      Bombing a tornado will only work if it is also a tornado full of sharks. One might even call it… a sharknado.

      But not government bombs, they have to be improvised like you would in a video game and not a terrorist because that is cooler. And dropped from a helicopter, but not just any copter, it has to be commandeered, but in a legit way because we have to or no one else will.

      Bombs are for insecure politicians, idiots and religious extremists. Furthermore, bombs are the French cowards way to fight weather events. Any American worth their powder knows bullets are the only way to stop tornados. Shoot them fuckers full of holes and leave 'em laying in the fields so their buddies know what's coming to them if they don't turn back.

      In all seriousness, it sounds like the fella that published this may not have actually seen much in the way of post tornado footage before the EPA began targeting the poor with the automotive tire disposal fee scheme that went into effect in the late 1990's.

      The way things work now, when you buy new tires there is a fee ($4.00 per tire I believe) for disposing of the old tires. Most places charge you the fee even if you want to keep your old tires, so people tend to let them take the old tires so they don't feel like the tire place is getting $16 for nothng. But before the tire fee it was common for people, especially the poor, to keep their old tires, in case they ever needed them again. The EPA knew this, and they knew what the old tires really provided, thus the old tires had to go if they wanted to succeed in ridding the country of the poor.

      The EPA knew that old tires provided tornado protection to people who live in the mobile home communities (trailer parks). Think I'm bullshitting? Go look at pre-1997 aerial footage of tornado stricken trailer parks. The only ones left on their wheels always have at least one old tire on the roof. ALWAYS! Nobody really knows how the poor people worked out that putting a old tire on the roof of their trailer provided tornado protection. The calculations were assumed to be beyond the means of the poor. It doesn't really matter anyway. Now that the EPA has effectively put tornado invincibility beyond the means of the poor by eliminating used tires the poor are expected to eventually disappear as their habitats are destroyed.

    But how long? Building a wall the same height as the comcast tower may be simple if it is also the same width as the comcast tower, start building a wall multiple miles long and I'm sure complexities start to happen (roads, wildlife and existing buildings for a start).

    The maths on a "mere" $160 million per mill also don't stack up particularly well, just 10 miles is 1.6 billion, three 33.3 mile stretches are 16 billion, (see comparison to costs of tornadoes here http://www.spc.noaa.gov/faq/tornado/damage$.htm).

    Perhaps if they built more houses out of bricks not sticks then the hurricanes wouldn't blow them all down? This is likely to be far far cheaper and have many health and other positive benefits to the poor in those areas as well!

      No bricks will survive category 5

      No bricks will survive above category 3 tornado.

      The only thing that may stand a chance is something half-dug into the ground, with nice aerodynamic shape and some tank grade armour plating to go over all doors and windows when things get ugly. Effectively "a nuclear shelter of a house". This will cost ~4-5 times more than current construction sans the armour cover for the windows and doors (just the dug-in concrete shell). With the windows and doors you are looking at 10x times or more. I do not see anyone starting to build any of these any time soon.

        He wants to construct walls not buildings nor houses.

        But even a wall would be too tiny. And why just a wall ?

        The cheapest thing to do would be creating giant artificial mountains. That's it. Giving those a structure similar to existing mountains, using hard rocks and metals.

        Mountains don't get crushed by tornadoes. Constructing artificial giant mountains even harder than the existing natural ones wouldn't be as expensive as constructing long tiny walls with a given shape.

        A mountain can have bad shapes but as long as its density it's very high it would do the job perfectly against any tornadoes and wouldn't break down. Only a volcano appearing and erupting where such artificial mountains would be built could then cause such huge things to get destroyed.

              The wall will not survive a tornado, but it's not supposed to is it? I thought the point was that having walls in the right places will prevent the tornado from starting in the first place? As for bricks, I doubt they'd use bricks for the wall, they'd use concrete, like a dam. Bricks only came into the discussion because someone above said about building houses with bricks instead of sticks. Do try to keep up old chum.

    According to other boffins, won't work

    I saw the response to this from other scientists who actually study meteorology and climate. For some reason, the low mountains in the exact area these walls are proposed aren't doing anything to even slow down the formation of tornadoes.

    However, if it were proposed to build a sculpture the same size, I bet it could get funding.

