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.
|About||A hurricane is a cyclone that is located in the North Atlantic Ocean, or the NE Pacific Ocean east of the International Date Line, or the South Pacific Ocean east of 160E, and with sustained winds that reach or exceed 74 mph.||Tropical cyclones in the Northwest Pacific Ocean west of the International Date Line with sustained winds of (or those that exceed) 74 mph are typhoons.|
|Rotation||Clockwise in the southern hemisphere and counterclockwise in the northern hemisphere||Clockwise in the southern hemisphere and counterclockwise in the northern hemisphere|
|Intensity||Hurricanes are classified into five categories according to the Saffir-Simpson Hurricane Wind Scale. The wind speed and intensity of damage increases as from category 1 to category 5.||Typhoons are generally very strong because of the Pacific’s warm water, and therefore are more frequent. They are also classified on the Saffir-Simpson Hurricane Wind Scale, but can also be classified on the Japan Meteorological Agency typhoon scal|
|Location||North Atlantic Ocean, the Northeast Pacific Ocean east of the International Date Line, or the South Pacific Ocean east of 160E. Hurricanes are found near the tropical zone, over warm waters in the Atlantic and Pacific ocean.||Northwest Pacific Ocean west of the International Date Line|
|Most affected areas||Caribbean Sea||South East Asia, China Sea etc.|
|Frequency||10-15 per year||25-30 per year|
|Characteristics||Heavy winds, floods, storm surge, a lot of rain, tornadoes||Heavy winds, floods, storm surge, a lot of rain, tornadoes|
|Occurrence||Usually warm areas||Usually warm areas|

Speed of a typhoon vs. hurricane
A tropical cyclone is one in which the maximum sustained surface wind (using the U.S. 1-minute average) is generally 64 kt (74 mph or 119 km/hr) or more.
Differences in Location
The term hurricane is used for Northern Hemisphere tropical cyclones east of the International Date Lineto the Greenwich Meridian. The term typhoon is used for Pacific tropical cyclones north of the Equator west of the International Date Line i.e. between 100E and 180E in the northern hemisphere.
Differences in Intensity
Typhoons are generally stronger than hurricanes. This is because of warmer water in the western Pacific which creates better conditions for development of a storm. This unlimited amount of warm water also makes for increased frequency of typhoons. Even the wind intensity in a typhoon is stronger than that of a hurricane but they cause comparatively lesser loss due to their location. However, both use the Saffir-Simpson Hurricane Wind Scale for classification.
Direction of Rotation
Some reports also suggest that typhoons can only be counterclockwise ("anti-clockwise" in British English) while hurricanes can be both anti-clockwise and clockwise.
Areas where hurricanes and typhoons occur
Figures suggest the most common area for a Hurricane to occur is the Caribbean Sea while typhoons have a frequent occurrence off the coast of South East Asia.
Names of hurricanes and typhoons
Some commonly occurring hurricanes and typhoons have been named to categorize them. The names of Hurricanes are given each year. A few hurricanes named in the Atlantic in 2007 are Andrea, Barry and Dean. Some Typhoons named in the Western North Pacific and the South China Sea are Damrey, Langwang and Kirogi. Typhoons in the Chinese and Japanese regions are named after living things and often objects like flowers, rivers etc. Check out every hurricane name since 1950.
