What is the name of the cold air current flowing along the coast of Chile?

The Humboldt Current is the cold ocean current that flows northward along the coast of Chile. It originates from the southern ocean and is a significant factor in the climate and ecology of the regions it passes through. This current helps to create the unique weather conditions of the area, contributing to the arid climate of northern Chile and the lush, fertile regions in central Chile where the majority of the country’s wine production occurs. The cold temperatures of the Humboldt Current interact with the warmer air to create a climate that is favorable for high-quality grape growing, influencing both the irrigation practices and the types of varieties that can be cultivated successfully.

The other currents mentioned are not related to Chile; the Gulf Stream affects the Atlantic Ocean and climate conditions in North America and Western Europe, the African Current influences the waters off the coast of Africa, and the Equatorial Current moves westward from the Atlantic through equatorial waters. Each of these currents serves its own geographical and climatic role but does not have the same impact on Chile's coastal environment as the Humboldt Current does.