    1. Joerg

      Re: According to other boffins, won't work

      Those so called scientists are telling lies then. Because in other countries where there are huge mountains there are no tornadoes like there in the US. Those mountains surely do "their job" tornadoes wise.

      1. Preston Munchensonton

        Re: According to other boffins, won't work

        What other weather impact would these mountains have? It's easy enough for a physicist to blindly suggest an artificial mountain, but it's another thing entirely to introduce a climate-changing monstrosity that will undoubtedly have other effects. Those other effects need study before just making such a suggestion.

        1. Grikath

          Re: According to other boffins, won't work, other effects.

          Well for one, you would get a rather serious change in local precipitation since , if effective, the walls will prevent the mixing of the air masses altogether with rather profound results. And very likely: very profound results that will disrupt and damage the local environment more than the tornadoes cruising through at the moment.

          I'd love to see a precipitation model based on blockage like that. I bet a beer there will be some more dustbowls in sight soon.

      2. Don Jefe

        Re: According to other boffins, won't work

        The mountains here in the US are pretty fucking big man. So are the Great Plains where this guy wants to build walls. The Plains cover about 1,300,000km2 which is more than large enough for massive weather systems to develop and play out especially considering it's all low altitude land that's as flat as a tabletop.

        Although it is very interesting, and the backstory has just got to be fucking fantastic, mixing xenophobia and geography is not a well understood science. There no evidence to suggest that mountains express a labor preference based on either location or culture. As we currently understand them, mountains express very little in the way of emotion or bias and seem generally satisfied with their surroundings once they've established themselves. If they are unsatisfied they have failed to communicate that or moved away in search of fulfillment. You can't help those who won't help themselves.

        The more well understood science part behind your observation is rather simple. None of the other places with big mountains have those mountains bordered by several thousand miles of ocean on one side and thousands of miles of low elevation flatland on the other. The sheer scale of North America, combined with its geography creates a really weird situation that's unique to this planet.

        Keep working with Xenophobic Geography though. There's a lot of potential there I believe. If you can really get it all laid out well I bet there's a way you can sue the States that have big mountains and claim emotional distress caused via excommunicative bias.

          "The sheer scale of North America, combined with its geography creates a really weird situation that's unique to this planet."

          I've heard of US exceptionalism but that's taking it to extremes isn't it?

          On a serious note, I find it somewhat hard to believe that creating what is essentially an artificial windbreak will not have some repercussions beyond the desired "stop tornadoes".

          Climate is a complex thing and difficult to predict. You can see that by how skeptical many are about global warming as they tie it up with climate change. An increase in heat energy trapped by the earth's atmosphere is an input into the climate system - the confusion is around how exactly that will manifest so far as climate changes go.

          Given the rather stark contrast between one side of the Andes (the Atacama) and the other (the Amazon), it's pretty evident that the blocking and diversion of winds (which carry moisture) can have some pretty big effect.

          The proposed walls are nowhere near the scale of the Andes but to think they wouldn't have a noticeable effect all the same is a bit optimistic, I'd say!

          1. Don Jefe

            Re: According to other boffins, won't work

            I'm sure some mini mountains would fuck up weather patterns. The big man made lakes here drastically altered the weather within my lifetime. Make something big enough and of course it'll have an impact on weather.

            I fail to see what that has to do with the unique geography of North America however. There are precisely zero other places with geography remotely close to that of North America and there sure as fuck isn't a vaguely close second in South America. That's not 'American Exceptionalism' talking, that's literacy and experience.

            There's very little big geography between the Andes and the Atlantic Ocean. Certainly not a second set of mountains to trap all the weather. To the west of the Andes you've got the driest place on Earth. Australia is the closest, but it's not really comparable. If you look closely, you'll see that Australia is surrounded by water and has what is effectively the worlds largest wind machine to the south. There is no corollary here.

            'American Exceptionalism' is stupid and it's embarrassing. But you're foolish if you think there aren't some unique features here. The entire continent is chock full of geographic oddities and the result is, among other things, really weird weather. It doesn't make this part of the world better, or anything of the sort, but it does make it unique.

