The F scale has been found extremely inaccurate. The size of the tornado does not determine the wind speeds or the damage that will be done. The EF scale is based only by damage, and from surveying the damage, they estimate what the wind speeds were considering it's nearly impossible to get an exact measurement.
Even though this is not rated EF-5, a tornado as narrow as this one can be an EF-5. There are narrow EF-5 and F5 tornadoes. Big wide wedge tornadoes are not always strong either, one of the widest tornadoes recorded was only rated EF-2. The Eli Manitoba tornado in Canada was rated F5 and it was a narrow tornado that had a tight rotation similar to the tornado in this video.
A fast spinning tornado with a small, tight core. A tighter core allows it to get ridiculously quick spins, so a "smaller size" drillbit can produce the wind speeds of its larger counterparts.
The damage that a tornado causes corresponds a scale the Enhance Fujita scale which use to be called Fujita. Based on that damage that the twister causes is then given a EF rating from 0 to 5 based what destruction it caused. Sometimes a tornado can have multiple EF ratings which makes it harder to determine its strength.
Basically, it's got a tight enough rotation that as opposed to using it's strength to wedge out the way larger ones do, it maintains a hard, tight spiral. Stronger winds in a tight formation give you a wicked fast spin like this one, hence it being called a drill bit.
its not the size that determines the classification on the tornadoes.. An EF5(F5) tornado can be as thin as a rope or as wide as 1.5 mile(1 km) its all about how much it can dammage and how fast it spins around its core.
the old fujita scale(F0-5) was determined with size, speed and damage,im not sure how if differences from the new EFscale. an F5 tornado was always shown in pictures as a mile wide wedge,and F0 ones was always shown as thin ropes,.but now im not quite sure how they really rate them,because now ,even the largest and strongest ones seems to be rated EF0 as long as they dont hit towns and structures
The severity of the damage counts. A tornado causing moderate damage to even hundreds of buildings might not be EF rated as high as one that completely obliterates whatever it touches, even if thats only a dozen buildings.
That's kinda obvious. I think he was just judging by how fast the tornado was moving. Tornado strength does not depend on size. I have seen large wedge tornadoes being rated as low as EF1 in my area, and tiny tornadoes only 100 yards wide rated EF5 in Oklahoma. If a tornado remains over an open field, the damage cannot be surveyed as there are no structures or trees in open fields. Tornadoes that do not touch trees, homes, or other structures, they are rated EF0.
Drillbit describes the characteristics of the tornado, I don't believe it's a scientific term or anything like that. Still an extremely intense rotation for that small of a vortex!
I witnessed and experienced the Oakfield tornado of 1996. It looked like it was going to take out my mom and dad's house, but in reality it was about 5 or so miles away. It was forceful and scary and awesome all at the same time. You can still see the path where it went, because the trees that were there are gone, and all new, smaller ones in their place.
That's incorrect. It's categorized by only wind speeds. The damage is used as evidence to help determine the speeds of the sustained winds within a tornado.
Tnikster was implying that EF5 wind speed could be caused by something other than an EF5 tornado, which is incorrect. Nothing wrong with my answer. I did not imply that a tornado that causes no damage would ever be classified as EF5.
A tornado like this certainly has the rotation speed to qualify as an EF-5 but if this thing were to be in a city it would be eliminated fairly quickly, the strength obviously wasn't there. Very cool video.
This video show's it? Its a small/thin but intense circulation on the ground. Like a drill-bit. You can have Tornadoes (and land/water spouts) that are of the same width but have weaker winds and thus are not drill-bit tornadoes and simply a weak tornado or spout (of the EF0-EF1 range)
He stated EF5 wind speeds, not that it was an EF5. It's not the SIZE of the tornado that determines where it fits on the scale. It's based on the wind SPEEDS.
That is going to be a classic! We all dream of seeing that, nobody was hurt and there was no damage to anything. Many thanks for your risk and the upload!
They rate the tornado off of what damage it did. And they then calculate the wind speeds to give it an ef rating. So its both damage and wind speeds that they use to determine the rating.
Very true...I've noticed that filming other things, a lot of digital cameras will only shoot at 32-33 fps, and it's just physically impossible to really see and comprehend things moving THAT fast when you're only capturing half the frames per second your eyes can see. One of my better quality cams is an old shoulder VCR camera, seems like almost full 60 fps capture speed...you get amazingly smooth video out of it.
You are also wrong! Tornadoes are not based off wind speed but damage caused according to the Enhanced Fujita Scale... The different EF classes have a range of wind speeds that gives people the assumption that this is how they are classified

