In particular, we address the issues raised by the reviewers regarding the sub-selection of SSW events based on the marine cold air outbreak response in the Barents Sea. We have revised our analysis to consider all SSW events, rather than sub-selecting particular SSW events. In addition, we have extended our analysis to explore marine cold air outbreak in three regions of increased cold air outbreak frequency in the North Atlantic: the Barents Sea, the Norwegian Sea and the Labrador Sea (instead of considering the Barents Sea only). By extending the analysis to the entire North Atlantic, we are able to compare the dominant pathways for MCAOs in the Barents and Norwegian Seas to those of the Labrador Sea, and shed light on the spatial variability of the MCAO response after SSW events (shown in Fig. 1f).
