Question

Quizplus · Accepted Answer

La Nina conditions are associated with stronger upwelling off the coast of Peru due to the intensification of the trade winds, which push the surface waters away from the coast and allow cold, nutrient-rich waters from deeper regions to rise to the surface. In contrast, during neutral ENSO or El Nino conditions, the trade winds weaken, leading to less upwelling and warmer surface waters.
