The goal of this chapter is to present sea ice in relation to S2S prediction. The field of S2S prediction attempts to bridge the gap between numerical weather prediction (NWP) and climate prediction. Interestingly, thus far, the role of sea ice on subseasonal climate predictability is not well understood. From the existing literature, which mostly deals with seasonal-to-interannual timescales, we will review the sources of sea ice predictability at timescales from 2 weeks to 1 year. Based on this
analysis, we will characterize the predictability of the second kind as related to sea ice and provide an overview of our understanding of the possible role of sea ice as a source of S2S atmospheric predictability, in the polar regions and beyond.
