Question

What causes the monsoon? 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. The primary

cause of monsoons is 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

Inter tropical Convergence Zone or ITCZ. This low-pressure region 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. The rainy seasons of

East Asia, sub-Saharan Africa, Australia and the southern part of North

America coincide with the shift of ITCZ towards these regions.

Q.2b) What do you understand by ITCZ?​

Answer 1

Answer:

The Intertropical Convergence Zone, or ITCZ, is the region that circles the Earth, near the equator, where the trade winds of the Northern and Southern Hemispheres come together. The intense sun and warm water of the equator heats the air in the ITCZ, raising its humidity and making it buoyant.
