NOAA's Climate.gov blog examines why the expected atmospheric response to a warm tropical Pacific was missing for months. In fall 2018 cloudiness over the central Pacific near the Date Line stayed near normal rather than showing the usual El Niño rainfall.
The atmosphere and ocean have now coupled, and NOAA has declared weak El Niño conditions.
This is an explanatory piece on the forecasting of El Niño and does not add a new supply shock. It helps buyers judge how reliable ENSO forecasts are for crop-weather risk.