    We need a bigger shovel

    One kilometre linear of these 'mountains' would need 15 cubic kilometres of material to construct, that means either a large hole somewhere or a smaller mountain. Tens of kilometres long walls will mean much bigger holes or much smaller mountains and quite a lot of trucks and fuel to move all that material, it may be doable but it may also be be ecologically and economically more beneficial in the long run to not bother.

      Would you like to have another look at the back of your envelope? Even if the wall is 1km high (it's only 0.3km high) and 1km wide (it's only 0.05km wide), each 1km length would require exactly 1 cubic km of material, assuming it has solid construction. It's impossible to cram 15 times that amount into a much smaller structure!

      My envelope says that for each 1km of wall which is 300m high and 50m wide and has a void inside* (50% of cross-section) we'd need 0.0075 cubic km of material.

        Re: We need a bigger shovel

        @Martin

        Dirt doesn't work like that. You'd end up with a big speed bump, not a small mountain. It's not a perfect analogy, but you can think of dirt like those S-shaped packing peanuts but made of hydroscopic material that's reasonably dense.

        Unlike packing peanuts that are engineered to occupy as much space as possible, dirt wants to be packed in tightly with other dirt. Left alone, dirt will compact itself to a surprising degree. Its hydroscopic nature works as sort of a pump where the wet dirt expands then contracts as evaporation and gravity remove the water. As it contracts gravity pushes the individual bits into the voids that appear, effectively at random.

        That's a big part of the reason you don't see dirt hauled by rail very often and why dump trucks for hauling dirt are limited in size. A regular big dump truck holds about 3 cubic yards of dirt but if you haul it a long way or encounter serious rain on the trip you can pretty quickly end up with a 1 cubic yard brick that's stuck in the bed.

        That's a very simple mechanical compression technique that's still randomized. If you get serious with it and start refining the soil and shaping it for maximum density you can exceed 20x compression without getting too exotic. Whether or not it's financially effective to process enough soil to build small mountains with is another story, but there's no doubt it'll take several times more dirt than is necessary form the shape to actually build them if you want them to stay that size.

    Stop

    Neat!

    Tornados trapped against mountains are neat! Even when the actual tornado breaks down the weather system that spawned it tends to get stuck by the mountain and hangs out for a while, just kicking the living shit out of everything. If your lucky it'll just be a single storm and blow itself out in a few hours. It's actually fun in an awe inspiring way. But sometimes several small storms all just pile up on top of each other and it's some incredibly powerful angry planet shit. All the energy is still there, trapped, and it goes on for hours and hours and hours. The next morning there's not a god damn bird, squirrel or whistle pig to be found anywhere. They've all been blown away, crushed, struck by lightning or drowned.

    People don't hear about it much, because there are no visuals. It almost always happens at night as the temperature differentials between the high mountain air and foothills collide and the power always goes out. Plus it's mostly just poor Southerners so nobody really gives a shit anyway. The entire border between Tennessee and North Carolina (that's where I'm from) is subject to some of the most consistently violent, dangerous and damaging weather in all of the US.

    The tornados are effectively stopped by mountains, in exchange for a straight line wind generator that does all the damage of a tornado and drives rain in unbelievably destructive ways that can't coexist with a tornado. Before building some new mountains I think our 'tornado wall' idea guy ought to go spend a few summers in the mountains down South. It may not seem like such a great tradeoff when everybody in the flat States, and all the corn for next years booze, is drowned. Because that's exactly what's going to happen if you build an enormous rain machine in a big bowl that isn't built on karst and doesn't have thousands of miles of streams and rivers like the South does to deal with the runoff.

    Might I suggest a better way?

    If mixing of two massive amounts of hot/cold air is the problem, then why not build big air ducts with pumping stations at appropriate locations? Obviously we can't expect to be able to mix huge weather fronts, but we might be able to "pre-mix" enough of it so that the larger twisters simply don't have a chance to develop.

    As it is, if the solution is to build a wall, then surely it's just moving the problem somewhere else? Unless you build it long enough that the warm fronts will have dissipated by the time they get around, I guess...

    Also, wasn't there a Russian who thought you could stop hurricanes by flying around them backwards?

      Finding the material shouldn't be all that difficult... all you need to do is set off the super volcano under Yellowstone, that'll probably chuck up plenty of rock and stuff for building mountains!

