Research notes and updates from the team.
The SST anomaly in the NINO3.4 region attained a weak El Niño level beginning late February 2015, strengthened to moderate strength around mid-May, and strengthened further to a strong level beginning around mid-July. For September the average NINO3.4 SST anomaly was 2.28 C, indicative of strong El Niño conditions, and for June-August it was 1.98 C.

For August the average NINO3.4 SST anomaly was 2.06 C, indicative of strong El Niño conditions, and for June-August it was 1.66 C.

For July the average NINO3.4 SST anomaly was 1.60 C, indicative of strong El Niño conditions, and for May-July it was 1.32 C.

For June the average NINO3.4 SST anomaly was 1.32 C, indicative of moderate Niño conditions, and for Mar-May it was 1.04 C.

Read more →The SST anomaly in the NINO3.4 region has been at a weak El Niño level from late February through mid-May 2015. For April the average NINO3.4 SST anomaly was 0.78 C, indicative of weak Niño conditions, and for Feb-Apr it was 0.64 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.
