Hindcasts

Browse individual ensemble member Niño index forecasts for any available year/month in the hindcast archive. Each spaghetti line is one member; the thick line is the ensemble median; the dotted black line is the observed value. Observed overlays use detrended observational indices (SST standardized to a fixed 1980-2014 baseline; Niño-3 precipitation shown as anomaly in mm/day).

Multi-centre member plumes

Individual ensemble member trajectories for the selected (year, start month), per centre. Each thin line is one member; thick line is the centre's ensemble median. Select which centres to overlay via the checkboxes above.
