Potential ocean–atmosphere preconditioning of late autumn Barents-Kara sea ice concentration anomaly
Many recent studies have revealed the importance of the climatic state in November on the seasonal climate of the subsequent winter. In particular, it has been shown that interannual variability of sea ice concentration (SIC) over the Barents-Kara (BK) seas in November is linked to winter atmospheri...
