(WMC) - Hurricane, cyclone, typhoon, they are all the same, officially known as tropical cyclones. The only difference between storms, is that different parts of the world use different terms.
Hurricanes are used in the Atlantic, Caribbean Sea, along with the central and northeast Pacific. The storm becomes a typhoon in the northwest Pacific. In the Bay of Bengal and the Arabic Sea, they are called cyclones, whereas tropical cyclones are used in the southwest Indian Ocean, the name chances slightly to severe tropical cyclone in the southwestern Pacific and southeastern Indian Ocean.
For a storm to gain a typhoon, cyclone or hurricane status, it must reach 74 mph wind strength. Just like we use five category strengths when describing hurricanes, other parts of the world use the same scale. Australia has a different system for categorizing storm strength.
If the storm rotates in a different direction than what we consider "normal" then the storm is most likely in the southern hemisphere. North of the equator the storms rotate counterclockwise, south of the equator they rotate clockwise. This has to do with what we call the Coriolis effect, in turn is influenced by the rotation of the Earth.
The Seasons do vary from place to place, the Atlantic and central Pacific Hurricane seasons are from June 1st through November 30th. Eastern Pacific is from May 15th through November 30th. Northwestern Pacific season is close to all year, with May through November. The cyclone season in the South Pacific and Australia runs from November to April. The Bay of Bengal has two seasons, April to June and September to November.
