ENSO Key Diagnostic Figures

The figures from this page are retrieved from the NOAA Climate Prediction Center (CPC) ENSO monitoring products. They provide a visual summary of the current state of the El Niño–Southern Oscillation (ENSO) and its evolution over time.

Subsurface temperature anomalies

Figure. Subsurface temperature anomalies (°C) relative to the 1991–2020 climatology. Source: NOAA CPC. Cross-section of the tropical basin, along the equator, showing the evolution of subsurface temperature anomalies over time. The vertical axis represents depth (in meters), while the horizontal axis represents longitude (in degrees). Positive anomalies indicate warmer-than-average conditions, while negative anomalies indicate cooler-than-average conditions.
