The SST spatial structure of the third CCA pair (a), explaining 8.8% of variance, together with coupled Arctic SIC (c; 7.7% of variance), T2M (d; 5.0% of variance), and SLP (e; 3.0% of variance) fields north of 50° N for SIC and T2M, and north of 40° N for SLP. The correlation between their corresponding time series (b) is 0.91.
