The anomalous depth of the 20 deg. C isotherm
Base Period for depth anomaly: 1982-present Nino 3.4 Sea Surface Temperature Data: Monthly sea surface temperature on a 1.0 x 1.0 deg. lat/lon grid Base Period for SST anomaly: 1971-2000 Data Source: NCEP, Environmental Monitoring Center, Climate Modeling Branch Description: The red lines in the plots indicate the standardized, anomalous depth of the equatorial Pacific for the various regions indicated on the graphs. "WWV" refers to "warm water volume", which is the depth of water above the 20 deg. C isotherm. Black lines are the standardized NINO 3.4 sea surface temperature anomalies for the period 1982-present. A three-month running average is applied to both time series. NCEP is an acronym for the US National Centers for Environmental Prediction. |
