Can interior pressure of a tornado be calculated?

In summary, the interior pressure of a tornado can be calculated by determining the centrifugal speed and radius of the tornado. However, this calculation is simplistic and assumes that the air mass is rotating as a unit with fixed angular velocity and density, which is not entirely accurate. The pressure gradient can be calculated using the density of air and the centrifugal acceleration at a certain distance from the axis. By adding up the pressure gradient along a path from the outside to the center, an answer can be obtained. It is suggested to begin by calculating the centrifugal acceleration at the rim.

Can the interior pressure of a tornado be calculated from the centrifugal speed of the tornado and its radius (centripetal force)? For example, given a tornado with a 1/2 mile radius and a centrifugal speed of 200 mph, how much would the interior air pressure be?

A simplistic calculation would assume that the air mass is rotating as a unit with a fixed angular velocity and a fixed density. [That's wrong, but it's a start].

You could then get the pressure gradient based on the density of air and the centrifugal acceleration at a given distance from the axis. Add up the pressure gradient along a path working from the outside to the center and you have an answer.

Why don't you begin by calculating the centrifugal acceleration at the rim?
 

FAQ: Can interior pressure of a tornado be calculated?

How is the interior pressure of a tornado measured?

The interior pressure of a tornado is measured using a device called a barometer, which measures air pressure. It is typically measured in millibars (mb) or inches of mercury (inHg).

Can the interior pressure of a tornado be predicted?

Yes, the interior pressure of a tornado can be predicted using various atmospheric and meteorological models. However, these predictions are not always accurate and can vary depending on the specific conditions and characteristics of a tornado.

What is the average interior pressure of a tornado?

The average interior pressure of a tornado is around 900 mb, but it can range from 800 mb to 1000 mb. The exact pressure can also vary depending on the size, strength, and location of the tornado.

How does the interior pressure of a tornado affect its strength?

The interior pressure of a tornado is directly related to its strength. A lower pressure indicates a stronger tornado, as it indicates a more intense and tightly-wound vortex of air. The lower the pressure, the faster the winds are rotating within the tornado.

Are there any dangers associated with measuring the interior pressure of a tornado?

Yes, measuring the interior pressure of a tornado can be dangerous as it requires being in close proximity to the tornado. This puts the person at risk of being caught in the strong winds and debris of the tornado. It is not recommended to attempt to measure the interior pressure of a tornado without proper training and equipment.
