Where does this measuring system come from? Web10 mrt. 2024 · " This is a term assigned to a storm that experiences a pressure drop of 0.71 of an inch of mercury (24 mb) in 24 hours or less. When the pressure drop occurs in the center of the storm, it creates a giant vacuum effect. Air then rushes in toward the center in the form of powerful winds, sometimes similar to how a hurricane develops.
