'''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. The Fujita scale, Enhanced Fujita scale, and the International Fujita scale rate tornadoes by the damage caused.<ref>[http://www.spc.noaa.gov/faq/tornado/f-scale.html NOAA: Fujita Tornado Damage Scale]</ref><ref>[http://www.tornadofacts.net/tornado-scale.php Tornado Damage Scales: Fujita Scale and Enhanced Fujita Scale]</ref> 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.<ref>{{cite web |last1=Schultz |first1=Colin |title=Here's How the Enhanced Fujita Scale Works, and This Is What It Looks Like |url=https://www.smithsonianmag.com/smart-news/heres-how-the-enhanced-fujita-scale-works-and-this-is-what-it-looks-like-78879392/ |website=Smithsonian Magazine |access-date=2022-09-14}}</ref> An EF0 tornado may damage trees and peel some shingles off roofs, while an EF5 tornado can rip well-anchored homes off their foundations, leaving them bare— even deforming large skyscrapers. The similar TORRO scale ranges from a T0 for extremely weak tornadoes to T11 for the most powerful known tornadoes. Doppler radar data, photogrammetry, and ground swirl patterns (cycloidal marks) may also be analyzed to determine the intensity and assign a rating.

Tornadoes vary in intensity regardless of shape, size, and location, though strong tornadoes are typically larger than weak tornadoes. The association with track length and duration also varies, although longer-track (and longer-lived) tornadoes tend to be stronger.<ref name="width/length intensity relationship">{{cite journal| title = On the Relationship of Tornado Path Length and Width to Intensity| author = Brooks, Harold E.| date = 2004-04-01| journal = Weather and Forecasting |volume = 19| issue = 2| pages = 310–319| doi = 10.1175/1520-0434(2004)019<0310:OTROTP>2.0.CO;2| bibcode = 2004WtFor..19..310B| url = https://zenodo.org/record/1234655| doi-access = free}}</ref> In the case of violent tornadoes, only a small portion of the path area is of violent intensity; most of the higher intensity is from subvortices.<ref name="significant tornadoes">{{cite book |last = Grazulis |first = Thomas P. |title = Significant Tornadoes 1680–1991 |date=July 1993 |publisher = The Tornado Project of Environmental Films |location = St. Johnsbury, Vermont |isbn = 978-1-879362-03-1 }}</ref> In the United States, 80% of tornadoes are rated EF0 or EF1 (equivalent to T0 through T3).

== History of tornado intensity measurements ==

[[File:Fujita scale technical.svg|thumb|right|A diagram of the Fujita scale as it relates to the Beaufort scale and the Mach number scale]]

For many years, before the advent of Doppler radar, scientists relied on educated guesses for tornado wind speed. The only evidence indicating wind speeds found in the tornado was the damage left behind by tornadoes that struck populated areas. Some believed they reach {{convert|400|mph|abbr=off|sp=us}}; others thought they might exceed {{convert|500|mph}}, and perhaps even be supersonic. One can still find these incorrect guesses in some old (until the 1960s) literature, such as the original Fujita intensity scale developed by Dr. Tetsuya Theodore "Ted" Fujita in the early 1970s. However, one can find accounts (e.g. [http://www.stormtrack.org/library/archives/stsep00.htm]; be sure to scroll down) of some remarkable work done in this field by a U.S. Army soldier, Sergeant John Park Finley.

In 1971, Dr. Fujita introduced the idea of a scale to measure tornado winds. With the help of colleague Allen Pearson, he created and introduced what came to be called the Fujita scale in 1973. The F in F1, F2, etc. stands for Fujita. The scale was based on a relationship between the Beaufort scale and the Mach number scale; the low end of F1 on his scale corresponds to the low end of B12 on the Beaufort scale, and the low end of F12 corresponds to the speed of sound at sea level, or Mach 1. In practice, tornadoes are only assigned categories F0 through F5.

The TORRO scale, created by the Tornado and Storm Research Organization (TORRO), was developed in 1974 and published a year later. The TORRO scale has 12 levels, which cover a broader range with tighter graduations. It ranges from a T0 for extremely weak tornadoes to T11 for the most powerful known tornadoes. T0–T1 roughly corresponds to F0, T2–T3 to F1, and so on. While T10–T11 would be roughly equivalent to F5, the highest tornado rated to date on the TORRO scale was a T8.<ref name="TORRO history">{{cite web| url = http://www.torro.org.uk/TORRO/about/history.php| title = A Brief History of TORRO (to 1985)| access-date = 2006-11-01| last = Meaden| first = Dr. Terence| year = 1985| publisher = TORRO}}</ref><ref name="TORRO severe summary">{{cite web| url = http://www.torro.org.uk/TORRO/britwxextremes/summary.php| title = British Weather Extremes Summary| access-date = 2006-11-02| author = Various| publisher = TORRO}}</ref> Some debate exists as to the usefulness of the TORRO scale over the Fujita scale&mdash;while it may be helpful for statistical purposes to have more levels of tornado strength, often the damage caused could be created by a large range of winds, rendering it hard to narrow the tornado down to a single TORRO scale category.

