Question

Explain the phenomena and mechanism of the monsoon winds.

Answer 1

The monsoon is a seasonal modification of the general planetary wind system. Monsoon winds are most powerful in India and China. During summer, the interior of Asia and India become the center of great heat and powerful low pressure develops there. On the other hand, the water surface of the India ocean remain cooler and the pressure gradient is towards the heated interior. The wind blows from water to land it is moist and brings lots of rain.

In Winter season, the interior of Asia and India sub-continent is cold and high pressure develops there. On the other hand, the ocean surface is warmer and the pressure gradient is towards the ocean. As the wind comes from the interior, it is cold and dry.
