Describe the mechanism of monsoons.
Answers
Due to Sun, there is differential heating of land and water. The Intertropical Convergence Zone or ITCZ shifts over Ganga plains during the Summer. Due to strong vertical air currents and formation of high pressure over Tibetan plateau, the plateau gets intensely heated during the summer. ...
Explanation:
Answer:
the monsoons are experienced in the tropical area roughly between 20degreeN and 20degreeS. to understand the mechanism of the monsoons the following facts are important.
Explanation:
1. the differential heating and cooling of land and water creates low pressure on the land mass of India while the seas around experience comparatively high pressure.
2. the shift of the position of intertropical convergence zone ITCZ in summer over the Ganga plain (this is the equatorial trough normally positioned about 5 degree north of the equator. it is also known as the monsoon trough during the monsoon season).
3. the presence of the the high pressure area east of Madagascar, approximately at 20 degree south over the Indian Ocean the intensity and position of this high pressure area affects the Indian monsoon.
4. the Tibetan plateau gets intensely heated during summer which results in strong vertical air currents and the formation of low pressure over the plateau at about 9 km above sea level.
5. the movement of the westerly jet stream to the north of the Himalayas and the designs of the tropical easterly jet stream over the Indian peninsula during summer.
