Correct Answer: Option (B) — 2, 3 and 4

Concept & Option Breakdown

Standard Reference Verified

Statement 1 is incorrect: The 'Roaring Forties' are strong westerly winds found exclusively in the Southern Hemisphere between 40°S and 50°S latitudes. In the Northern Hemisphere, extensive landmasses break up the zonal continuity of wind flow.

Statement 2 is correct: Due to the unbroken ocean expanse and steep subpolar pressure gradients in the Southern Hemisphere, these westerlies blow with high speed, consistency, and strength.

Statement 3 is correct: Under Coriolis deflection in the Southern Hemisphere, the westerlies blow predominantly from the north-west towards the east.

Statement 4 is correct: These winds bring frequent mid-latitude cyclonic storms, overcast skies, squally showers, and cold, damp ('raw') weather.

Elimination Heuristic & Exam Approach

Eliminate Statement 1: The 'Roaring Forties', 'Furious Fifties', and 'Shrieking Sixties' are unique to the Southern Hemisphere because of the vast, unobstructed southern oceans.
