<P> Within the Southern Hemisphere tropical cyclones generally form on a regular basis between the African coast and the middle of the South Pacific . Tropical and Subtropical Cyclones have also been noted occurring in the Southern Atlantic Ocean at times . For various reasons including where tropical cyclones form , there are several different ways to split the area between the American and African coasts . For instance the World Meteorological Organization define three different basins for the tracking and warning of tropical cyclones . These are the South - West Indian Ocean between the African Coast and 90 ° E , the Australian region between 90 ° E and 160 ° E and the South Pacific between 160 ° E and 120 ° W . The United States Joint Typhoon Warning Center also monitors the whole region , but splits it at 135 ° E into the South Pacific and the Southern Indian Ocean . </P>
