What effect does the Peru Current have on western coast of South America?
As it is a cold current, except at times of the phenomenon known as El Niño (q.v.), the Peru Current brings fog to the nearby coast but also helps to keep the coast one of the most intensely arid areas in the world.
How do ocean currents affect Chile?
THE HUMBOLDT CURRENT, also known as the Peru Current, is an ocean current that flows along the western coast of South America, affecting the water and air temperatures of coastal CHILE and PERU. … Its chilled air carries less moisture, thus helping to create the world’s driest desert in Chile’s Atacama Desert.
Why is Peru so arid on the West?
Its extreme aridity is caused by the upwelling of cold coastal waters and subtropical atmospheric subsidence, but it is also subject to occasional flooding during El Niño years. In 1728, the town of Sechura was destroyed by a tsunami and was later rebuilt in its present location.
How does the Peru Current affect climate?
The Peruvian Current affects Peru year round, and moderates the climate of Chile in spring and summer, when it displaces a subtropical center of high pressure. Ordinarily the coast of Chile would warm in spring and summer, but the onset of the Peruvian Current diminishes temperatures and forestalls any rain.
How does the Humboldt ocean current impact the western coast of South America?
The Humboldt Current is a cold water current that flows northward from Antarctica, along the western coast of South America. This current creates an upwelling of nutrients along the coast. These nutrients are responsible for creating a highly productive ecosystem that is rich in biodiversity.
Which current is cold current?

Why is the water so cold in Chile?
The Humboldt Current, running from the Pacific Ocean, bisects in both northern and southern direction when meeting the Chilean coast at the altitude of Puerto Montt. The northern stream runs as far as Peru, flowing alongside the entire Chilean coast, resulting in a constant flow of cold water on the Chilean beaches.
Is the ocean cold in Chile?
Chile water temperature today
Sea water temperature in some cities of Chile is above 20°C and it is enough for comfortable bathing. The warmest sea temperature in Chile today is 20.5°C (in Anakena), and the coldest water temperature is 5.6°C (Puerto Natales).
Is Agulhas current warm or cold?
One of the fastest-flowing currents in any ocean, it reaches an estimated top speed of 5.8 miles (9.3 km) per hour off the southeast coast of South Africa. Because it is fed from lower latitudes, the Agulhas Current is warm, ranging in temperature from 57 to 79 °F (14 to 26 °C) at the surface.
Who discovered the Peru Current?
Spanish interest in the west coast of South America grew after Vasco Núñez de Balboa discovered the Pacific Ocean in 1513, but it was not until 1524 that Francisco Pizarro, aided by another soldier, Diego de Almagro, and a priest, Hernando de Luque, undertook explorations that led to the conquest of Peru.
How fast is the Peru Current?
About 20 percent of the world’s catches are extracted from the Humboldt Current. The surfacing of cold water and its equatorward flow (at an average speed of 10 knots [11.5 miles, 18.5 kilometers) per hour is caused by wind shear against the coast.
How fast is the Florida Current?
The velocity of the current is fastest near the surface, with the maximum speed typically about 5.6 miles per hour (nine kilometers per hour). The average speed of the Gulf Stream, however, is four miles per hour (6.4 kilometers per hour).
