Three-Month Standardized Monthly SST Anomaly Persistence

This map shows the number of months out of the three months indicated in which the standardized sea surface temperature anomaly exceeded +1 standard deviation or fell below -1 standard deviation of the 1971-2000 mean.

Areas in shades of red on the map show where the standardized sea surface temperature anomaly exceeded +1 standard deviations of the 1971-2000 mean for 2 or 3 months (shown on the color scale legend as 2 and 3) of the three-month period indicated. Areas in shades of blue on the map show where the standardized sea surface temperature anomaly fell below -1 standard deviations of the 1971-2000 mean for 2 or 3 months (shown on the color scale legend as -2 and -3) of the three-month period indicated. The intent of the map is to show where large positive or negative sea surface temperature anomalies have tended to persist during the selected period.

Dataset Documentation

Three-Month Standardized Monthly SST Anomaly Persistence

Data
Reynolds and Smith OISST Version 2 monthly sea surface temperature anomaly (in °C) with respect to the 1971-2000 base period on a 1.0° lat/lon grid
Data Source
NCEP (OISST Version 2)
Analysis
Count of the number of months standardized SST anomalies (with respect to the 1971-2000 climatology) fall below -1 standard deviations of the mean or exceed +1 standard deviations of the mean during a three-month period
