(KETK) - Tyler, Tx — We all know that tornadoes can be dangerous and deadly.
But there is a physicist from Temple University who believes that if gigantic walls were built from the Northern Plains all the way down to the Texas and Louisiana border, then this would diminish the tornado threats in tornado alley. USA Today reports that the size of the walls would be about 1,000 feet high and 150 feet wide.
Would this prevent violent tornadoes?
The strength of a tornado is so strong that it will pick up anything that is above ground. Tornadoes have so much wind energy, and the speed of the winds are so impressive that it creates lifting at the surface. This lifting mechanism at the surface is called a meso-low. The meso-low is a localized area of low pressure that helps create vortices and produce tornadoes.
The final answer: No. It nearly impossible to place walls in Tornado Alley and expect them to withstand a violent tornado. The best place to be in a tornado is underground or an enclosed area away from outer walls.
The cost for this project would cost $60 billion dollars per 100 miles of wall.
