Indian Ocean:
surface dominated by counterclockwise gyre (broad,
circular system of currents) in the southern Indian Ocean; unique
reversal of surface currents in the northern Indian Ocean; low
atmospheric pressure over southwest Asia from hot, rising, summer
air results in the southwest monsoon and southwest-to-northeast
winds and currents, while high pressure over northern Asia from
cold, falling, winter air results in the northeast monsoon and
northeast-to-southwest winds and currents; ocean floor is dominated
by the Mid-Indian Ocean Ridge and subdivided by the Southeast Indian
Ocean Ridge, Southwest Indian Ocean Ridge, and Ninetyeast Ridge
