What happened

Satellite captures a sea of spinning clouds Lisa Lock Scientific Editor Andrew Zinin Lead Editor Over the Southern Ocean surrounding Antarctica, winds can whip around the globe relatively unimpeded by land.

Why it matters

Intrepid sailors termed these southern latitudes the Roaring Forties, Furious Fifties, and Screaming Sixties on account of the strong prevailing winds.

Common ground

When those winds encounter a barrier like an island, the disruption in airflow can be beautiful.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
