What is the tornado air pressure?

The air pressure in a tornado is lower than that of its surrounding but the pressure difference varies with the strength of the tornado. The greater the pressure difference, the stronger the tornado. The greatest pressure drop recorded from a tornado was 100 millibars or about 10%.

What would the air pressure be during a tornado?

Pressure inside a tornado is very low.


Why does a tornado cause low pressure areas?

Air in a tornado is rapidly drawn upward. This creates low pressure as more air rushes in to replace it. However this can ever completely fill the pressure deficit until the upward movement stops.


Does high air pressure increase tornado rotation?

No. Generally the lower the air pressure inside a tornado the faster it rotates.
