Fig. 2

a The leading empirical orthogonal function (EOF1) of detrended sea level in satellite observation (1993-present). b The EOF1 of detrended sea level in SPEAR reanalysis since the satellite era. c The EOF1 of sea level in SPEAR control simulation. The contours in (a–c) are the sea level pressure (SLP) regressions upon the sea level EOF1 timeseries. d The first principal component (PC1) of sea level in satellite observation (blue line) and SPEAR reanalysis (red line). e Power spectrum of the PC1 of sea level in SPEAR control simulation. f Regression of Atlantic streamfunction against the sea level timeseries in SPEAR reanalysis (shading). The contours denote the long term mean Atlantic meridional overturning circulation (AMOC) state. g Same as (f) but for the SPEAR control run. The units for the sea level EOF1, PC1, SLP regression and the Atlantic streamfunction regression are mm, 1, hPa and Sv, respectively.
