What is a humboldt current?

The Humboldt Current, also known as the Peru Current, is a cold oceanic current that flows northward along the western coast of South America, primarily affecting Peru and Chile. It originates near the southern tip of South America and is driven by the trade winds, contributing to the region's rich marine biodiversity and supporting a productive fishing industry. The current significantly influences the climate of the coastal areas, leading to cool, dry conditions. Its upwelling of nutrient-rich waters supports a diverse ecosystem, making it one of the most important ocean currents globally.
