What is the middle of a tornado?
There's nothing, its clear and calm
On damage A rating of a tornado on the Fujita scale is determined by the severity of the damage the tornado does. It can only be determined after the storm has ended. For example, if a tornado appears in the middle of an open field that stretches for miles without civilization and dies before it can destroy anything, it is considered an F0. If a small tornado appears in a town and destroys well-built structures…
The appears to be asking about multiple vortex tornadoes. The process of how a tornado becomes multiple vortex is called vortex breakdown. Thi occurs when the wind in a tornado is spinning so fast that it cannot reach the center. The low pressure instead draws air down the middle. This causes the tornado to expand. When the downward moving air reaches the ground it spreads out. Complex interactions between this outward moving air and air…
The winds in a tornado are actually fastest at the edge of the funnel. Withing that radius the tornado rotates as if it were a solid object, so wind is not as strong at the center as you might expect. The pressure at the center, however, is quite low. In some tornadoes a downdraft descends though the center in a process called vortex breakdown.
If you are too high to get to the bottom floors, go to an interior hallway or better yet, a stairwell towards the middle of the building. The idea is to put as many walls between you and the tornado as possible. Stay away from windows as the greatest threat in a high rise building in a tornado is flying glass.
No. A tornado produces the steepest pressure gradient of any weather phenomenon. An intense mid-latitude cyclone might have an overall pressure deficit comparable to a weak tornado, but that pressure gradient is spread out over several hundred miles. A tornado produces at least that much of a pressure drop over only a few hundred feet.
