Paper 1
Revise: Global Distribution and the Role of Atmospheric CirculationTropical cyclones do not form evenly across the world's oceans. Their source areas are mainly warm tropical waters between approximately 5° and 30° north and south of the equator. A source area is where a storm develops; its track is the route it subsequently follows.
Distinguish a source area, where a cyclone forms, from its track, the route it follows. Places affected by cyclones are not necessarily where they formed.
