Research notes and updates from the team.
In January 2024, the sea surface temperatures (SSTs) in the central-eastern equatorial Pacific Ocean experienced a decrease of approximately 0.25 degrees Celsius compared to the previous month. This resulted in the NINO3.4 index reaching +1.78 °C. The weekly-averaged SST anomalies in the NINO3.4 region were +1.70 °C for the week centered on February 07, 2024.
