Question

Due to which of the following reasons is the southwest monsoons rain bearing winds?
They blow from low pressure area of north-eastern India towards the seas
They are seasonal winds
They blow over warm Indian Ocean and gather moisture
They strike the Himalayas​

Answer 1

Explanation:

These winds rise upwards and give good amount of rainfall to the windward side of western ghats. (iii) When these winds cross the western ghats towards the leeward side they have very less moisture and they descend thus the temperatures increases and also the moisture retaining capacity also increases.

Answer 2

Explanation:

On reaching land, these winds rise because of the geographical relief, cooling adiabatically and leading to orographic rains. This is the southwest monsoon. The reverse happens during the winter, when the land is colder than the sea, establishing a pressure gradient from land to sea.
