Winter Rainfall

11. Winter rainfall in Tamil Nadu is mostly due to- [R.A.S./R.T.S. (Pre) 2010 U.P.P.C.S. (Pre) 2008]

(a) Western disturbances
(b) South-West monsoon
(c) North-East monsoon
(d) South-East monsoon

Correct Answer: (c) North-East monsoon

Solution:The Tamil Nadu coast does remain dry during the South- West monsoon season. This is because it is situated parallel to the Bay of Bengal branch of the South-West monsoon. The prevailing winds during the monsoon season blow from the South-West, bringing moisture-laden winds from the Bay of Bengal towards the Indian subcontinent. However, the Tamil Nadu coast lies in the rain shadow area of the Arabian Sea branch of the South-West monsoon. The Western Ghats mountain range acts as a barrier, blocking the moisture-laden winds from the Arabian Sea, resulting in less rainfall along the Tamil Nadu coast.
Therefore, both the assertion (A) and the reason (R) are true, and (R) provides the correct explanation for (A).

12. Assertion (A): Northern plains of India receive some rainfall in winter. [U.P.P.C.S.(Pre) 1998]

Reason (R) : North East Monsoon is active in winter

(a) Both (A) and (R) are true, and (R) is the corret explanation of (A).
(b) Both (A) and (R) are true, and (R) is not the correct explanation of (A).
(c) (A) is true, but (R) is false.
(d) (A) is false, but (R) is true.A

Correct Answer: (b) Both (A) and (R) are true, and (R) is not the correct explanation of (A).

Solution:The Tamil Nadu coast does remain dry during the South- West monsoon season. This is because it is situated parallel to the Bay of Bengal branch of the South-West monsoon. The prevailing winds during the monsoon season blow from the South-West, bringing moisture-laden winds from the Bay of Bengal towards the Indian subcontinent.

The Western Ghats mountain range acts as a barrier, blocking the moisture-laden winds from the Arabian Sea, resulting in less rainfall along the Tamil Nadu coast.
Therefore, both the assertion (A) and the reason (R) are true, and (R) provides the correct explanation for (A). The retreating winter monsoons pick up some moisture while crossing the Bay of Bengal and cause winter rainfall in Tamil Nadu, south Andhra Pradesh, south-east Karnataka and south-east Kerala (Usually in the first weeks of November). The highest seasonal rainfall of about 75 cm between October and December. Most of it occurs along the south-eastern coast of Tamil Nadu and adjoining parts of Andhra Pradesh. Thereafter, it gradually decreases. The western disturbances also cause a little rainfall in north-west India. The amount of rainfall gradually decreases from the north and north-west to east (it is opposite in rainy season). The northeastern part of India also gets rainfall during the winter months.

13. Given below are two statements, in which one if labelled as Assertion (A) and the other as Reason (R): [U.P. R.O./A.R.O. (Pre) 2023]

Assertion (A): During the winter season, most part of India is dry.
Reason (R): Most parts of the country are under influence of the northeast trade wind during the winter season.
Select the correct answer using the code given below:
Code:

(a) Both (A) and (R) are true and (R) is not the comet explanation of (A)
(b) (A) is false but (R) is true.
(c) (A) is true but (R) is false.
(d) Both (A) and (R) are true but (R) is the correct explanathon of (A).

Correct Answer: (a) Both (A) and (R) are true and (R) is not the comet explanation of (A)

Solution:During the winter season, north-east trade winds prevail over India. Winter Monsoons or the North East Monsoons blow during winter season. Notably these type of winds do not cause rainfall as they more from land to the sea. It is be cause, they have little humidity. Hence, most passes of India do not have rainfall in the winter season. It is important to mention here that, there is an exception, during October and November, northeast monsoon while crossing over the Bay of Bengal, picks up moisture and cause torrential rai fall over the southern state Tamil Nadu.

14. Of the following, the state which receives rainfall in winter season is [44th B.P.S.C.(Pre) 2000]

(a) Kerala
(b) Tamil Nadu
(c) West Bengal
(d) Orissa

Correct Answer: (b) Tamil Nadu
