FY 2000 Dynamics of Arctic sea ice discussed at workshop Overland, J.E., and J. Ukita Eos Trans. AGU, 81(28), 309, 314, doi: 10.1029/00EO00232 (2000) Sea ice is an interesting geophysical material: it behaves as a large-scale hardening plastic. Consider the impact of the sea-ice covers mechanical behavior on the energy and momentum exchange within the complex atmosphere-ice-ocean system. Sea ice acts as an insulator between the relatively warm ocean water and the cold polar atmosphere. Sea ice cover interacts with the atmosphere by regulating air-sea fluxes, changing surface albedo, and influencing the long-wave radiative balance.
