This is crazy cool! Thank you for making this freely available to watch!
I only understood about 35%, but I'd love to learn more! I'm also going to use 'vorticity' in as many conversations as possible. Subscribed!
My thoughts exactly haha
I've been watching a lot of storm chaser videos lately and started wanting to learn more about mesocyclones, supercells, updrafts and downdrafts etc and this video is pure gold 🥇👏. This is why I ❤ simulation and visualization. So fascinating 🤓
I instantly subscribed, what a beautiful representation of a supercell and tornado! I especially like how it depicts streamwise vorticity along the FFD boundary.
That's really amazing stuff. Well done. Thank you for sharing.
More people have to see this..
It deserves more views...excellent representation...!
i don’t know how this doesn’t have more views. this is surely groundbreaking. thank you for sharing this!
Thank you! See some more recent talks for even more coolness :) orf.media/education
The visual at 5:31 could clearly be seen in the Andover tornado drone footage. It was extremely violent.
This has already been mentioned, but so much of this can be seen in the April 2022 Andover drone footage, making this even more incredible. Awesome work!
4:20 beautiful rendering, looks like a beating heart
Happy 420, everyone! :^D
Those very precise and detailled models are only possible because there are stormchasers and others, who have been working for decades - and still do so - often risking their lifes, to help to improve the general knowledge about Tornados, to reduce the advance warning time and consequently to save lifes. I salute you, stormchasers!
This is incredible. Exactly what RUclips is for!
Great, thank you
Wow. Physics in a box has never looked cooler.
I can't imagine the amount of computing power that is needed in order to run something like this. Looks like a ton of input and different variables being interpreted in such a short amount of time
It's actually a tiny amount of input... just a butt-ton of calculation and output
..can produce the moving equivalent of a nuclear bomb...
Testing of weather weapons based on the pulsed subcritical reaction of plutonium began in the USA in the mid-50s. This is why there is no PUBLIC radiology network in the US. Weather drones were at first primitive balloons with difficult radio control, but scientific progress has taken its toll and today they are incredibly effective.

When you look at ANOTHER mushroom cloud of a supercell, does it HINT TO YOU ANYTHING? Then just take dosimeters and run to check the gamma level)))
Oppengamer was the first to believe in gamma weapons, then he convinced the generals of the HIDDEN power of weather weapons based on PULSE nuclear reactions...and then the race began for “weapons-grade” plutonium supposedly to counter the Soviets... that’s very briefly)
The generals were also shocked, but Oppy easily convinced them of the reality of this thing. Then it’s a matter of technology and finance...
Plutonium core based meteodrones use HIGH RADIATION GAMMA IMPULSE for provokation HUGE water condensed process in previosly still atmosphere...meansured, please), GAMMA LEVEL near typical "supercell"
It is necessary to measure gamma AT THE BEGINNING of the supercell formation process - while the drones are ACTIVE. This is the first half hour.
The plutonium core of the meteodrone generates powerful radial gamma pulses in the dew point layer and this gives the PRIMARY impetus to the entire process of creating a pressure/temperature gradient.
Gamma radiation ionizes moist air, it condenses into a powerful cloud, a pressure gradient arises and the supercell mechanism is activated - warm air from all sides tends to the center of the format.
Has anyone asked the feds why there is no PUBLIC network of radiology stations in the USA? In Canada it exists, and these stations show very interesting data when supercells pass over them...
I'm not a scientist or anything (working for that degree slowly) but these animations make me wonder if the strength of the forward flank winds or the winds coming from the cold pool have any effect on top-down versus bottom-up formation. It seems from the animations that stronger forward flank winds being warmer and being overall less dense cause the particles to quickly rise as they tighten around the updraft and funnel down, where the cold pool particles stay more surface based and rise up. I know this is done with the assumption of a tornado producing EF-5 winds and is in progress, but it makes me wonder if storms where the cold pool is more dominant from rain cooling or encountering any features in the area around it would be more likely to form initially as vortices at the surface before the main funnel appears and vice-versa. It's probably something simple that meteorologists have figured out by now, but i do like asking questions I don't know even if the answer is negligable. Negligable is still a workable varaible.
For sure the density of the cold pool (or, the "coldness" of it) plays a huge role in all mesoscale convective phenomena! If the cold pool is too cold, it tends to rush ahead of the updraft and "gust out". If it's not cold enough, you may not be able generate enough horizontal vorticity in the cold pool. But really it's chaos and there likely won't be neat tidy answers to "the tornado problem"
Posted this on a collaboration video with you and hank too.

