter scale?
That is impossible as the Richter scale is for measuring earthquakes.
Do tornado trackers have a scale to measure?
Tornadoes do have a scale by which they are rated. It is the Enhanced Fujita scale. However, trackers do not use it to rate the tornado as it occurs. Damage is assessed by experts after the tornado has passed.
Is a land cyclone another name for a tornado?
No. Although some people refer to tornadoes as cyclones this is incorrect. A cyclone is a large scale low pressure system A tornado is a small scale circulation spawned from a thunderstorm. However, there is one type of tornado known as a landspout.
