The Roaring Forties are powerful westerly winds found in the Southern Hemisphere between 40° and 50° latitude. They are caused by air moving from subtropical highs toward the poles. Because the Southern Hemisphere has very little land to slow the air down, these winds blow with immense force and consistency, creating the rough seas and loud noise for which they are named. ANSWER: (A) Strong winds blowing near 40° latitude in the Southern Hemisphere
What is the Roaring Forties? (A) Strong winds blowing near 40° latitude in the Southern Hemisphere (B) Ocean current at 40° South latitude (C) Ocean current at 40° North latitude (D) None of these

This term describes the persistent westerly winds that dominate the Southern Ocean. Unlike the Northern Hemisphere, where continents like Eurasia and North America create friction that breaks up wind patterns, the Southern Hemisphere is mostly water. This lack of physical obstacles allows the winds to build up incredible momentum. The Roaring Forties are essential for the global climate as they help drive major ocean currents and distribute heat around the planet. Historically, they were a double-edged sword for sailors: they allowed ships to travel very fast across the ocean, but the violent waves and stormy weather made navigation extremely dangerous.
