Consider the following statements:
1. The winds that blow between 30 degrees N and 60 degrees S latitudes throughout the year are known as westerlies.
2. The moist air masses that cause winter rains in the North-Western region of India are part of westerlies.
Which of the statements given above is/are correct?
Statement 1 is Incorrect: The westerlies blow between 30° and 60° latitudes in both hemispheres, not between 30° N and 60° S.
So, the latitudinal extent mentioned is wrong; it should be 30°–60° N and 30°–60° S. Statement 2 is Correct: The western disturbances that bring winter rainfall to north-western India originate over the Mediterranean region and are carried by the westerlies.
Hence, these moist air masses are indeed part of the westerly wind system.