"Probably has wind speeds approaching the speed of sound on the small space/time scales." - Reed
"Storm chasers ought to have a firm grasp of what the different tornado types are that they encounter." And they do. The wind speeds could have very well been on an EF5 lvl.
I sorry, but this was no EF-5, not even close. EF-5s are much larger and usually muti vortex. I just lived thru an EF-4 here in Henryville, IN and it was far larger then this one. There is little chance this tornado could have the sustained winds required for EF-5 status.
The Fujita scale is a tornado damage scale, not a tornado intensity scale. Nevertheless this is an impressive video. The tornado in the video is probably capable of EF2 damage. EF5 damage is generally produced by much larger funnels - I think the small diameter of this one makes the windspeed look greater than it actually is.
Only because there was nothing for it to break. Had this started up in the middle of a small town on main street, you would be saying something entirely different.
ef5 i think is the roughess tornado .. but and ef5 is bigger than this .. but i think he was talking about the wind speed .. ef5 is like 70+ miles ( 100+ kilometers)
I completely understand how the scale works, but to say this is an EF-5 as this person did, without any damage reports at the time was just shear excitement. I'm not not give the guy a hard way or anything, only stating what looked to be really the fact. After looking up the aftermath classification on this tornado it t6urns out that I was correct. It was an EF-3, which was still more powerful than I thought it was.
Seeing as its a physical impossibility to measure the wind speed of a tornado while it's on the ground rotating, any scientists would be hard pressed to use a scale based on something they couldn't accurately measure.
size has nothing to do with it... e.g if there was an f 0 somehow 3 miles wide and it went over a town once they check the damage they would class it as ef-0 considering it only did the amount of damage and hence has the windspeed of an ef-0?
EF5 generally has a mile wide base if not larger., as tommyboy stated.. it's based on the windspeed.. not size... and I agree with this person.. speculation does bring others down.. this sure doesn't. amazing audio on it though.
Did someone from NWS officially classify this Tornado? Tornadoes are rated by damage caused and what NWS surveyors see when they do a survey after. Only then is it classified EF-0 to EF-5. Also, since this was posted by TVN, I would tend to think these are professional chasers. I base my comments on the fact I am an 11 year plus Skywarn Spotter with Advanced Spotter certification. Be Well and Be Safe. :-)
One house, a thousand houses; it doesn't matter. Windspeed is the name of the game with tornadoes. A tornado doesn't HAVE to be a mile wide to be an EF5....for instance if you google the Pampa Texas tornado, or Elie Manitoba tornado, you will see very thin tornadoes which were both rated f5 and destroyed alot of property.
Okay, you go grab a camera...get 150 yards of something spinning violently enough to pick you up and chuck you into the Netherrealm, feel the pressure differential burst your ear drums as it rolls over your tank car, see a tornado rip right through the middle of a semi-truck and keep rolling. Get all of that footage yourself, in person, and we'll see how quiet you are on the other end of that camera.
I do. but it would eventually take out some few houses - nothing if you compare to an EF5 tornado that is able to destroy a whole city with hundreds or thousands of houses

The headlines the nest day would read, "Search continues for remains of person who ran into tornado."
The F scale has been found extremely inaccurate. The size of the tornado does not determine the wind speeds or the damage that will be done.

This tornado spins SO FAST that it looks like the video is Fast Forwarded XD
DID YOU SEE THE ROTATION OF THAT THING!!?!!?!!?!!?!
A fast spinning tornado with a small, tight core. A tighter core allows it to get ridiculously quick spins, so a "smaller size" drillbit can produce the wind speeds of its larger counterparts.

