1.1Northern Indian OceanNorthern Indian ocean lies in the tropics and is land locked on the northern side. NorthernIndian ocean experiences the semi-annually reversing monsoon winds blowing from northeastduring December-Apriland from southwest during June-September. The surface winds areconsistent in their direction during these period and are famously known as the Northeastmonsoon and Southwest monsoon. There are also exist inter-monsoon periods in between themonsoons, characterized by weak and variable winds, intense summer heating in May and mildheating during October.The sea bottom slopes up towards the north and merges with the continental shelf. TheIndian peninsula divides the north Indian Ocean into the Arabian Sea and Bay of Bengal. Thoughthese marginal seas occupy the same latitudinal range, the water characteristic exhibit widedifferences, which bring both the oceanographers and meteorologist to a common platform ofunderstanding the monsoons, their response on these marginal seas in respect of climaticvariability and livingresources for the benefit of people. These marginal seas are forced by theabove wind systems, solar heating owing to the lower latitude, the immense evaporation,precipitation, particularly during the southwest monsoon period, and the huge river run off,particularly in the Bay of Bengal. The circulation, especially in the equatorial region, differsmarkedly from the other two oceans. The Arabian Sea is connected to the warm and highly salinewaters of the Persian Gulf and Red Sea.1.2Southern Indian OceanThe characteristics of the south Indian Ocean are similar to those of the south Atlanticand south Pasific. These three oceanic regions are interconnected at the polar latitudes and formthe southern ocean, the circulation of the south Indian Ocean encompasses a large subtropicalgyre with an intense western boundary current off the Agulhas coast, generally known as the
Agulhas Current. The south Indian Ocean is connected to the Pasific Ocean at the low latitudesan d also at the higher southern latitudes, south of Australia. It is connected to the southernAtlantic Ocean at higher southern latitudes and is known to effect the circulation of the BenguelaCurrent off the South African coast.Southwest monsoon during June to October and tropicalcyclones occur during May/June and October/November in the northern Indian Ocean andJanuary/February in the southern Indian Ocean.
