Nino-34 EMR Forecast

Comparison with CA Model


Last updated: 1/12/12

The NINO-34 ensemble forecast (300 members) of EMR model is based on data from January 1950 through December 2011 (blue), and ensemble mean (red) predicts La-Nina conditions in winter 2011/12. The error bars (black) correspond to one standard deviation of the ensemble plume. You can also check a multi-model plume of Nino-34 forecasts from different statistical and dynamical models (including our UCLA-TCD model) maintained by IRI, and compare predictions for the past 22 months; see the historical performance of the UCLA-TCD model here.
