Fig. 3: Difference in ocean potential temperature anomalies between FD and SD El Niño.
From: Boosting effect of strong western pole of the Indian Ocean Dipole on the decay of El Niño events

Depth–longitude cross-sections in the tropics (3°S–3°N) of the differences in composite anomalies of 2-month mean ocean temperature (shading; units: °C) between fast and slow decaying El Niño events before the developing years (a–f), during the developing years (g–l), and during the decaying years (m–r) based on the ORAS5 dataset for 1958–2020. Stippling denotes the significant values at the 95% confidence level.
