Extended Data Fig. 4: Model supports for the mechanism of the mode water controlled by the AMV.
From: North Pacific subtropical mode water is controlled by the Atlantic Multidecadal Variability
a, Regressions of the SST (shading, unit in oC) and surface wind filed (vector, unit in m/s) with respect to the AMV index derived from the pre-industrial model simulation (PI-Control EXP.). Green line indicates the transect A (150°E, 20°-50°N). b, Temperature regressed upon the AMV index, derived from the PI-Control EXP., along transect A. c, Time series of mode water mean temperature and the normalized model AMV index (red) from the PI-Control EXP. smoothed by a 7-year low-pass filter. Correlation coefficient between the mode water mean temperature and the model AMV at zero lag is 0.76. The shading shows the one standard deviations of its time series.
