Fig. 1: The anomaly correlation coefficient (ACC) and ACC difference for detrended annual mean salinity and temperature at lead years 3–5.
From: North Atlantic subpolar gyre provides downstream ocean predictability
ACC between hindcast and ASSIM for (a) sea surface salinity (SSS), b sea surface temperature (SST) for the period 1970–2019. c ACC difference between SSS and SST in hindcast. d ACC in hindcast (solid line) and persistence (dash line) for salinity (red) and temperature (blue) at different depths in the Nordic Seas for the period 1975–2019. Stippling in (a)-(c) denotes the ACC or ACC difference is significant at 95% confidence level based on block bootstrapping. Yellow shading in (d) denotes the ACC difference between salinity and temperature in hindcast is significant at 95% confidence level based on block bootstrapping. The box outlined in black in (a)–(c) shows the area used to calculate the ACC in the Nordic Seas.
