pressure.
The air pressure inside a tornado is very low.
low
No one really know pressure can vary for the type or category of a tornado.
Yes. A tornado is pretty much made of air. Although pressure inside a tornado is low it is nowhere near being a complete vacuum.
The air pressure inside the funnel cloud of a tornado is extremely low. The pressure can be significantly lower than the surrounding air, which contributes to the destructive nature of tornadoes as it can cause buildings to implode and objects to be lifted and thrown.
Yes, the eye of a tornado typically contains air from the surrounding environment, which includes oxygen. The winds inside the tornado can be less turbulent in the eye, allowing for the presence of oxygen in that part of the storm.
The air inside a tornado is cooler than its surroundings. This is not due to the wind or the fact that it comes from the sky, but from the fact that the pressure in a tornado is low. As air enters a tornado it is decompressed rapidly, and cools as a consequence. This is predicted by gas laws. In many cases the temperature inside a tornado is less than the dew point, which is why the funnel forms.
This is a fact. The low pressure associated with a tornado can cause buildings to explode as the tornado passes overhead. The rapid change in pressure inside and outside a building can create a force that can lead to structural failure and cause the building to explode.
The low pressure inside a tornado draws air inward, accelerating it to great speeds. Once air is in the circulation the low pressure at the center keeps it on a somewhat circular path.
The pressure inside a tornado funnel is lower than the pressure outside. This pressure difference is a key factor in the formation and strength of tornadoes, as the low pressure inside the funnel contributes to the destructive force of the winds associated with tornadoes.
Tornadoes have low air pressure at their center, known as the "eye" of the tornado. This sudden drop in air pressure can contribute to the destructive forces of a tornado by causing buildings to implode and trees to snap.
There is no required pressure at which a tornado forms. Large scale low pressure systems play a role in tornado formation, but the low pressure is not a direct cause of tornadoes. On rare occasions, tornadoes can form with air mass thunderstorms that occur in the absence of a large-scale weather system. There is low pressure inside a tornado, but in this case the important part is not how low the pressure inside the tornado is, but how much lower the pressure is outside the tornado. The range of these pressure deficits is not known as very few measurements have been taken.
