Achim Stössel

The results in Stössel (2008) are based on simulations with a global sea ice–ocean general circulation model (GCM) in which the Southern Ocean sea ice component has a higher resolution than the ocean model. Recently, I discovered that the acceleration due to the Coriolis force in the sea ice momentum balance of the high-resolution Southern Ocean sea ice component has erroneously not been engaged. Interestingly, the only noticeable difference to the results presented in Stössel (2008

referred to as SGE06 ), and sea ice concentration ( Lefebvre et al. 2004 ; Liu et al. 2004 ). Screen et al. (2009b) also showed that model resolution does not strongly impact the short-term SST response to the SAM in an ocean model run at various horizontal resolutions. Screen et al. (2009a) showed that the observed negative SST response over the Pacific is associated with negative anomalies in the observed atmosphere-to-ocean heat fluxes, and the observed positive SST response east of Drake

In Michel et al. (2018) , there was a mistake in the Arctic sea ice extent (ASIE) calculation, leading to a few deviations in section 5b, though without changing the overall results. Equation (8) , Table 2 , Fig. 13 , and the affected parts of the text in section 5b should be as follows. Table 2. North Atlantic Oscillation (NAO), Scandinavian blocking (SB), and Arctic sea ice extent (ASIE) indices averaged over the genesis dates for PMCs along with their standard deviations for all polar

should be 1.21 m, which remains a reasonable value. Using the unweighted average in Eq. (13) of A20 amounts to a 1% difference in the estimate of s o / s a compared to using the correct average. Testing of Eq. (13) of A20 with different values of B OLR and B dn (appendix B of A20 ) still yields estimates of s o / s a accurate to within 5% of the (corrected) experimentally derived values.
