A cyclone differs from a hurricane or typhoon only on the basis of location.


A hurricane is a storm that occurs in the Atlantic Ocean and north-eastern Pacific Ocean, a typhoon occurs in the north-western Pacific Ocean, and a cyclone occurs in the Indian Ocean.


Cyclones are characterised by inward spiralling winds that rotate about a zone of low pressure.


A cyclone's track is guided over the course of its 2 to 6 day life cycle by the steering flow of the subtropical jet stream.
