Nino-34 EMR Forecast

Comparison with CA Model


Last updated: 11/11/09

The NINO-34 ensemble forecast (600 members) of nonlinear model is based on data from January 1950 through October 2009 (blue), and ensemble mean (red) predicts moderate El-Nino peaking by the end of 2009. 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.
