Once a tropical cyclone reaches maximum sustained winds of 74 miles per hour or higher, it is then classified as a hurricane, typhoon, or tropical cyclone, depending upon where the storm originates in the world. The study of storms can potentially save lives as scientists gain a better understanding of their nature. That's because the typhoon definition is the same as that of a hurricane, cyclone or tropical storm: a giant, rotating system of clouds and storms characterized by low pressure and intensely strong winds. For example, the first hurricane of the season might be Abigail, followed by Bob and Casey.
