🔍 Key Concepts

• Prevailing westerlies in the Southern Hemisphere • Nickname and typical latitude band of the Roaring Forties • Difference between Northern and Southern Hemisphere mid-latitude wind patterns

💭 Think About

• First, recall in which hemisphere the Roaring Forties occur, then eliminate any answers in the wrong hemisphere. • Think about whether the strongest part of this wind belt tends to be toward the center of the 40s latitude band or toward the edges near 50°. • Consider how the absence of large landmasses in the Southern Ocean affects wind strength as you move poleward from 40° to 50°.

✅ Before You Answer

• Verify which options are in the Southern Hemisphere versus the Northern Hemisphere. • Confirm the usual latitude range of the Roaring Forties (for example, something like 40°–50° in one hemisphere). • Decide whether winds strengthen as you move from 40° toward 50° in that oceanic region.
