El Niño - Oscillation Australe ("ENOA"-"ENSO")" />

El Niño/Southern Oscillation (“ENSO”)

A natural coupled mode of climate variability associated with both surface temperature variations tied to El Niño and atmospheric circulation changes across the equatorial Pacific (see also ‘Southern Oscillation Index’). Term was first coined by Rasmusson and Carpenter (1982). More information on ENSO can be found here.
