The pressure inside a tornado is low compared to its surroundings, though exactly how low pressure can get in a tornado is unknown as few measurements have been taken, but it is generally accepted that the lower the pressure in a tornado, the stronger it is.
Wind in a tornado moves in a circular fashion very rapidly, so the tornado is actually a type of powerful vortex. On rare occasions these winds can exceed 200 or even 300 mph (320 or 480 km/h). In addition winds in a tornado move upward very quickly at speeds similar to those of the rotation.

What else can I help you with?
Does high air pressure increase tornado rotation?
High air pressure aloft can increase wind shear, which is a key factor in tornado rotation. Wind shear is the change in wind direction and speed with height, and when it increases due to high pressure systems, it can enhance the rotational capabilities within a storm system and potentially lead to tornado formation.
Does the wind go toward a tornado?
Yes, the wind typically flows inward toward a tornado in a rotating motion. This rotation creates the characteristic funnel shape of a tornado as the air spirals inward towards the center of low pressure.
Why is debris often described as being sucked in to a tornado?
Debris appears to be "sucked in" to a tornado due to the strong inflow winds leading into the tornado's vortex. The low pressure inside the tornado combined with the high wind speeds can lift and carry debris into the storm. This creates the illusion of objects being pulled into the tornado.
What role does pressure play in a tornado?
All wind on Earth is ultimately driven by pressure differences. As a general rule, the more the pressure changes over a given distance, the stronger the wind can be. A tornado is a small center of intense low pressure. That pressure drop occurs over a very short distance, which causes air to rush into the tornado rapidly and reach very high speeds in and near the core.
How can Bernoulli's principle be used to predict how a house may be damaged in a tornado?
Bernoulli's principle explains that as wind speed increases, air pressure decreases. In a tornado, high wind speeds can cause a drop in air pressure, increasing the force exerted on a house. This can lead to structural damage as the force of the wind pushes against the walls and roof of the house.
What kind of force does a tornado have which keeps it to have that funnel shaped wind?
The wind in a tornado moves in a circular fashion as it is pulled inward by the pressure gradient force resulting from the low pressure at the center of the tornado.
Is air pressure inside a tornado is lower than outside a tornado?
The air pressure in a tornado is lower than that outside the tornado. That is why the wind blows toward the funnel.
Does high air pressure increase tornado rotation?
High air pressure aloft can increase wind shear, which is a key factor in tornado rotation. Wind shear is the change in wind direction and speed with height, and when it increases due to high pressure systems, it can enhance the rotational capabilities within a storm system and potentially lead to tornado formation.

How does scientist predict a tornado?

Why is debris often described as being sucked in to a tornado?

What are the characteristics of a high-pressure system?
The characteristic is wind and rain because high pressure means wind and rain.
Does a tornado's low air pressure make houses explode?
No. The pressure drop inside a tornado is not large enough for this to happen. Tornadoes tear houses apart with the power of their wind.

Why do the winds in a tornado reach such high speeds?
Winds in a tornado are extremely high because the pressure at the center of the tornado is much less than its surroundings, and this pressure drop occurs over a very small distance. Differences in pressure are what cause most winds. The greater the pressure difference over a given area, the greater the wind speed.
Why do tornadoes have such a high wind speed?
The rotation of a tornado originates from a larger but less intense circulation called a mesocyclone, which creates an area of low pressure. A tornado forms when the mesocyclone tightens and stretches toward the ground. This causes the winds and the low pressure to intensify.
