HE44E:
Sea Ice Dynamics and Predictability II Posters

Session ID#: 84695

Session Description:
The evolution of sea ice on seasonal, interannual and decadal timescales is vital to polar oceans and global climate. Bulk sea ice characteristics such as volume, concentration, thickness, floe-size distribution, albedo, melt-pond fraction, and fracture statistics, depend crucially on mechanical and thermodynamical sea ice response to atmospheric and oceanic forcing. Sea-ice predictions are complicated by the lack of optimal models for its deformation and thermodynamics that are appropriate across scales ranging from centimeters to hundreds of kilometers. Further complications arise due to transitions between the continuous and discrete element (i.e., individual floes) nature of sea ice dynamics that occur, for example, in marginal ice zones. Recent rapid increases in both computational capabilities and availability of extensive high-resolution sea-ice observations provide opportunities for developing and testing new mathematical frameworks for sea ice modeling, data assimilation, and prediction. This session invites contributions involving analyses of both remote and in-situ data, as well as numerical and theoretical process modeling to constrain sea-ice growth/melt and mechanical deformation processes in order to improve future sea-ice predictions.
