This oceanic event is associated with a fluctuation of a global-scale tropical and subtropical surface pressure pattern called the Southern Oscillation. This coupled atmosphere–ocean phenomenon, with preferred time scales of two to about seven years

  as a two-day forecast was a decade ago. This is true for surface pressure but does vary for other parameters as some types of weather are easier to forecast than others. According to methodology set by the World Meteorological Organization (WMO), the Met Office’s global Numerical Weather Prediction
