CURRENTS of the indian ocean

The current systems are largely controlled and modified by landmasses and monsoon winds. Due to surrounding landmass not favourable conditions for the development of permanent and consistent system of ocean currents.

North-east Monsoon Current (warm) blow from land to the ocean during winter season. westward blowing are produced currents between Andaman and Somali. Monsoon Wind

(2) Indian Counter Current (warm) Indian counter current is originated during winter season (northern hemisphere). This current flows in easterly direction between 20-8°S latitudes from Zanzibar to Sumatra.

(3) S.W. Monsoon Current (warm) during summer season. Direction is from south-west to north-east. Monsoon Wind

(4) Indian S. Equatorial Current (warm) flows from east to west between 10°S and 15°S latitudes from Australian coast to African coast. obstructed by Madagascar this current is divided into many branches.

(5) Mozambique Current (warm) One branch of the southern Indian equatorial current . moves southward through Mozambique Channel joins the Agulhas current near 30°S.

(6) Madagascar Current This Current is flows northwards near the western coast of Madagascar. it is the only current which sailors can employ on trips from southern Africa to India.

(7) Agulhas current This Current is the Western Boundary Current of the southwest Indian Ocean. It flows down the east coast of Africa from 27°S to 40°S. It is narrow, swift and strong. It is the largest western boundary current in the world ocean.

(8) West Wind Drift (cold) produced due to eastward blowing westerlies ('roaring forties‘). bifurcates in two branches near 110°E long. One branch turns northward and flows as West Australia cold current and merges with the south equatorial current near 100°E long. The second branch of the west wind drift turns southward.
