What effects would you expect the Peru and benguela currents to have on the climate of the continents they flow past?

The Peru Current, also known as the Humboldt Current, cools the coastal regions of western South America, leading to arid conditions in countries like Peru and Chile. This results in a desert climate along the coast while promoting upwelling that supports rich marine life. Conversely, the Benguela Current cools the west coast of southern Africa, contributing to a similar aridity in Namibia and parts of South Africa, while also supporting fishing industries through nutrient-rich waters. Both currents significantly influence local climates, creating dry conditions along their coasts.
