Hello, I was just wondering why a hurricane's intensity is judged by their pressure?
Thanks.

Re: Hurricanes and pressure
The lower the pressure, the greater the pressure gradient....this in turn is what causes wind. In general, the lower the pressure, the higher the resulting winds. A hurricane (or any storm) is an area of lower pressure...so the pressure is really the 'driver', not just a 'descriptive' measurement used to assess storm strength.