    Nature will find a way

    If I recall my Jurassic Park right: "Nature will find a way". Same thing here. Predicting nature is about as easy as herding cats - you should try it some time - hours of mind numbing fun!

    Set up those walls and you'll just create all new weather patterns on both sides and permanently affect the weather patterns across the rest of the good ol' US of A. All those New York Winters with 3foot high snow falls could be 3 inches or 30 foot deep instead. Sunny and dry California is the new Bayou.... take your pick...

    And as for the walls; the earthworks alone for the foundations would boggle the mind!

    Just give everyone who lives in Tornado Alley an old truck tyre and a set of instructions - "On sighting an incoming twister, Grasp tyre firmly; Shout "Go away nasty Tornado!!"; Throw tyre at tornado." It would probably do a better job than the walls.

    I've a team of paddy brickies standing by for the build! £50 for the total job, O.K.?

      I t'ought you said you wanted TREE FELLERS for a big job, Mick an' Dara an me, see, we're arborists, not bloody brickies!

    a cheaper alternative

    Given the direct connection between tornadoes and Southern beauty queens (sooner or later they both end up in trailer parks), just tear down all the trailer parks.

    Voila! No more tornadoes!

    Scaffolding

    Hmmm - wall 300m high by 50m wide by some-unspecified-km length. That's a lot of scaffolding. Better get in some more bamboo...

    Gosh durn turnado...

    Gunna build me a big ol' wall, keep them pesky durn turnados outta my back yard. Git! gwaan outtahere! Pesky durn turnado. <mumble, grimble>

    Might as well build a 1000ft wall around all the red states and while we're at it might as well fill it with water.

    It's really too bad that they'd need more than one mile of wall...

    "...one mile of wall would cost a mere $160m – chickenfeed..."

    Presumably 1000 miles of wall would cost $160 BEEEEEELLLLEEEEEON. Another Moon shot.

    I think that the Chinese have some experience in this area...

    That'll work.

    I think it was Frank Herbert that wrote in the Dune series of books what a mess could occur when Humans attempted to "Fix" climate, in short it resulted in complete disaster. Now I know Fictional Books aren't exactly scientific fact but we all know Sci-Fi is our window to the future, mostly.

    Anyhow, Without any scientific basis what so ever, if any species of a planet tried to start to alter climate to suite "their" needs it stands to reason someone else will end up paying for it, even now it doesn't matter what we have done to improve something, somewhere else gets hit, sea defences, beach defences, river flood protection, all wonderful for the folk that get them, for everyone further up the beach or down stream, tuff luck, I cant help wonder if this is just another one of those things where the people who can, will, everyone else needs to suck it up.

    I extend that argument to global climate change as well, at what point does global warming cease to be natural and at what point to we allow sea levels to rise as would naturally happen.... but that's another debate for another day.

    Large volumes of air act like liquids. You can produce a water "tornado" anytime you want - just drain the bathtub and watch the drain. If they really want to test this idea, construct a model in a water tank. The water will find a way either around or over the barriers. This may cause unexpected consequences when entirely new weather systems form because of the barriers. Messing with a chaotic system like global air currents should be attempted VERY carefully. Oklahoma has been plagued with earthquakes since fracking began there. It turns out that messing with a chaotic geological system should also be attempted very carefully. And there is no telling if the damage to the Oklahoma geology can be reversed or fixed. Remember that before you go playing with global air currents.

    Thousand Foot Walls?? Sure, Why Not...

    Hills in Tornado Country seem never to get hit...no matter which way they run...similar problems in the High Country desert of Colorado= winter storm damage is minimised by building houses under the south sides of high desert canyons...can't plant trees as no excess water...

    Q= Where is the building material coming from??

    Possible Solution= Think Ocean Waves on the great planes constructed On - Site by simply digging 2 ditches on each side of the proposed 1Kf wall... if the contoured ditches were 300 ft deep, the removed material would easily construct a 700 ft mound that added to the adjoining ditches= 1Kf wall...done. We build earthen dams everywhere n they seem to be durable... nothing says they need to be either continuous or arrow straight... think excellent new park n Recreation areas...topped w/wind generators, they could be financed like those hydro dams in the NW...bury the power transmission lines...done...

    Note= the Black Hills in the Dakotas already look like this n they never get Tornados...RS.