[[File:The National Weather Service Six-Step Wording for the Enhanced Fujita Scale.jpg|thumb|The National Weather Service’s arrow showing the Enhanced Fujita scale. This includes a description word and wind speed range for each level of the scale.]] Research conducted in the late 1980s and 1990s suggested that even with the implication of the Fujita scale, tornado winds were notoriously overestimated, especially in significant and violent tornadoes. Because of this, in 2006, the American Meteorological Society introduced the Enhanced Fujita scale, to help assign realistic wind speeds to tornado damage. The scientists specifically designed the scale so that a tornado assessed on the Fujita scale and the Enhanced Fujita scale would receive the same ranking. The EF-scale is more specific in detailing the degrees of damage on different types of structures for a given wind speed. While the F-scale goes from F0 to F12 in theory, the EF-scale is capped at EF5, which is defined as "winds ≥{{convert|200|mph}}".<ref name="SPC FAQ">{{cite web| url = http://www.spc.noaa.gov/faq/tornado| title = The Online Tornado FAQ| access-date = 2006-09-08| last = Edwards| first = Roger|author-link= Roger Edwards (meteorologist)| date = 2006-04-04| publisher = Storm Prediction Center}}</ref> In the United States, the Enhanced Fujita scale went into effect on February 2, 2007, for tornado damage assessments and the Fujita scale is no longer used.

The first observation confirming that F5 winds could occur happened on April 26, 1991. A tornado near Red Rock, Oklahoma, was monitored by scientists using a portable Doppler weather radar, an experimental radar device that measures wind speed. Near the tornado's peak intensity, they recorded a wind speed of {{convert|115|-|120|m/s|mph+km/h|abbr=off|sp=us}}. Though the portable radar had the uncertainty of ±{{convert|5|-|10|m/s|mph+km/h}}, this reading was probably within the F5 range, confirming that tornadoes were capable of violent winds found nowhere else on earth.

Eight years later, during the 1999 Oklahoma tornado outbreak of May 3, another scientific team was monitoring an exceptionally violent tornado (one which eventually killed 36&nbsp;people in the Oklahoma City metropolitan area). Around 7 p.m., they recorded one measurement of {{convert|301|±|20|mph|km/h}},<ref name="fastest wind">{{cite web| url = http://cswr.org/dow/DOW.htm| title = Doppler On Wheels| access-date = 2006-12-29| author = Center for Severe Weather Research| year = 2006| url-status = dead| archive-url = https://web.archive.org/web/20070205124033/http://www.cswr.org/dow/dow.htm| archive-date = 2007-02-05}}</ref> {{convert|50|mi/h|km/h}} faster than the previous record. Though this reading is just short of the theoretical F6 rating, the measurement was taken more than {{convert|100|ft|m|abbr=off|sp=us}} in the air, where winds are typically stronger than at the surface.{{Citation needed|date=December 2010}} In rating tornadoes, only surface wind speeds or the wind speeds indicated by the damage resulting from the tornado, are taken into account. Also, in practice, the F6 rating is not used.

While scientists have long theorized that extremely low pressures might occur in the center of tornadoes, no measurements confirm it. A few home barometers had survived close passes by tornadoes, recording values as low as {{convert|24|inHg|hPa|abbr=off|sp=us}}, but these measurements were highly uncertain.<ref name="Handy Weather Answer Book">Lyons, Walter A. <u>The Handy Weather Answer Book</u>. Detroit: Visible Ink Press, 1997.</ref> In 2003, a U.S. research team succeeded in dropping devices called "turtles" into an F4 tornado, and one measured a pressure drop of more than {{convert|100|hPa|inHg}} as the tornado passed directly overhead.<ref name="tornado pressure">[https://web.archive.org/web/20060907060637/http://magma.nationalgeographic.com/ngm/0404/feature1/fulltext.html Chasing Tornadoes @ National Geographic Magazine]</ref> Still, tornadoes are widely varied, so meteorologists are still researching to determine if these values are typical or not.

In 2018, the International Fujita scale was created by the European Severe Storms Laboratory as well as other various European meteorological agencies. Unlike the other three scales (Fujita, Enhanced Fujita, and TORRO), the International Fujita scale has overlapping wind speeds within the ratings. The highest tornado rated on the IF scale was the 2021 South Moravia tornado, which was rated an IF4.<ref>{{Cite web |last=Korosec |first=Marko |date=2021-06-25 |title=The most powerful tornado on record hit the Czech Republic, leaving several fatalities and 200+ injured across the Hodonin district |url=https://www.severe-weather.eu/weather-report/europe-severe-weather-tornado-hodonin-czech-republic-mk/ |website=Severe Weather Europe}}</ref>

In the U.S., F0 and F1 (T0 through T3) tornadoes account for 80% of all tornadoes.

