Why does opening windows during a tornado to prevent the house from being lifted off the ground?

It doesn't: that is a myth.
The idea stems from the fact that the pressure inside a tornado is very low and the higher pressure inside a house will cause it to explode unless windows are open to relive pressure.
The truth is that the winds and debris of a tornado are what cause damage, not the pressure difference. Even in a relatively weak tornado that will cause only moderate damage the windows are likely to break anyway. In fact, in the case of a weak tornado or indirect hit that would not break windows, leaving them open allows strong winds to enter the house and cause damage on the inside.
The pressure drop in a tornado is not great enough to cause damage and even then, houses are not airtight, and pressure can equalize on its own fairly quickly. The greatest pressure drops come in the strongest tornadoes, which can easily tear apart a house with their winds regardless of any pressure difference within the structure.

What is the safest corner of the room during a tornado?
There is no safest corner of a room. The best place to be in a tornado is in the center part of a building away from windows.
Why do you need to hide where there are no windows during a tornado?
Windows can break easily even in a weak tornado. The broken glass, which can be carried by the wind at high speed, can pose a serious risk of injury or death. Additionally, since windows are so fragile the offer virtually no protection from debris. While a wall will stop most projectiles, a glass pane will not, and flying debris is the thing most likely to kill you in a tornado.
Why would a closet be safe during a tornado?
A closet is small, and as a result, the walls do a good job of supporting each other. In larger rooms the walls have longer spans where they are not supported by another wall, making them more likely to collapse. Additionally, closets do not have windows, which are dangerous to be near during a tornado.
What would the air pressure be during a tornado?
Pressure inside a tornado is very low.
Is there lightning during a tornado?
There can be, but it is not a requirement for one. Search google for tornado lightning and look through the images to see.
Why should you not open windows when a tornado is approaching?
You shouldn't. Contrary to popular belief opening windows during a tornado does nothing to save a house and may in fact make damage worse. If a tornado is coming opening windows is a waste of precious time that you should use to take cover.
Is it better to open or close your windows during a heatwave?
Windows are best left closed in a tornado. If you are not hit hard, the windows can prevent interior damage. If you are hit hard by a strong enough tornado some windows will break anyway. But if a tornado is coming it is best not to waste time opening or closing windows. Take cover immediately.
Is it a good idea to open your windows during a tornado?
No. Opening windows does nothing to safe your house and can help expose the interior to damaging winds.
Are windows to be closed during tornado?
yes In the case of a weak tornado a closed window can prevent damaging winds form entering the house. Though if a tornado is coming do not waste time with the windows. Take cover immediately.
Why is opening the windows during a tornado a myth?
The openting windows myth is based on the idea that the low pressure inside a tornado causes houses, where pressure remains high, to explode and that opening windows equalizes pressure. This does not work for several reasons: It is wind and debris in a tornado that causes damage, not the pressure difference.The pressure difference created even inside a violent tornado is a fraction of what is needed to cause significant damage.Houses are not airtight, even with the windows closed.A tornado strong enough to cause major damage will create plenty of openings and break the windows anywayIn a weak tornado or a glacing blow, opening windows exposes the interior to strong winds, which can cause damage inside as well as outside.
Why should you stay away from windows during a tornado?
Windows can break even in weak tornado, creating flying shards of glass. Windows also offer no protection from flying debris, which is the greatest danger in a tornado.
Why are people in a building threatened by a tornado told to open their windows to minimize damage?
This is based on the old and now disproven idea that the low pressure inside a tornado caused buildings to explode. The idea holds that as a tornado passes over, the pressure outside drops radily, while pressure remains high inside the building, and that opening windows would relieve this pressure difference. This idea has been disproven, and officials now advise against opening windows during a tornado. There are several reasons for this. First, the pressure drop inside a tornado is not large enough to inflict any significant damage on a stroncutre. Second, buildings are not airtight, and pressure will equalize fairly quickly. If a tornado is strong enough to cause significant damage, the windows will likely break anyway Tornadoes cause damage through wind and debris, not through pressure drop. It has actually been shown that if the tornado is weak enough that windows remain intact, or if the worst of the tornado misses, opening windows allows wind to enter the building and cause damage on the inside. Additionally, opening windows wastes precious time that should be spent getting to a safe place.
Why do windows implode during a tornado?
The winds of a tornado carry a tremendous amount of force. This is often more than enough to break windows. Additionally, some windows may be struck by flying debris.
What should you do if you are in a gymnasium during a tornado?
Get into a hallway or bathroom way from windows. A gymnasium can be a dangerous place during a tornado as the long span roof and tall walls can collapse.
Where is the best place to be if you are in a school during a tornado?
An interior bathroom or hallway away from windows.
What is the safest corner of the room during a tornado?
There is no safest corner of a room. The best place to be in a tornado is in the center part of a building away from windows.
What can you do to stay safe during a tornado warning?
You can go in a place without glass like windows
