Anomalous sea-surface temperature (SST) patterns associated with decadal climate variability (DCV) phenomena over the past one year are shown here. The observed SST data used for this analysis were compiled from National Oceanic and Atmospheric Administration (NOAA) Extended Reconstructed Sea Surface Temperature (ERSST) Version 5.
