What happens to the barometric pressure during a tornado?

Answer 1

Tornadoes are caused by winds.

When a tornado forms the wind pressure around the tornado drops and that's what you see on the barometer, the pressure goes down.

Answer 2

We have a lot of tornadoes around here (I live in the area that's been hit so hard over the last six weeks, though fortunately my exact location--barn, house, etc.-- has been spared...). My horse is boarded, and he's only turned out for a few hours a day anyway, and he stays inside. There are some horses that stay outside, just because that's where they're always kept and there's nowhere else to put them. I read an article about a recent tornado that destroyed a farm somewhere (can't remember) and the horses that were outside were killed. Yes, a tornado is strong enough to do pretty much anything. If the barn is really sturdy, it has a better chance of surviving the tornado (and protecting the horse) than a lone horse in the field does. When it comes down to it, though, tornadoes are unpredictable and there really is no "safe place"--if the tornado hits directly, it's going to destroy everything in its path. If you do have severe weather headed your way, put your phone number on your horse somehow (braid it into the mane, spray paint it onto the horse with horse-safe spray, write it on the halter, etc.) so that if the horse goes missing (ie, the fence is broken and the horse gets out, or the tornado literally takes the horse but the horse survives) you'll have a better chance of finding it.

Answer 3

Tornado Air Pressure

Answer 4

When a tornado forms the wind pressure around the tornado drops and that s what you see on the barometer, the pressure goes down.

Answer 5

The cause of the drop in air pressure has to do with hot and cold air masses. As cold air pushes into an area of warm air, the cold air is more dense and sends the warm air aloft. When this happens, the moisture in the warm air condenses, causing heavy rains. Howevever, the spin of the earth's jet stream puts a spin on the air aloft. This causes tornadoes. The ground air pressure is so low, that the tornado is trying to balance the pressure by sucking up air at ground level to the high pressure sustem.

Answer 6

Yes, it drops very low. This is the reason windows and doors are blown out of houses, etc. If a tornado is coming towards your house, open all the windows and doors and then head for the basement or shelter. It might help save some of your house.

Answer 7

Pressure drops incredibly low. it can drop as low as 750 mb in the strongest tornadoes.

Answer 8

It drops.
