About El Niño Monitoring and Outlook
JMA operates the Ocean Data Assimilation System and the El Niño Prediction System
(an ocean-atmosphere coupled model) for monitoring and prediction of El Niño-Southern
Oscillation (ENSO). Diagnosis reports, ENSO monitoring products, ENSO indices and
El Niño outlooks are available on this page monthly.
