What observations do Peruvian fishermen make that indicate El Nino is coming?
El Niño/La Niña-Southern Oscillation, or ENSO, is a quasiperiodic climate pattern that occurs across the tropical Pacific Ocean roughly every five years. El Nino refers to the cooling of the surface of the tropical eastern Pacific Ocean.El Niño events begin when trade winds, part of the Walker circulation, falter for many months. A series of Kelvin waves cross the Pacific along the equator and create a pool of warm water near South America. ChaCha!
