Vast size of Indian continent helps in developing the thermal gradient necessary to attract the vapour laden air from sea. Very high and extensive mountain systems of the Himalayas in the north, extending in an east-west direction, thus posing a formidable physical barrier between tropical and polar air masses. These barriers induce the precipitation of water from moisture laden air. As the air climb up the Himalayas their moisture retention capacity decreases due to cooling effect and this results into high rainfall.

(a) The southwest monsoon brings rains towards the end of summer as the high pressure built in the Indian Ocean pushes the wind masses towards the low pressure formed on land. It’s the temperature variation between the sea and the landmass – sea air being cooler and land being warmer – that causes the action. Also, we have to take an important factor called Temperature Gradient into consideration. It is the Temperature Variation Between The landmass and the surrounding sea.

Which of the statements given above are correct?

(a) 1 and 4

(b) 1 and 2

(c) 1 and 3

(d) 2 and 4

(a) The southwest Monsoon brings rains towards the end of summer as the high pressure built in the Indian Ocean pushes the wind masses towards the low pressure formed on land. The southwestern summer Monsoons occur from July through September. Northern and central Indian subcontinent heats up 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 in to the subcontinent.

As the clouds rise their temperature drops and precipitation occurs.
