Question

Why does Chennai get rain during winters?

Answer 1

Hint:Rain is an important element of the water cycle and is accountable for depositing most of the freshwater on the Earth. It gives enough circumstances for many types of ecosystems. Rainfall in India vastly affected by the Monsoons.

Complete Answer:

-In India monsoons establish an entire season in which the winds reverse totally.

-Chennai is the capital city of Tamil Nadu. It lies on the Coromandel coast on the eastern coast of the Peninsula.

-During summer, Arabian Sea branch of South-west Monsoon ascends the Western Ghats and results in maximum rainfall on its western side.

- On the other hand, the Tamil Nadu coast on which Chennai is situated stays dry due to its location off the way of South-west Monsoon as moving towards east they shed their moisture.

-The North-east dry Monsoon winds blow over the Bay of Bengal during winter.

- As they pass over the Bay of Bengal they develop moisture and bring rain to the Tamil Nadu coast. As now they are under the influence of on-shore winds, they are full of moisture. Chennai is located on the eastern coast. That is why; Chennai obtains rainfall more in winter than in summer.

Note: The rainfall in India is an outcome of the confluence of wind flow from the Bay of Bengal and reverse winds from the South China Sea. The rainy season remains from June to September with a regular annual rainfall between 750–1,500 mm across the region.
