el Nino

a warm-water current which periodically flows south along the coast of Ecuador and which affects the climate throughout the Pacific; it is associated with the Southern Oscillation of the atmosphere. At approximately seven-year intervals the equatorial counter-current strengthens and warm surface waters cover the cold waters off Peru. This affects the plankton and fisheries adversely, causing poor breeding seasons for the seabirds.
