Research notes and updates from the team.
The SST anomaly for NINO3.4 during the Jan-Mar season was -0.81 C, and for the month of March it was -0.89 C. The most recent weekly (13 Apr 2022) anomaly in the NINO3.4 region was -0.9 C, suggesting a continuation and slight strengthening of the current weak La Niña event.

Read more →The December SST anomaly for NINO3.4 region (5S-5N; 170W-120W) was -1.05 C, and for Oct-Dec season it was -0.92, which shows weak La Niña. The IRI’s definition of a weak La Niña, like NOAA/Climate Prediction Center’s, requires that the SST anomaly in the NINO3.4 region be between -0.5 C and -1.0 C.
