Consider the following statements: 1. The winds which blow between 30 N and 60 S latitudes throughout the year are known as westerlies. 2. The moist air masses that cause winter rains in North- Western region of India are part of westerlies. Which of the statements given above is/are correct?
Correct Answer: B. 2 only
Explanation: The analysis of the statements: The statement "The winds which blow between 30°N and 60°S latitudes throughout the year are known as westerlies" is incorrect because westerlies blow in the mid-latitudes, roughly between 30° and 60° both north and south of the equator. The statement incorrectly mixes north and south latitudes. The statement "The moist air masses that cause winter rains in the North-Western region of India are part of westerlies" is correct. The winter rains (often called Western Disturbances) in north-western India are brought by the moisture-laden westerly winds originating from the Mediterranean region. Hence, only statement 2 is correct. The correct answer is (b) 2 only.
