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

The correct option is B 2, 3 and 4
The Roaring Forties are strong westerly winds found in the Southern Hemisphere, generally between the latitudes of 40 and 50 degrees.The strong west-to-east air currents are caused by the combination of air being displaced from the Equator towards the South Pole and the Earth's rotation, and there are few landmasses to serve as windbreaks. The Roaring Forties were a major aid to ships sailing the Brouwer Route from Europe to the East Indies or Australasia during the Age of Sail, and in modern usage are favoured by yachtsmen on round-the-world voyages and competitions. The boundaries of the Roaring Forties are not consistent, and shift north or south depending on the season.
