Fig. 1: Quasi-decadal SST variance maps.
From: Synchronous decadal climate variability in the tropical Central Pacific and tropical South Atlantic
Maps of the decadal SST standard deviation (shading, unit: K) on an 8–16-year frequency band and its variance ratio (contours, units: %) relative to the raw SST anomaly during the a March to August (MAMJJA) and b September to February (SONDJF) seasons for the period 1951–2022. The blue dashed boxes enclose the Niño4 (160° E–150° W, 5° S–5° N) and tropical South Atlantic (40° W–10° E, 15° S–0° N) regions.
