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?
Explanation
The Roaring Forties are strong westerly winds found between 40° and 50° latitudes in the Southern Hemisphere, known for their strength due to the absence of major landmasses.
Statement 1 is incorrect: These winds are exclusive to the Southern Hemisphere, as large landmasses in the Northern Hemisphere disrupt wind flow.
Statement 2 is correct: The Roaring Forties are driven by strong pressure gradients between the subtropical high-pres-sure belt and subpolar low-pressure zone, with the Southern Hemisphere’s vast oceans enhancing their consistency.
Statement 3 is correct: The Coriolis effect causes a deflection of these winds, giving them a north-west to east trajectory.
Statement 4 is correct: These winds carry moisture, often resulting in stormy, rainy conditions, especially in the Southern Indian and Pacific Oceans.
