Short summary

This study underscores the significance of early sea ice dynamic processes and mesoscale air-ice-sea coupling interactions in shaping sea ice variability. The ocean-ice coupling process exerts positive feedback on January sea ice in the Bering Sea, while the atmosphere-ice coupling processes contribute to negative feedback. The 40-year fluctuation of sea ice area is intricately governed by the competition between ocean-ice coupling processes and atmosphere-ice coupling processes.
