Fig. 1: Characteristics of the equatorial Pacific SSTA in observations.
From: The mechanism of boreal summer SSTA phase-locking in the far eastern Pacific
a Peak phase histogram (bars) and seasonal variance (curve) of Niño3.4 SSTA. b Regression (red curve) and correlation coefficients (blue curve) of equatorial SSTA (averaged between 5°S–5°N) against the Niño3.4 index for different longitudes. c SSTA standard deviations of ENSO forcing (red curve) and residual SST components (blue curve) for different longitudes. In (a–c), the vertical lines or shading denote the range of the minimum and maximum values between different observed datasets.
