Research notes and updates from the team.
The SST anomaly in the NINO3.4 region has been mostly at a weak El Niño level from mid-October through mid-April 2015. For March the average NINO3.4 SST anomaly was 0.58 C, indicative of weak Niño conditions, and for Jan-Mar it was 0.56 C. The IRI’s definition of El Niño, like NOAA/Climate Prediction Center’s, requires that the SST anomaly in the Nino3.4 region (5S-5N; 170W-120W) exceed 0.5 C.

For December the average NINO3.4 SST anomaly was 0.78 C, indicative of weak Niño conditions, and for Oct-Dec it was 0.71 C.

For November the average NINO3.4 SST anomaly was 0.85 C, indicative of weak Niño conditions, and for Aug-Oct it was 0.60 C.
Read more →The SST anomaly in the NINO3.4 region has hovered near or just below the threshold of the level required for El Niño level, beginning in early November the weekly SST anomalies have started exceeded it. For October the average NINO3.4 SST anomaly was 0.49 C, indicative of borderline Niño conditions, and for Aug-Oct it was 0.38 C.
