Fig. 1: Spatio-temporal evolution of El Niño events.
From: Projections of faster onset and slower decay of El Niño in the 21st century
Longitude-time diagrams of monthly sea surface temperature anomalies [top row, °C] in the equatorial Pacific (averaged 5°S–5°N), composited over El Niño events from a CMIP6 21st Century (21 C) ensemble mean (2051–2100) and b CESM-LENS 21 C (2051–2100). Also shown are the 21 C minus 20th Century (20 C, 1951–2000) difference from c CMIP6 and d CESM-LENS. Similarly, panels e–h show the composites of precipitation anomalies [mm day−1]. Ordinate represents time from January of the onset year (Year 0) to December of the decay year (Year 1). Hatching on panels c, d, g, and h indicates statistical significance at the 95% confidence level using a bootstrapping technique (see Methods).