A typical tornado has winds of {{convert|110|mph|km/h}} or less, is about {{convert|250|ft|m}} across, and travels about one mile (1.6&nbsp;km) before dissipating.{{citation needed|date=September 2015}} However, tornado behavior is variable; these figures represent statistical probabilities only.

Two tornadoes that look almost the same can produce drastically different effects. Also, two tornadoes that look very different can produce similar damage, because tornadoes form by several different mechanisms and also follow a lifecycle that causes the same tornado to change in appearance over time. People in the path of a tornado should never attempt to determine its strength as it approaches. Between 1950 and 2014 in the United States, 222&nbsp;people have been killed by (E)F1 tornadoes, and 21 have been killed by (E)F0 tornadoes.<ref name=Tornadohistoryproject>{{cite web|title=Search Tornadoes|url=http://www.tornadohistoryproject.com/|archive-url=https://web.archive.org/web/20070110234159/http://www.tornadohistoryproject.com/|url-status=usurped|archive-date=January 10, 2007|website=Tornadohistoryproject.com|access-date=24 June 2015}}</ref><ref name="SPC past tornadoes">"[http://www.spc.noaa.gov/climo/historical.html Climatological or Past Storm Information and Archived Data]."

=== Weak tornadoes ===

Around 60{{ndash}}70 percent <ref>{{Cite web|url=https://www.britannica.com/science/tornado/Tornado-intensity#ref218368|title = Tornado - Tornado intensity}}</ref> of tornadoes are designated EF1 or EF0, also known as "weak" tornadoes. But "weak" is a relative term for tornadoes, as even these can cause significant damage. F0 and F1 tornadoes are typically short-lived; since 1980, almost 75 percent of tornadoes rated weak stayed on the ground for {{convert|1|mi|km}} or less.<ref name="severe plot" /> In this time, though, they can cause both damage and fatalities.

EF0 (T0–T1) damage is characterized by superficial damage to structures and vegetation. Well-built structures are typically unscathed, though sometimes sustaining broken windows, with minor damage to roofs and chimneys. Billboards and large signs can be knocked down. Trees may have large branches broken off and can be uprooted if they have shallow roots. Any tornado that is confirmed, but causes no damage (i.e., remains in open fields) is normally rated EF0, as well, even if the tornado had winds that would give it a higher rating. Some NWS offices, however, have rated these tornadoes EFU (EF-Unknown) due to the lack of damage.<ref>{{cite web |last1=Murphy |first1=John D. |title=National Weather Service Instruction 10-1605 |url=https://www.nws.noaa.gov/directives/sym/pd01016005curr.pdf |publisher=National Weather Service |access-date=6 March 2021 |pages=A–74–75 |date=9 July 2018}}</ref>

EF1 (T2–T3) damage has caused significantly more fatalities than those caused by EF0 tornadoes. At this level, damage to mobile homes and other temporary structures becomes significant, and cars and other vehicles can be pushed off the road or flipped. Permanent structures can suffer major damage to their roofs.{{citation needed|date=January 2023}}

{{Gallery |title=Weak tornadoes |width=160 | height=170 |align=center |File:Sunset Beach EF0 damage.jpg |EF0 damage: This house only sustained a minor loss of shingles. Though well-built structures are typically unscathed by EF0 tornadoes, falling trees and tree branches can injure and kill people, even inside a sturdy structure. Between 35 and 40% of all annual tornadoes in the U.S. are rated EF0. |File:EF1 damage Richardson, Texas.jpg |EF1 damage: Cause major damage to mobile homes and automobiles, and can cause minor structural damage to well-constructed homes. This frame home sustained major roof damage but otherwise remained intact. Around 35% of all annual tornadoes in the U.S. are rated EF1. }}

=== Significant tornadoes ===

EF2 (T4–T5) tornadoes are the lower end of "significant" yet are stronger than most tropical cyclones (though tropical cyclones affect a much larger area and their winds take place for much longer duration). Well-built structures can suffer serious damage, including roof loss, and the collapse of some exterior walls may occur in poorly built structures. Mobile homes, however, are destroyed. Vehicles can be lifted off the ground, and lighter objects can become small missiles, causing damage outside of the tornado's main path. Wooded areas have a large percentage of their trees snapped or uprooted.{{citation needed|date=January 2023}}

EF3 (T6–T7) damage is a serious risk to life and limb and the point at which a tornado statistically becomes significantly more destructive and deadly. Few parts of affected buildings are left standing; well-built structures lose all outer and some inner walls. Unanchored homes are swept away, and homes with poor anchoring may collapse entirely. Small vehicles and similarly sized objects are lifted off the ground and tossed as projectiles. Wooded areas suffer an almost total loss of vegetation, and some tree debarking may occur. Statistically speaking, EF3 is the maximum level that allows for reasonably effective residential sheltering in place in a first-floor interior room closest to the center of the house (the most widespread tornado sheltering procedure in America for those with no basement or underground storm shelter).

