Both they are strong tropical low air pressures, but described different one occur in separate areas(west Pacific Ocean & Atlantic Ocean).
In meteorology, a tropical cyclone (or tropical disturbance, tropical depression, tropical storm, typhoon, or hurricane, depending on strength and geographical context) is a type of low pressure system which generally forms in the tropics. While they can be highly destructive, tropical cyclones are an important part of the atmospheric circulation system, which moves heat from the equatorial region toward the higher latitudes.
The term used to describe tropical cyclones with maximum sustained winds exceeding 33 meters per second (63 knots, 73 mph, or 117 km/h) depends on the region:
hurricane in the North Atlantic Ocean, North Pacific Ocean east of the dateline, and unofficially in the South Atlantic Ocean
typhoon in the Northwest Pacific Ocean west of the dateline
severe tropical cyclone in the Southwest Pacific Ocean west of 160°E or Southeast Indian Ocean east of 90°E
severe cyclonic storm in the North Indian Ocean
tropical cyclone in the Southwest Indian Ocean and South Pacific Ocean east of 160°E
For the word typhoon two possibilities arise:
From the Chinese 大風 (daaih fūng (Cantonese); dà fēng (Mandarin)) which means "great wind". (Later re-imported back to Chinese as 颱風 táifēng, and 台風 taifu in Japanese).
From Urdu, Persian or Arabic ţūfān (طوفان) < Greek tuphōn (Τυφών).
Portuguese tufão is also related to typhoon.
See tuphōn for more information.
The word hurricane is derived from the name of a native Caribbean Amerindian storm god, Huracan, via Spanish huracán.
The word cyclone came from the Greek word "κύκλος", meaning "circle".
In other areas, hurricanes have been called Bagyo in the Philippines and Taino in Haiti參考資料： myself & wiki

A cyclone is a low pressure atmospheric mass. In the northern hemisphere they rotate counterclockwise. A high pressure mass is called an anticyclone and rotates clockwise.
I've often wondered why we don't have violent high pressure events. Maybe someone could tell me that... ;-)
Anyway, we DO have various violent low pressure events. Under certain circumstances, a cyclonic mass can get itself worked up into a frenzy and it will start winding itself up faster and tighter as conditions permit, until you end up with a hurricane.
Oddly, just a couple of weeks ago I actually heard a weatherman refer to Hurricane Isabel as "a cyclone". This surprised me because I had always held them to be separate entities.
Atlantic hurricanes are birthed almost entirely in one of two places: the Gulf of Mexico and the west coast of Africa. Interestingly (and I may be wrong here), the African low pressure pockets seem to form over land, and then pinwheel on out to sea on a journey to the Caribbean.
Hurricanes and typhoons are the same animal depending on where you live. In the Atlantic (and often the North American Pacific coast, where they are quite rare) they are called hurricanes. Everywhere else in the world they are called typhoons.
Cyclones, hurricanes and tornadoes. To swipe a line from the 3 Stooges, they're all "the same thing...only different".
To go a step beyond your question, tornadoes are a special breed of spinning low pressure air mass. For one thing, we still don't know for sure how they form. One big theory scientists were studying about 10 years ago was the possibility that fluid mechanics generated rapidly spinning HORIZONTAL tubes of air inside storm cells. Somehow these tubes are knocked off kilter and one end of a tube (or tubes) would suddenly start descending towards the ground. (and I now wonder what came of that study/theory?)
Well, that's my 2 cents. Hope it helps...

From my understanding, most of them are same types which describe the Meteorology.
However, there are different areas in the world and scientists use different terminologies to discribe the meteorological phenomena in each area. : )
