Description
English: Map of various index regions used to measure the strength of an ENSO; plotted over a background of the +2 and +3 oC contours of the 1997-8 DJF surface temperature anomaly.
  • 1: [10S, 5S] and [90W, 80W]
  • 2: [5S, Eq] and [90W, 80W]
  • 3: [5S, 5N] and [90W, 150W]
  • 4: [5S, 5N] and [150W, 160E]
  • 3.4: [5S, 5N] and [170W, 120W]

Each index captures different properties; nino3.4 is probably most commonly used.
