| Shown above is the SST anomaly forecast for Nino region 3.4 from the Climate Predication Center (CPC) Climate Forecast System. The dashed lined represents the average of the range of solutions (red and blue lines) provided by the forecast model. El Nino is defined as a three month average SST anomaly of +0.5 or greater. La Nina is defined as a three month average SST anomaly of -0.5 or less. |
Shown above is a planview of the CPC Climate Forecast System SST anomaly seasonal forecast. Warm colors indicate above normal SST values and cold colors below normal SST values. El Nino (La Nina) is defined by warmer (cooler) than nromal waters across the eastern equitorial Pacific. |
