Explanation:
Statement I is incorrect: The westerlies blow between approximately 30° and 60° latitude in both hemispheres, but they are not continuous throughout the year. They are prevailing winds that generally blow from west to east, but their strength and position can vary with the seasons.
Statement 2 is correct: The moist air masses that cause winter rains in the northwestern region of India are part of westerlies. This statement is correct. During the winter season, the northwestern region of India experiences winter rains due to the influence of western disturbances. These disturbances are weather systems that form in the westerly wind belt and bring moisture from the Mediterranean region, resulting in rainfall in parts of northwestern India.
