3. Assertion (A): Anti-cyclonic conditions are formed in winter season when atmospheric pressure is high and air temperature is low. [I.A.S. (Pre) 2001]

Reason (R) : Winter rainfall in Northern India causes development of anticyclonic
conditions with low temperature.

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

Correct Answer: (c) (A) is true, but (R) is false (d) (A) is false, but (R) is true

Solution:Rainfall during winter in northern India is due to the western disturbance. Anti-cyclonic conditions in India already exist and it has nothing to do with winter rains. Anti-cyclonic conditions during winter are formed when the atmospheric Pressure is high and the temperature is low. Therefore, Assertion (A) is correct and Reason (R) is wrong.

4. Which of the following areas of India receives winter rainfall? [U.P.P.C.S.(Mains) 2012]

(a) North-West
(b) South-West
(c) North-East
(d) South-East
(e) North-West & South-East

Correct Answer: (e) North-West & South-East

Solution:The North-Western region of India receives rainfall in winters due to western disturbance. Additionally, the coastal areas of Tamil Nadu in South-East India receives rainfall during the winter due to the northeast monsoon.

A-In northwestern India, western disturbance causes rainfall in Punjab, Haryana, Delhi and western Uttar Pradesh.

B-During October and November, north-east monsoon while crossing over the Bay of Bengal picks up moisture and causes rainfall over Tamil Nadu coast, southern Andhra Pradesh, southeast Karnataka and southeast Kerala.

5. The winter rains caused by Western disturbance in North Western Plain of India gradually decrease from: [U.P.P.C.S.(Pre) 2019]

(a) East to West
(b) West to East
(c) North to South
(d) South to North

Correct Answer: (b) West to East

Solution:The winter rains caused by western disturbance in North Western Plain of India gradually decreases from West to East. The extratropical storm originating in the Mediterranean region that brings sudden winter rain to the north-western parts of the Indian sub-continent is called Western Disturbance. It is non-monsoonal precipitation pattern driven by the westerlies. Western Disturbance plays an important role in bringing moderate to heavy rain in low-lying areas and heavy snow to mountainous regions of Indian sub-continent, especially in winter. This precipitation has great importance in agriculture, particularly for the Rabi crops.

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

Assertion (A): Rabi crops in India are predominantly cultivated in north-western states like Punjab and Haryana.

Reason (R) : The success of Rabi crops in these states depends on the rain due to western extra tropical cyclones during winters.
Select the correct answer using the code given below:
Code:

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

Correct Answer: (a) Both (A) and (R) are true and (R) is the correct explanation of (A).

Solution:In India, the Rabi crops is harvested Primarily in States like Punjab and Haryana in the north western region, although Rabi crops are also grown in other parts in India. Rabi crops are winter crops.

It is harvested in northern India, mainly in the northwest- ern region, during the winter season, predominantly in the Indo-Gangetic Plains. Notably, Extra Tropical cyclones are steered by the subtropical westerly jet streams, originating from Turkey, Iraq, Iran, Afghanistan and Pakistan. It mostly affect north western India (entire northern India) and leads to winter rains, which are essential for Rabi crops.

Both (A) and (R) are true and (R) is the correct explanation of (A).

7. Which one of the following causes is responsible for rainfall during winters in north-western part of India? [U.P.P.C.S.(Pre) 2021]

(a) Retreating Monsoon
(b) Cyclonic depression
(c) Western disturbances
(d) South-West Monsoon

Correct Answer: (c) Western disturbances

Solution:The western disturbance is responsible for the winter rains in the North-West part of India, but the Western disturbance is a weak form of Cyclonic disturbance. In this form, it also comes under Cyclonic depression, but Western disturbance will be the correct answer as the most suitable option.

8. India's Northern plains get winter rainfall due to- [U.P.P.C.S.(Pre) 1993]

(a) Western Disturbance
(b) Monsoon in Bay of Bengal
(c) Monsoon in Arabian sea.
(d) Retreating Monsoon.

Correct Answer: (a) Western Disturbance

Solution:India' northern plains get winter rainfall due to a western disturbance. Western disturbance is an extratropical storm originating in the Mediterranean region that brings sudden winter in the north-western part of the Indian subcontinent

9. Which of the following regions of India receives winter rainfall? [R.A.S./R.T.S (PRE) 1999]

(a) Odisha - Karnataka
(b) Punjab - Tamil Nadu
(c) Arunachal Pradesh - Bihar
(d) Tamil Nadu - Karnataka

Correct Answer: (b) Punjab - Tamil Nadu

Solution:Coastal areas of Tamil Nadu receive winter rainfall up to 65-75cm due to retreating North-East Monsoon. Additionally, Punjab also receives winter rainfall due to Western Disturbance.

10. Given below are two statements, one is labelled as [U.P.P.C.S.(Pre) 2023]

Assertation (A) - The Tamil Nadu coast remains dry during South-West monsoon season.
Reason (R)- The Tamil Nadu coast is situated parallel to the Bay of Bengal branch of South-West monsoon and it lies in the rain shadow area of the Arabian Sea branch of the South-West monsoon during monsoon season.

Select the correct answer using the code given below:
Code:

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

Correct Answer: (d) Both (A) and (R) are true and (R) is 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. 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).
