Peru Coastal Currents During El Niño: 1976 and 1982

Year-long measurements of subsurface current and temperature on Peru's continental shelf included the onset of El Niño in 1976 and 1982. The Peru Coastal Undercurrent more than doubled in speed and advected anomalously warm water poleward. El Niño began in different seasons in 1976 and 1982, but the current and temperature responses were very similar. Acceleration of poleward flow at 10°S occurred several days after sea level rose at the Galápagos Islands in October 1982, suggesting the onset of El Niño propagated as a Kelvin wave.
