Concept: The storm is the same, the name just differs with the ocean basin.
Detail: Each year around 50 storms roam the tropical oceans with winds reaching greater than 74 miles per hour. Their spawning grounds are the earth's tropical oceans. Strangely enough, hurricanes do not form directly on the equator and rarely within 5 deg north to 5 deg south latitude. They do not often develop more than 25 - 30 deg north or south of the equator. Storms reaching 75 mph are called hurricanes in the Atlantic and eastern Pacific, typhoons in the western Pacific, and cyclones in the Indian and South Pacific (once called "willy willies" as well as cyclones.) Speaking of names, it has become the practice worldwide to name individual storms. The origin of this practice is somewhat uncertain. An Australian meteorologist named Clement Wraage, at the turn of the 20th century, was noted for naming extratropical storms after the wives of politicians, particularly those he didn't favor. During World War II and shortly thereafter US Navy hurricane hunters found it useful to name individual storms to avoid confusion when several were in progress at once. Thus hurricanes "Able", "Baker", "Charley", "Easy" came into being for several years. Beginning in 1953, they were routinely assigned girls names with the unending rash of jokes about "unpredictability." More politically correct alternating male and female naming came in practice in 1979 in the US.
