I couldn't live in Oklahoma. I'd be a nervous wreck every time Spring rolled around. My new boss was in the Joplin tornado. If that ever happens to my hometown I'm packing up and moving to Vermont (or wherever Google suggests) the next day.

I get why he's saying it.

Playing devil's advocate, if the science community is in agreement with the ranking based on strength and destruction, then why change it just because there was a massive tornado that didn't damage anything?

It would seem to reason that giving the higher ranking due to devastation makes sense.

Why should a strong hurricane that stayed out in open water get the same ranking as a Labor Day, Camille, etc., that actually wrecked shite?


Tornados can't be predicted, only conditions that are conducive for their creation can.

We know about Hurricanes well before they make landfall. The strength matters more there because it impacts planning and reactions to the storm.

Tornado ratings are kind of just a post-mortem.

But I do get what he is saying. There should be a dual scale just so people can understand the actual strength of the storm in a historic sense.

The tornado had a gate-to-gate velocity reading of 260 MPH. Strong circulation could be detected up to 18,000 feet above ground level. Had this thing hit civilization it would have destroyed everything in its path. Thankfully it only damaged farmland. However, due to the way tornadoes are rated, this will only be an EF0/EF1.



It’s a problem of the era the scale was created in.

Back when the Fujita scale was made, radar technology had not advanced enough to be able to tell strength and vertical reference of tornadic producing storms.

So, the only way to classify them was by how much damage they inflicted as they passed by.

Nowadays we have better technology, so another classification system, or a rework is necessary.

I thought the "enhanced" part of the enhanced Fujita scale measured by wind speed.

They have gone too far with the “radar indicated” and “debris fields”. I watched the news one night tell me a “radar confirmed” tornado was passing right over my buddies shop. Didn’t even blow the lid off the trash can.

They are crying wolf too much.

The issue here has nothing to do with whether or not this was a tornado. It was 100% a tornado that was verified and tracked via radar. Damage was found right where then radar showed the tornado. I think the only improvement we have to make in regards to debris on radar is continuing to develop an understanding of how the tornado debris signature on radar correlates to the actual tornado. But I don't think that necessarily matters as far as public messaging goes. A tornado is a tornado is tornado when warning the public.

Not sure what the complaint is. It's consistent with the academic underpinnings and scholarship for the Fujita scale.

Works cited:

quote:

Bill : Solid F2.
Melissa : See, now you have lost me again.
Bill : It's the Fujita scale. It measures a tornado's intensity by how much it eats.
Melissa : Eats?
Bill : Destroys.

But what does it matter if a tornado that hits nothing is rated Ef-1 instead of ef-0 or ef-5?


If you are moving and deciding where to build a house, would you be more or less likely to build where there have been numerous F4/F5 tornadoes? If you'd be less likely to build there, then it would be nice to know they happened, even if they only did minimal damage.

Anyone want to play along with this thought experiment?

I'll even give you some hints. 1. We issued a considerable tag tornado warning for this. 2. It is a supercell getting overtaken by a QLCS/embedded within it. 3. Probabilities based off SPC's tornado intensity probability are 96% EF-1+, 77% EF-2+, 38% EF-3+ and 14% EF-4 +. Enjoy!

I took that as to mean why does the grading scale even matter? Does something happen for a F4 tornado that doesn't happen for a F3?

Yeah you don't have to pay your insurance deductible



At least that's what a lot of folks think about hurricanes

And the answer, which is kind of what I figured.

That's the problem with taking radar at face value.

Mercy. That doesn’t even look like a normal tornado on radar.

There was just a similar looking tornadic storm in Texas.





It was spotter confirmed, but had no significant CC drop.

Hopefully, it did minimal damage to property. It will be interesting to see what it is rated as.
