Fig. 1: Shift in the relationship between GBS SIC and CP ENSO.

a The 21-year sliding correlation between different Niño indices and the PC1 of GBS SIC. The green, red, purple, and blue lines represent the SON (September to November), OND (October to December), NDJ (November to January), and DJF (December to February) sliding correlation coefficients, respectively. The black solid (dashed) line represents the 95% (90%) confidence level. DJF GBS SIC (%) anomalies regressed onto the SON NiñoCP index during (b) 1964–1984 (P1) and (c) 1986–2006 (P2). d Correlation coefficients between CP ESNO and GBS SIC in P1 and P2. The dotted regions and asterisks indicate statistical significance at the 95% confidence level based on a two-tailed Student’s t-test.
