During El Nino the situation is reversed. The stable south easterly winds have broken down, and the trade winds are so reduced in strength that they can even change direction close to the equator. Tropical and subtropical warm waters from the Western Pacific spread out eastbound until they reach the South American coast. The wind system of the Walker cell breaks down. It starts to rain on the West side of the Andes, as huge amounts of water evaporate and the water condenses when cooled down during the rise in the atmosphere. The nutricline is much deeper and as a consequence upwelling of nutrient rich deep seawater is reduced, plankton concentration drops and fish will stay out with disastrous decreases in Peruvian fisheries.
