(1) SST: Sea Surface Temperature. (2) SST Anomaly: the Sea Surface Temperature Anomaly represents the deviation between the SST model and a SST reference (here, the reference is the 2005 Levitus climatology). (3) Mean: mean of the indicator model values over the NWS region for the indicated day. (4) Monthly Tendency: slope of linear fit to values over the 30 latest days.
