Research notes and updates from the team.
The SST anomaly for NINO3.4 during the Jun-Aug season was -0.76 °C, and for the month of August it was -0.98 °C. The most recent weekly (14 Sep 2022) anomaly in the NINO3.4 region was -0.9 °C, indicating persistent weak La Niña conditions. 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.
