Anomalous Depth of the Equatorial Pacific Thermocline
Heat Storage Based on:
The anomalous depth of the 20°C isotherm from monthly Global Ocean Data Assimilation System (GODAS) potential temperature
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 thermocline for the various regions indicated on the graphs. "WWV" refers to "warm water volume", which is the depth of water above the 20°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.
