In the context of global ocean currents, how do surface circulation patterns in the Arabian Sea reverse on a seasonal basis compared to most other world oceans?
A. They remain permanently stationary due to equatorial landmass blocking.
B. They reverse their direction biannually in response to the seasonal monsoon wind reversals (clockwise in summer, counter-clockwise in winter).✓ Correct Answer
C. They flow exclusively from east to west throughout the year driven by lunar tides.
D. They are entirely controlled by cold meltwater discharge from Arctic ice shelves.
💡 Solution & Explanation
Surface currents in the Arabian Sea reverse direction biannually in direct response to the seasonal southwest and northeast monsoonal winds. Unlike most oceanic basins with permanent circulation gyres, the northern Indian Ocean is uniquely land-locked to the north. This meteorological phenomenon influences regional climate patterns and marine productivity.
