I keep seeing that Hurricane Milton has record pressure but I don’t understand it. What does pressure of 905 mb mean and why is it important for understanding the size and scale (and potential devastation) of a hurricane?
In: Planetary Science
The pressure in mb helps determine what Category the hurricane will be (along with other factors)
Cat 1: >980 mb
Cat 2: 965-979 mb
Cat 3: 945-964 mb
Cat 4: 920-944 mb
Cat5: <920 mb
