1. A low-pressure zone develops over the Indian subcontinent.
2. Intertropical Convergence Zone or ITCZ shifts towards southwards
Select the correct option from the codes given below:

Answer: [A] Only 1

The monsoon, which is essentially the seasonal reversal in wind direction, causes most of the rainfall received in India and some other parts of the world.

One theory of monsoon highlights the difference between annual temperature trends over land and sea. The apparent position of the Sun with reference to the Earth oscillates from the Tropic of Cancer to the Tropic of Capricorn. Thus the low pressure region created by  solar heating also changes latitude.

The northeast and southeast trade winds converge in this low pressure zone, which is also known as the Intertropical Convergence Zone or ITCZ. This low pressure regions sees continuous rise of moist wind from the sea surface to the upper layers of the atmosphere, where the cooling means the air can no longer hold so much moisture resulting in precipitation.