My father is a chemical engineer, I got his analytical mind but not his level of intelligence. The following are thoughts/key points from our discussion. Consider them just possibilities.
1) the correlation of pressure dropping, the cold air being utilized more than once thought and the vacuum created by the pressure drop may be a precursor. Think of all that water vapor suddenly becoming rain drops and the space the water vapor originally took up as a gas, being suddenly left open. That might create your vaccum to turn that horizontal rotation vertical to create that upside down U. Lightening is correlated to rain and such, so its interesting that lightening is often intense around a powerful supercell or storm. So, the intensity of the lightening could signify the intensity of those water particles rapidly consolidating into water droplets, possibly forming the updraft of suction of that rotation skyward. Only problem with this theory is that some tornadoes have minimal rain associated with them, so that throws a wrench in there.
2) I have discussed the idea of the cold air in relation to an engine in another video but I'll summarize it again here with some thoughts added in. Life on this planet revolves around oxygen. Plants create it, we and the beasts breath it, fire needs it and even engines need it. Diesel engines run on pressure and LOVE cold air. Compress cold air and diesel in 6 inline cylinders in the right way and you'll push out serious horsepower as you add more fuel and cool air. Hot air works...yeah, but they LOVE cool air because it is more oxygen rich in nature. Particles are moving slower so you can get more oxygen in there. When we breathe, cool air (not freezing but cool) does better than hot air for us. What if a storm was no different? What if they defied their own laws of buoyancy because they feed on the cold air and oxygen? Obviously the temperature difference and wind shear play a roll in storm development...but what if it REALLY wanted the cold air?
These are just thoughts and maybe they are way off. But I think it will take more than meteorologists to figure this out. We need to research the properties of air (oxygen) more in relation to pressure and temperature. What does it do and how does it move in certain conditions? Maybe we are focused on the wrong areas because we spent years trying to prove theories rather than to find the truth. Scientific process cannot be used to PROVE something or else we will try in every way to MAKE IT HAPPEN that way. We are trying to validate things rather than discover. This collaboration between those on the ground and those with the tech is paramount to the field of study. We have to match what is thought to be discovered with reality before we move on to the next step. Otherwise, we are speeding down a road hypothesized to be smooth and straight when it might have a cliff ahead. We need to involve more people that may have been left out before. Chemical engineers, biologists, chemists, chasers, meteorologists, astronomers....anyone could have a theory to test as they have a different angle of approach and are unhindered by preconceived notions (mostly).
Where we are now, we warn at every sign of rotation, so we have nothing to lose by studying new theories and observing. Maybe take that model and tell it what to do. I know you want it to do it alone, but introduce factors you think would kill that tornado development and see what happens. Maybe by searching for what hinders them, we will discover what causes them. Take a bad tornadic events data and change one thing at a time little by little; humidity, temps, dew point, wind speeds.....see if you can mess the storm up and discover what it needs the most to thrive.
Sorry for the long comment, but maybe someone will see it and do something with it. Maybe these things have already been done...
I agree with much of what you commented on especially bringing more professional fields into the discussion for outside points of view hopefully fueling ideas outside the norm so we can better predict these killers. My thoughts exactly when you mentioned more focus on low pressure& cold air involvement. Nice to see others thinking outside the box but critically. May GOD bless!
..... Leigh, I kind of want to play with your computer..... A lot.
dr. orf have you ever tried to recreate the jarrel texas tornado in you model that was one very interesting tornado
thks ken
A truly fascinating storm. I have not tried to recreate this one... nor Plainfield, IL, also of interest. The further back in time you go, the lousier the data you can get, and the details really matter, so you end up mucking around to try to get a reasonable result. So these are probalby not going to happen, or, I'll focus on more recent storms where I can get much better data.
cold air is more dense perhaps thats why cold core tornadoes form and grows quicker?
Wow! 😳
Dumb question time! I appreciate the veiws from SE, NW, etc but I can't quite understand where the winds are the most violent apart from immediately in the path and behind it. We see destruction adjacent to the paths of tornadoes. For example, if a tornado is traveling west to east, it seems that SE and then SW is more precarious than NE and NW to some degree. Would this be somewhat accurate?
Heidelberg -Phil Campbell tornado?
Do you think a watered-down and better optimized version of this sort of software could be used to create a realistic real-time simulation for desktop computers? I'd love to be able to play around with a 3d weather simulation in a sandbox game form. It's honestly my dream game.
There is no substitution for resolution. You could only make a 'toy model' at that level.
@@LeighOrfsThunderstormResearch Honestly, anything that even looks somewhat real would work. A game in which you get to change atmospheric parameters and/or add disturbances in the atmosphere and get to watch it do its thing would be so interesting to me. Maybe someday. I suppose for now I'll just have to stick to watching these videos. They're fascinating.
Which is the front and back of the storm and what direction is the storm headed?
the rfd fuels the tornado so only makes sense why the ef5 eventually becomes rain wrapped
Look at it simulating that powerful RFD! Would this work for any sounding that was launched during the storm even though it was not a tornado. Though you probably would never do that due to the amount of money it takes to run these super computer simulations.
How am I make a supercell out of a giant pond mist maker and some PVC and some pc fans?
That PVC concoction is as crazy as the University of Akron team who claims that fighter craft sonic booms can mitigate or even defeat hurricane systems that build over spans of entire ocean basins. Laughable.

How do you do this
gorg
*_sounds like bill wurtz_*
Tornadoes form in the sea and land
brady pioquid no shit Einstein
Technically called a waterspout not a tornado.
If it forms from a cloud over the ocean it is still a tornado
Waterspouts are water dust devils
@@hughmungus2946 lol u dum
particles = spagetti
Nature is VERY messy!
So input the variables that create a Tornado from a Supercell into AI Programs to better predict Supercells that may become a Tornado.
I know that bro
uhhhh what
So interesting.. we still haven't figured out what really causes a tornado.. we know the parameters that are favorable for tornado formation but we haven't got the big picture yet
Yes, and this is what makes this an active area of research. We all want to find a way to predict, with skill, an hour or two in advance. We have a ways to go. It will likely always be a game of probability, not laser-sharp determinism.

Please never say spawned a tornado you sound uneducated in research.
