How do cyclones, hurricanes and typhoons differ?

CycloneThey are all powerful and spinning storms collectively that are called tropical cyclones, which form over warm tropical waters and reach sustained internal wind speeds of 74 mph.

Hurricanes start in the Atlantic, Caribbean and northeast Pacific, while typhoons form in the western Pacific and southeastern Indian Ocean. If one of these events develops in some parts of the Indian Ocean or part of the southwest Pacific Ocean, it goes by one of three variations of the generic term cyclone.

The storms are named depending on the seasonal lists kept by their respective basin’s monitoring body.

Typhoons and hurricanes and cyclones all rotate in the same direction, counterclockwise, if they form in the Northern Hemisphere. These so-called “backward” storms, which rotate clockwise, form in the Southern Hemisphere, although they are extremely rare in the Atlantic basin. Clockwise-rotating storms are more common in the Indian Ocean and off the coast of Australiaa, however.
