The 'Atacama Desert' in South America is bounded to the west by which cold ocean current that contributes to its hyper-arid climate?

💡 Solution & Explanation

The Humboldt Current, also known as the Peru Current, is a cold ocean current flowing northward along the western coast of South America, chilling the adjacent air mass and inhibiting precipitation to produce the hyper-arid Atacama Desert. Warm currents generally enhance moisture and rainfall, whereas cold coastal currents promote atmospheric stability and aridity. The interaction between ocean currents and continental topography is a core concept tested in climatology.