{{Gallery |title=Significant tornadoes |width=160 | height=170 |align=center |File:WelchEF2Damage2012.jpg |EF2 damage: At this intensity, tornadoes have a more significant impact on well-built structures, removing the roofs, and collapsing some exterior walls of poorly built structures. EF2 tornadoes are capable of destroying mobile homes and generating large amounts of flying debris. This home completely lost its roof, but its walls remained intact. Between 15 and 19% of all annual tornadoes in the U.S. are rated EF2. |File:January 23, 2012, Center Point, Alabama tornado damage.JPG |EF3 damage: Here, the roof and all but some inner walls of this frame home have been demolished. While taking shelter in a basement, cellar, or inner room improves one's odds of surviving a tornado drastically, occasionally even this is not enough. EF3 and stronger tornadoes only account for about 6% of all annual tornadoes in the United States, yet since 1980, they have accounted for more than 75% of tornado-related deaths. }}

=== Violent tornadoes ===

EF4 (T8–T9) damage typically results in a total loss of the affected structure. Well-built homes are reduced to a short pile of medium-sized debris on the foundation. Homes with poor or no anchoring are swept completely away. Large, heavy vehicles, including airplanes, trains, and large trucks, can be pushed over, flipped repeatedly, or picked up and thrown. Large, healthy trees are entirely debarked and snapped off close to the ground or uprooted altogether and turned into flying projectiles. Passenger cars and similarly sized objects can be picked up and flung for considerable distances. EF4 damage can be expected to level even the most robustly built homes, making the common practice of sheltering in an interior room on the ground floor of a residence insufficient to ensure survival. A storm shelter, bomb shelter, reinforced basement, or other subterranean shelter can provide substantial safety against EF4 tornadoes.<ref>{{Cite web |title=Tornado Safe Rooms |url=https://tornado-strong.org/fact-sheet/choosing-the-right-safe-room-for-you/ |archive-url=https://web.archive.org/web/20230317162344/https://tornado-strong.org/fact-sheet/choosing-the-right-safe-room-for-you/ |archive-date=March 17, 2023 |access-date=2023-07-19 |website=Tornado Strong |language=en-US}}</ref>

EF5 (T10–T11) damage represents the upper limit of tornado power, and destruction is almost always total. An EF5 tornado pulls well-built, well-anchored homes off their foundations and into the air before obliterating them, flinging the wreckage for miles, and sweeping the foundation clean. Large, steel-reinforced structures such as schools are completely leveled. Tornadoes of this intensity tend to shred and scour low-lying grass and vegetation from the ground. Very little recognizable structural debris is generated by EF5 damage, with most materials reduced to a coarse mix of small, granular particles and dispersed evenly across the tornado's damage path. Large, multiple-ton steel frame vehicles and farm equipment are often mangled beyond recognition and tossed miles away or reduced entirely to unrecognizable parts. The official description of this damage highlights the extreme nature of the destruction, noting that "incredible phenomena will occur"; historically, this has included such displays of power as twisting skyscrapers, digging up large trenches into the ground, ripping roofs off of tornado bunkers, collapsing heavy oil rigs, leveling entire communities, derailing and tossing several train cars, and stripping asphalt from roadbeds. Despite their relative rarity, the damage caused by EF5 tornadoes represents a disproportionate hazard to life and limb; since 1950 in the United States, only 60 tornadoes (0.1% of all reports) have been designated F5 or EF5, and yet these have been responsible for more than 1,300 deaths and 14,000 injuries (21.5 and 13.6%, respectively).<ref name="severe plot" /><ref>{{Cite web |url=http://www.norman.noaa.gov/nsww/wp-content/uploads/2012/03/LaDue_NSWW2012.pdf |title=Discriminating EF4 and EF5 Tornado Damage |last1=LaDue |first1=Jim |last2=Marshall |first2=Tim |last3=Scharfenberg |first3=Kevin |date=March 2012 |access-date=2025-03-05 |archive-date=2013-02-20 |archive-url=https://web.archive.org/web/20130220141245/http://www.norman.noaa.gov/nsww/wp-content/uploads/2012/03/LaDue_NSWW2012.pdf |url-status=dead}}</ref>
