Question

Distinguish between northeast monsoon and southwest monsoon.

Answer 1

Hint: Two seasonal winds affect India's climate - the northeast monsoon and the southwest monsoon. After passing the Indian Ocean, the Arabian Sea and the Bay of Bengal, the north-east monsoon, generally known as the winter monsoon, blows from land to sea, while the south-west monsoon, known as the summer monsoon, blows from sea to land. The south-western monsoon brings much of the country's rainfall throughout the year.

Complete answer:
Winds that blow from the poles toward the equator during the Autumnal Equinox cycle (September). They are deflected to the left when they blow from the poles to the equator in the Northern Hemisphere due to the Coriolis effect. Their position is, therefore, North East.
Winds blow to India (towards Equator) all the way from Siberia (near North Pole), but the Himalayas are blocked that do not allow them to reach the plain of the Indo-Gangetic. They're leaving the Northeast Himalayas and joining the Bay of Bengal.

Southwest monsoon:
Along the Indo-Gangetic plain, the southwest monsoon (especially the Bay of Bengal Branch) is losing its moisture. It's time for the autumnal equinox by the time they reach the northwestern parts of India. Low pressure is now going to build in the Bay of Bengal. They are forced to retreat in the same direction as the monsoon is in a trough area of the Indo Gangetic plain with the Himalayas on one side and the Peninsular plateau on the other side. They are thus referred to as retreating monsoons. They do not have rain in the Gangetic plains when retreating as they are still cold and dry from shore winds.

Note: In the Bay of Bengal, both of these winds meet and form a cold and warm front that gives birth to cyclones. Tropical cyclones are the cyclones which develop over the Bay of Bengal. With regard to the equator, the rotation is counterclockwise. Their course will then be East-West. So they are giving rain to India's east coast, especially the Coromandel Coast.
