Research notes and updates from the team.
The SST anomaly in the Nino3.4 region in recent weeks has been near the borderline of neutral and El Nino during the mid-May to mid-June period, 2014. For May the Nino3.4 SST anomaly was 0.45 C, indicative of neutral conditions but very close to the borderline of El Nino, and for Mar-May it was 0.16 C.

Read more →The SST anomaly in the Nino3.4 region in recent weeks has been near the borderline between neutral and weak Niña, through mid-February 2014. For January 2014 the Nino3.4 SST anomaly was -0.51 C, indicative of weak La Niña conditions, and for November-January it was -0.18 C.
Read more →The SST anomaly in the Nino3.4 region has been in the neutral range lately, through mid-January 2014. For December 2013 the Nino3.4 SST anomaly was -0.04 C, indicative of neutral ENSO conditions, and for October-December it was -0.12 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.
