Explanation

Statement 1 – 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 – 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.
