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." At this site: http://www.spc.noaa.gov/efscale/
Meteorologists 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.
It 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
Tornadoes 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.
For 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)
Tornadoes 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.
Tornadoes 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.
Tornado 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.
The tornado classification scale is called the Enhanced Fujita Scale (EF Scale). It categorizes tornadoes based on the damage they cause, ranging from EF0 (weakest) to EF5 (strongest).

What does the E mean in tornado classification?
The "E" in the Enhanced Fujita Scale (EF-Scale) used for tornado classification stands for "Enhanced." This scale categorizes tornadoes based on estimated wind speeds and associated damage, providing a more accurate and detailed classification system compared to the original Fujita Scale.
What does the E stand for in EF2 tornado?
The "E" in EF2 tornado stands for Enhanced Fujita Scale, a classification system used to measure tornado intensity based on the damage they cause. The EF scale ranges from EF0 (weakest) to EF5 (strongest).
What is the name of the scale used to rate tornado damage?
The Enhanced Fujita Scale (EF-Scale) is used to rate tornado damage based on the intensity of the tornado and the associated damage caused. It ranges from EF0 (weakest) to EF5 (strongest).
Is an F9 tornado real?
Yes, an F9 tornado is real. However, it is not officially recognized as a standard classification in the Enhanced Fujita Scale, which categorizes tornadoes based on their intensity and damage. The scale currently goes up to an EF5 tornado.
What is the name of the scale used to find out how strong the tornado cell is?
The scale used to measure the strength of a tornado is called the Enhanced Fujita Scale (EF-Scale). It categorizes tornadoes based on the damage caused, ranging from EF0 (weakest) to EF5 (strongest).
What is the classification of a tornado?
Tornadoes are classified based on the Enhanced Fujita (EF) Scale which ranges from EF0 (weakest) to EF5 (strongest). The classification is determined based on the estimated wind speeds and resulting damage caused by the tornado.
What does the E mean in tornado classification?
The "E" in the Enhanced Fujita Scale (EF-Scale) used for tornado classification stands for "Enhanced." This scale categorizes tornadoes based on estimated wind speeds and associated damage, providing a more accurate and detailed classification system compared to the original Fujita Scale.
Is an F12 a tornado?
No, an F12 is not a tornado classification. The Fujita scale, now referred to as the Enhanced Fujita Scale, goes up to F5 for the most intense tornadoes. An F12 rating does not exist in tornado classification systems.
What does the E stand for in EF2 tornado?
The "E" in EF2 tornado stands for Enhanced Fujita Scale, a classification system used to measure tornado intensity based on the damage they cause. The EF scale ranges from EF0 (weakest) to EF5 (strongest).
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 is the name of the scale used to rate tornado damage?
The Enhanced Fujita Scale (EF-Scale) is used to rate tornado damage based on the intensity of the tornado and the associated damage caused. It ranges from EF0 (weakest) to EF5 (strongest).
Which classification of tornado on the Fujita scale does the most damage?
A tornado classified as EF-5 on the Enhanced Fujita Scale causes the most damage. These tornadoes have wind speeds of over 200 mph and are capable of destroying well-built homes and leveling entire neighborhoods.
What scale is use to measure the strength of a tornado and how did it gets its name?
The Enhanced Fujita Scale (EF Scale) is used to measure the strength of a tornado. Its name honors Dr. Ted Fujita, a meteorologist who was a pioneer in tornado research and developed the original Fujita Scale in the 1970s.
What does the f stand for in f scales for tornadoes?
The "F" in tornado classification scales, such as the Fujita scale or the Enhanced Fujita scale, stands for Dr. Tetsuya Theodore Fujita, a Japanese-American meteorologist known for his research on severe convective storms, tornadoes, and microbursts.
What is the name of the scientist who is credited for inventing the tornado scale?
Dr. Tetsuya Theodore Fujita.