Sometimes a tornado can have multiple EF ratings which makes it harder to determine its strength.
That rotation is INCREDIBLE!
Reminds me of the Elie tornado in Manitoba, Canada a couple years back. That had a bit bigger base than this (300m or so?) but it was a tiiiiiny EF5.
well it was clearly going all "FUCK YOU GRASS, TAKE THIS.. AND THIS!!" at 1:26
Basically, it's got a tight enough rotation that as opposed to using it's strength to wedge out the way larger ones do, it maintains a hard, tight spiral. Stronger winds in a tight formation give you a wicked fast spin like this one, hence it being called a drill bit.
its not the size that determines the classification on the tornadoes..
An EF5(F5) tornado can be as thin as a rope or as wide as 1.5 mile(1 km) its all about how much it can dammage and how fast it spins around its core.
The reason it was not rated ef5 was because it only destroyed grass no structures were therefore they had nothing to go by to give a higher rating
Ok, that was freaking amazing!, tornado's rotation is just insane!
Its a too bad if a 300 mph wind tornado is rated EF0 because it dont hits anything
the old fujita scale(F0-5) was determined with size, speed and damage,im not sure how if differences from the new EFscale. an F5 tornado was always shown in pictures as a mile wide wedge,and F0 ones was always shown as thin ropes,.but now im not quite sure how they really rate them,because now ,even the largest and strongest ones seems to be rated EF0 as long as they dont hit towns and structures
Awesome tornado and a surprisingly good shot of the core winds. Bravo!
If you look closely , you can see cattle running away from the tornado
The severity of the damage counts. A tornado causing moderate damage to even hundreds of buildings might not be EF rated as high as one that completely obliterates whatever it touches, even if thats only a dozen buildings.
Can somebody explain to me the term drillbit? i've never heard of it before
If that thing would've hit any house or something.. damn! Those windspeeds are extreme. I'm sure it would have been an EF5+ if it did any damage.
That's kinda obvious. I think he was just judging by how fast the tornado was moving. Tornado strength does not depend on size. I have seen large wedge tornadoes being rated as low as EF1 in my area, and tiny tornadoes only 100 yards wide rated EF5 in Oklahoma.

Tornadoes that do not touch trees, homes, or other structures, they are rated EF0.
One of the most violent ropes I have ever seen.
This could easily be an F5 ....there have been F5 tornadoes this size many times before. For example the pampa texas tornado.
Holy crap I thought it was sped up but I guessed wrong!! :O
Drillbit describes the characteristics of the tornado, I don't believe it's a scientific term or anything like that. Still an extremely intense rotation for that small of a vortex!

If you listen closely he was specifically referring to the rotation speed.
the EF scale is a DAMAGE scale, not a WIND scale. You can have a tornado with EF5-level winds get rated EF1 if it doesn't hit anything but grassland.
A tornado like this certainly has the rotation speed to qualify as an EF-5 but if this thing were to be in a city it would be eliminated fairly quickly, the strength obviously wasn't there. Very cool video.

