Consider the following statements about the 'Roaring Forties': 1. I. They blow uninterrupted in the Northern and Southern Hemispheres. 2. II. They blow with great strength and constancy. 3. III. Their direction is generally from North - West to East in the Southern Hemisphere. 4. IV. Overcast skies, rain and raw weather are generally associated with them. Which of these statements are correct?

1. The question asks to identify the correct statements about the 'Roaring Forties'. 2. Statement I is incorrect. The Roaring Forties are a phenomenon primarily of the Southern Hemisphere, known for being largely uninterrupted by landmasses there. This is not the case in the Northern Hemisphere at the same latitudes. 3. Statement II is correct. These Westerlies blow with significant strength and constancy in the Southern Hemisphere due to the lack of land barriers. 4. Statement III is correct. As Westerlies in the Southern Hemisphere, their general direction, influenced by the Coriolis Effect, is from the North-West towards the East/South-East. 5. Statement IV is correct. The zone of the Roaring Forties is known for its stormy weather, including overcast skies and frequent rain, associated with the passage of low-pressure systems. 6. Correct statements are II, III, and IV.
