Which currents are absent in the northern part of the Indian Ocean and why?
The cold currents are absent in the northern part of the Indian Ocean. Cold ocean current flows from polar region to equator. The Indian Ocean is land-locked in the North. Hence, no cold current can enter the north part of the Indian ocean.
Why is there no North Equatorial Current in the Indian Ocean?
The North Equatorial current and counter equatorial current is absent in summer. Due to the influence of south-west monsoon and the absence of north-east tradewinds, a strong current flows from west to east in the summer season.
Why the currents of the Indian Ocean are different than any other ocean?
Because most of the air pressure gradient is retained behind the Tibetan plateau, air pressure gradients over the Indian Ocean and the gyre are small. Due to this seasonal wind cycle, the currents of the Indian Ocean, which make up the Indian Ocean gyre, are directly affected, causing reversal.
Which ocean current does not belong to Indian Ocean?
In the following ocean currents, ‘Benguela’ is a cool stream flowing in the Southern Atlantic Ocean, whereas Agulhas and Mozambique are the hot stream flowing in the Indian Ocean near the East African coast and the southern Indian Ocean is the cold stream.
Is the Indian Ocean current warm or cold?
List of Ocean Currents of the World
Name of Current | Nature of Current |
---|---|
North-East Monsoon Current | Cold and unstable |
Somali Current | Cold and unstable |
Western Australian Current | Cold and Stable |
South Indian Ocean Current | Cold |
What were the winds that blew in the Indian Ocean called?
the seasonal wind of the Indian Ocean and southern Asia, blowing from the southwest in summer and from the northeast in winter. (in India and nearby lands) the season during which the southwest monsoon blows, commonly marked by heavy rains; rainy season. any wind that changes directions with the seasons.
Which current is associated with Indian Ocean?
Somali Current, surface current of the western Indian Ocean, caused during the northern summer months by the blowing of the southwest monsoon along the coast of East Africa, moving coastal waters northeastward along with it for about 950 miles (1,500 km), with surface velocities reaching up to 9 miles (14 km) per hour.
Why are there ocean gyres?
Three forces cause the circulation of a gyre: global wind patterns, Earth’s rotation, and Earth’s landmasses. Wind drags on the ocean surface, causing water to move in the direction the wind is blowing. The Earth’s rotation deflects, or changes the direction of, these wind-driven currents.
What is the origin of the returning seasonal winds in India?
The Thar Desert and adjoining areas of the northern and central Indian subcontinent heat up considerably during the hot summers. This causes a low pressure area over the northern and central Indian subcontinent. To fill this void, the moisture-laden winds from the Indian Ocean rush into the subcontinent.
Why India does not have autumn and spring?
Trees that drop their leaves annually in this manner are called deciduous trees. Tropical regions (of which India is one) are close to the Equator, and they receive strong sunlight all year long. And that is precisely why these regions may not have the four seasons (Spring, Summer, Autumn and Winter).
