A cyclone is any mass of air that spirals around a low pressure center. It is an organized collection of thunderstorms embedded in a swirling mass of air. In general, both typhoons and hurricanes are tropical cyclones but differ in their locations. The difference between hurricane and typhoon is that tropical cyclones in the west Pacific are called Typhoons and those in the Atlantic and east Pacific Ocean are called Hurricanes. It's the longitude that matters.
Depending on its location and strength, a tropical cyclone is referred to by names such as hurricane (/ËhÊrÉ¨kÉn/ or /ËhÊrÉ¨keÉªn/), typhoon /taÉªËfuËn/ , tropical storm, cyclonic storm, tropical depression, and simply cyclone.t the center of a mature tropical cyclone, air sinks rather than rises. For a sufficiently strong storm, air may sink over a layer deep enough to suppress cloud formation, thereby creating a clear  eye . Weather in the eye is normally calm and free of clouds, although the sea may be extremely violent.
