Give a geographical reason:
Gyre develops in the Southern Indian Ocean.
Gyre develops in the Southern Indian Ocean because -
- A gyre is a circular pattern of ocean currents. It is influenced by the shape of the coastline its extent and the peculiar arrangement of the wind system prevailing in the region.
- The current system in the southern part of the Indian Ocean leads to the development of a large gyre.
- The two major arms of this gyre are:
- The south equatorial current flowing east to a west direction under the influence of easterlies.
- The 'West Wind Drift' flowing from west to east under the influence of westerlies.
- The circulation is completed in the west by Mozambique-Agulhas currents and in the east by West Australian currents. It is considered to be one of the major gyres on a global scale.
