    Great walls could eliminate major tornado threat in Tornado Alley, expert says -- ScienceDaily

    Is this the craziest idea yet? Or is it great vision?

    The suggestion is that Tornedo Alley can be so modified by 3 great east/west walls as to stop all the worst tornedos and save both human life and billions of dollars of destruction.

      three lines of 100 story buildings for how many hundreds/thousands of miles? seems perfectly practical... Does the earth even have that much raw material?


      "Should any political party attempt to abolish social security, unemployment insurance and eliminate labor laws and farm programs, you would not hear of that party again in our political history. There is a tiny splinter group, of course, that believes that you can do these things. Among them are a few Texas oil millionaires, and an occasional politician or businessman from other areas. Their number is negligible and they are stupid."

      Tornados occur in many places not just tornado ally. Look at the last ones that struck Nebraska and other northern states.

      Weather science. can it be proposed that great walls might alter wind flow patterns to eliminate the tornado risk. Then building of conventions known is not a really a possible ability. Simply put, Yes. Far too much material would be required for such as walls of substance. Large reflective surfaces placed in orbit to reflect solar heat to altar weather risks.. Weather science could be what we need to invest in.
      Or just investigate in.. Like a curtain of warm air to inhabit a Thunder Cell forming.. I would think we could do these things.. if the want was for it.

      If they were about 10 miles high that might work-- most tornado's start in the mesocyclone that forms well above the ground.

      I can't find the author or the study, nor is it published in a meteorology journal.

      The article also badly explains why China gets fewer tornadoes compared to the US-- and their reporting is rather sketchy particularly for non lethal events. The "zone of mixing" is piss poor explanation of why the US thunderstorm complexes are so potent--it's missing the important parts of Gulf Coast moisture being carried on low level jets and the effects of the elevated US Western plains to storm genesis.

      Tornado Ally includes the Northern Plains.

      There was a generation scheme proposed for Australia, essentially a giant chimney that would anchor and accentuate a dust devil. So perhaps for N.American tornadoes rather than fight them we could work with them? Think of this as untapped energy searching for an excuse to flow.

      I don't think that was quite how it worked. The solar chimney idea was a means of generating electricity from the sun. It involved a glass house of rather large dimensions to heat air, which was channelled into a tall chimney, up to 1 km high. The air rising in the chimney would accelerate up and turn a turbine.

      Dust devils were not involved.

      I suspect that radicle changes to the building codes in the affected areas might be considerably cheaper.

      It's essentially the same thing. In both cases hot (sun-heated) surface air vents upward in a tight column, or "chimney". In future - as we do with hydroelectric "waterfalls" - we'll regulate a natural phenomenon and tap the energy with turbines. Anyway, my point is why wall-out a natural flow when we can fix it in place and exploit it.

      That is like suggesting we use lightning for power generation. Sounds good in theory, but no one has the faintest idea of how you would even begin to harness something so chaotic.

      ~ Can I ask that these ideas ( i do not have many ) be looked at and considered as serious.. suggestions of weather manipulations..
      We could even save lives.. or make it rain where it would not normally.. I can see we have this ability do we have the want ?

      This one can't be taken seriously because it shows a complete lack of understanding of how tornadoes form or the storms that produce them.....for example most tornado producing supercells aren't even associated with surface fronts.

      Most such proposals fail for similar reasons or for lack of understanding the incredible amounts of energy involved in violent storms.

      Public education, awareness of warning systems, good forecast, weather monitoring (by public and trained professional), and laws that require good structures and shelters are far for effective at preventing deaths that half-baked ideas to stop the storms.

      ~~~ But I saw it on U-Tube... Oh well, that's the end of that moment in the light.. are you so sure we....
      Then I must agree.. educate the populous to build better or in safer locations.. We need to adapt.

      Chaotic lightning, we regulate with lightning rods. You're right: it's similar because nature creates a potential (i.e. hot surface air that would move to higher altitude/lower pressure) and we encourage the discharge along paths we provide. Without artificial paths, there's no telling where dust devils might strike.
