A glance at the topographical map of missouri and a map of historical tornado activity indicates that the Ozarks provide a substantial degree of protection from tornados to a portion of the state of Missouri
It shouldn't be impossible to mimic this ozark effect by creating large walls on the west
and south sides of a city with a dense population. A 300-meter high wall should provide noticeable protection.
If the project is done in pure concrete with a base as wide as it is high, a 1km section of wall will cost 4.5 billion, but hopefully, it shall be possible to use cheaper fill materials to bring the cost down.
At this point however, I must admit the cost of such a wall is worth more than the property it could concievably protect-- for now.

The Ozarks may be offering a "rain shadow" effect. The prevailing winds come up from the south or southwest, humid because of originating over the Gulf of Mexico, so it would rain more on that side of the Ozarks, and northerly of them there would be less humidity in the air. Not as much-less as the rain shadow of the Rockies, because the Ozarks aren't as high. |
|
|
The Ozarks are also modest in extent, so humid air can go around them. But near to them, where the rain shadow happens, that would be the place somewhat shielded from tornadoes. |
|
|
In the plains to the north of the Ozarks, it is the condensation of humidity into rain, when a warm-humid weather front meets a cold front, that provides the energy that drives tornado storms. |
|
|
Such a wall with a gently sloping outer face built circumferentially around a city would make incoming tornadoes catch air and jump cleanly over the city. |
|

Talk about an urban growth boundary... |

Fascinating tornado facts: ~A tornadoes' direction of spin is influenced by which hemisphere it is in. Northern tornadoes usually spin ccounter-clockwise. ~North American natives told settlers that tornadoes never strike at the joining of two rivers. ~Lots of cities have been hit by a tornado but never a downtown core with large buildings. ~I've watched one form overhead and touch down about a kilometer away... It was awesome! |

hmmm I wonder if anyone has figured out how to use HAARP to make directed tornadoes and hurricanes yet? If not yet, they will. |
|
|
A wall that large could certainly house a tornado, if it wasn't filled. Instead of a wall make it a trap and lure tornadoes inside using a trail of old trailers. Once it is inside, shut the door. |
|
|
Ha - a wall to prevent tornadoes... How about abandoning the stupid SUVs and other gas guzzlers that have caused global warming, which is the reason why these monster storms will only continue to increase in ferocity? Try building a wall around New York City to stop it from being inundated by the sea. Good luck with that. |

" If the project is done in pure concrete with a base as wide as it is high, a 1km section of wall will cost 4.5 billion, but hopefully, it shall be possible to use cheaper fill materials to bring the cost down." |
|

It sounds like an arcology project. While pure concrete (99.999 fine?) is pricey, there are plenty of crushed trailers and automobiles to use as fill. |
|
|
You could also honeycomb the structure and sell living and commercial space in the cells. |

Good point. There have only been tornadoes in the
last few decades. |

That is utter and complete nonsense on every
level. About the only thing that actually is
happening is population growth, particularly in the
West and South and of course at the shores,
which is putting more people in
harm's way. But just a wee bit of googling will
show you that we've had multiple periods of
waxing and waning tornado activities, ditto of
course for hurricanes and the like. |
|
|
And only a complete and utter lack of thought
clarity-- truly -- would blame SUVs -- a mode of
transportation that has existed in any meaningful
numbers for less than 30 years -- for climate
change. |
|
|
Google itself, and the rest of the Internet is a
likelier culprit then -- just do the math on data
center power consumption since the 80s. |
|
|
We're not running out of oil, of food, of water, or
of climate, and the rest of the planet owes us
pretty much everything in advance for that asteroid
we're going to steer out of the way some
day. So turn on the polluting AC if needed, and
chill. |
|
|
A cursory Google suggests that the supercell
formations responsible for tornados are formed
when the moist gulf air hits dry prairie air. Now, if
the differences can, to some extent, be ablated,
then you should be able to mitigate the problem. |
|
|
So, flood as much of the midwest as possible.
Admittedly, there's not much rainfall, and it's a bit
high to expect much inflow. But a few lakes and
canals here and there, preferably surrounded by
Forrest should buffer the situation a bit. |
|
|
The extra biodiversity will do no harm either. |

Not if several billion Chinese and Russian astronaut
miners have chipped it away first. |

Just don't mention Osaka airport, or whatever the old Yokohama dreamland project was, built on old landfill site. They don't always get it spot on. |

[MB], I meant us humans, not us Americans. |
|
|
There's an upward trend in tornado sightings since 1950, so I suppose it's fair to suspect global warming does have a role. |
|
|
However, there are regions of the US where even the 1950's rate of tornado formation is not a good thing. |
|
|
That said, if you generalize "abandon gas guzzlers" to "use energy more efficiently" it's hard to object. |
|
|
It is my hope we can enhance human quality of life as we reduce energy use-- safer cities that require less maintenence/repair, shorter commutes(thus less gas needed for daily life), lower HVAC bills etc. |
|
|
The key word there is "sightings". More people, more
radar. More reports. |
|
|
yes, in the 50s, those cell phone videos of tornadoes
were few and far between. |
|
|
For energy to be "used more efficiently", you really
need only one thing -- price it according to market
conditions. The money savings are sufficient
inventive in it of themselves |
|
|
Instead of a wall, install apartment buildings that are miles long with very small windows facing the tornado winds. That way the towns you are trying to protect could double in size. |
|
|
"Hello! Where is apartment # 30,667?" |
|
|
First, a month after the tornado wall was built,
you'll discover that all wildlife breaks down,
because the animals cant get to their water
sources. When rats and snakes start entering the
towns in large numbers, and there are major fish-
death events reported in the contaminated lakes
and rivers, it will begin reaching the headlines,
and people will start wondering if it has anything
to do with the large walls. |
|
|
Then you'll discover that the wall stops all winds
and breezes and causes warming to
unprecedented temperatures, which in turn bring
a dry-out of trees, followed by creating snow
conditions for extra cold winters, and finally
evaporating the fossil water through cracks in the
ground caused by all this wear and tear allow the
lava to break through and voila - you have a
volcanic eruption. |
|
|
But the tornado won't pass. |
|
|
By the way, in my country they tried such a wall.
Against terrorism. Many, mistakenly, still think it
was a good
idea. |

|

Would the sightings have gone up by about two-and-
a-half fold? Only I'm thinking that sightings of just
about everything should have gone up by about two-
and-a-half fold, there being about two-and-a-half
times more people around now than in 1950. |
