Read the following Assertion (A) and Reason (R) carefully and choose the correct option:
Assertion (A): The retreating monsoon winds are associated with dry weather and clear skies in northern India.
Reason (R): During the retreating monsoon, the low-pressure area over the northern plains is replaced by a high-pressure system.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Both A and R are true, and R is the correct explanation of A.
During the months of October and November, the apparent movement of the sun towards the south weakens the low-pressure trough over the northern plains. This is gradually replaced by a high-pressure system, causing the monsoon winds to withdraw or retreat. As these winds move away from the land toward the sea, they result in clear skies and a rise in temperature. While the weather becomes dry in northern India, this period is often marked by high humidity, a phenomenon known as "October heat."