It's not wind speed that gives rating. It is the amount of damage that the tornado causes.
That is one intense tornado!!
He stated EF5 wind speeds, not that it was an EF5. It's not the SIZE of the tornado that determines where it fits on the scale. It's based on the wind SPEEDS.
sounds like she said.. "look at it rope out" ?
Wow! That was amazing!!!
That is going to be a classic! We all dream of seeing that, nobody was hurt and there was no damage to anything. Many thanks for your risk and the upload!
Actually it's more of combination of wind speeds and damage that determines the rating of a tornado.
Incredible video, you guys! Wow!
Go GET IT! I would have ran into that field after it.
What's a Drill-Bit tornado? I've heard the term before, just dont know what it is.
They rate the tornado off of what damage it did. And they then calculate the wind speeds to give it an ef rating. So its both damage and wind speeds that they use to determine the rating.
Thanks for the feedback! :D
According the the NWS, the wind speeds did at no time reach EF-5 status.
Very true...I've noticed that filming other things, a lot of digital cameras will only shoot at 32-33 fps, and it's just physically impossible to really see and comprehend things moving THAT fast when you're only capturing half the frames per second your eyes can see.
One of my better quality cams is an old shoulder VCR camera, seems like almost full 60 fps capture speed...you get amazingly smooth video out of it.
Awesome Vid. Were ya'll scared and excited at the same time. You were so close to the Vortex.
Wow, that's VIOLENT rotation. Reminds me of the Elie, Manitoba tornado
Amazing footage!
Man that thing's got some wind speed. D:
That was the F5 that hit Andover, KS back in 1991.
so lets say, if a mile wide EF5 tornado never hits anything, buildings etc, its classified as a EF0?? I dont think so.??
What is a drillbit tornado?
Size doesn't matter with these things, it's speed and this twister is hauling ass! Amazing rotation!
You are also wrong! Tornadoes are not based off wind speed but damage caused according to the Enhanced Fujita Scale... The different EF classes have a range of wind speeds that gives people the assumption that this is how they are classified
"Probably has wind speeds approaching the speed of sound on the small space/time scales." - Reed
it only few secs, wher tha full video?
It's a good thing that was in an empty field and not in a developed area. Imagine the damage it could have done.
"Storm chasers ought to have a firm grasp of what the different tornado types are that they encounter." And they do. The wind speeds could have very well been on an EF5 lvl.
he said ef5 wind speeds oncinuating that it has the wind speeds that a ef-5 tornado would have.
But if it was producing EF5 damage (hence EF5 wind speed), it would - by definition - be an "EF5 tornado".
I sorry, but this was no EF-5, not even close. EF-5s are much larger and usually muti vortex. I just lived thru an EF-4 here in Henryville, IN and it was far larger then this one. There is little chance this tornado could have the sustained winds required for EF-5 status.
the speed of that thing was awesome to see.
dude, that is sick!!! great video!!
The ratings are based on wind speed. The width doesn't matter.

EF5 damage is generally produced by much larger funnels - I think the small diameter of this one makes the windspeed look greater than it actually is.
Actually, it was just a closeup of someone using a drill bit in their back yard.
Fantastic video!
Only because there was nothing for it to break. Had this started up in the middle of a small town on main street, you would be saying something entirely different.
That is amazing! You all are so brave.
awsome footage but its not a e-f-5
ef5 i think is the roughess tornado .. but and ef5 is bigger than this .. but i think he was talking about the wind speed .. ef5 is like 70+ miles ( 100+ kilometers)

That seriously is so cool looking lol
Seeing as its a physical impossibility to measure the wind speed of a tornado while it's on the ground rotating, any scientists would be hard pressed to use a scale based on something they couldn't accurately measure.
Maybe because Heidi Farrar is a more seasoned chaser than you will ever be?
size has nothing to do with it... e.g if there was an f 0 somehow 3 miles wide and it went over a town once they check the damage they would class it as ef-0 considering it only did the amount of damage and hence has the windspeed of an ef-0?

It lacked the size for an EF5, perhaps it was an EF2 at most.
Except, by definition, if it doesn't cause any damage, they can't call it that. Your answer, fail.
terrible tornado.....really extreme =)
its long and sharp in shape i guess and it is revolving very fast
Drill bit? So some tornadoes form diamonds when they touch down?

that was an EF5?...it didn't hit anything.
I do. but it would eventually take out some few houses - nothing if you compare to an EF5 tornado that is able to destroy a whole city with hundreds or thousands of houses
i think he said EF 5 in context to the wind speed.
And the amount of damage it does.
Right?? Exactly what I said! Glad there are no deaths that I know of as of yet.
the tornado was all "Dont mind me, just passing by "
I have never seen a tornado in real life. What I wouldn't give to be able to see one of these dancing on the plains.
trust me. that tornado would take out a house in about 1 second. it would pop it like a balloon
what would happen if you just ran into that thing
Damn this tornado is BEAUTIFUL!
isn't it the desruction?
Oh my ! ahhhhhh an EF5 can be that thin? wow I never knew!
it's damage that gives a tornado its rating not wind speed.... hurricanes are classified based on wind speed...
