Table 2.

Reference table for experiment names. BGP CRF and BGM CRF are computed for all participating models. The rest are computed in the experiments with MITgcm only. BGP is ‘Beaufort Gyre Plus’, the wind-forcing pattern corresponding to a strong Beaufort Sea High (Fig. 2a). BGM is ‘Beaufort Gyre Minus’, the wind-forcing pattern corresponding to a weakened Beaufort Sea High (Fig. 2b). CTRL is ‘control’
