Loss of Hyperbolicity and Ill-posedness of the Viscous–Plastic Sea Ice Rheology in Uniaxial Divergent Flow
Publisher: American Meteorological Society
Abstract: Local contact interactions between sea ice floes can be modeled on the large scale by treating the pack as a two-dimensional continuum with granular properties. One such model, which has gained prominence, is the viscous ...
Sea Ice Ridging Schemes
Publisher: American Meteorological Society
Abstract: As sea ice is advected on the surface of the ocean, the ice concentration (0 ≤ A ≤ 1) and the mean ice thickness change in response to thermodynamic and mechanical forcing. In this paper the authors review the existing ...
Stability of the Viscous-Plastic Sea Ice Rheology
Publisher: American Meteorological Society
Abstract: The large-scale two-dimensional rheology of a sea ice pack arises from the local contact forces between adjacent does in convergence. It is conventionally modeled by a viscous-plastic constitutive relation to reflect the ...
