During summers, the air is cool, and hence, a high-pressure area develops. Because winds move from high pressure to low-pressure areas, winds blow from the sea to the land (from the Indian Ocean to the Indian mainland) known as the summer monsoon.
Summer Monsoon
- During summers, the land gets more heated than the sea. Because of high temperature, a low-pressure area is created over the land.
- The reverse conditions exist in the oceans. During summers, the air is cool, and hence, a high-pressure area develops. Because winds move from high pressure to low-pressure areas, winds blow from the sea to the land (from the Indian Ocean to the Indian mainland) known as the summer monsoon.
- In the summer months, the landmasses of the Indian subcontinents are heated by the vertical rays of the Sun. This creates a low-pressure area on the land. In the oceans, the high-pressure area develops as the air is cooled. So, the winds blow from the Indian Ocean northwards and in the northwestward direction bringing heavy rainfall to Southeast Asia.
