| abstracts | The paper deals with the problem of sea-ice pack motion and deformation under the actionof wind and water drag forces. Differential equations describing the behaviour of ice, with itsvery distinct material responses in converging and diverging flows, express the mass and linearmomentum balances on a horizontal plane (the free surface of the ocean). The thermodynamiceffects (ice melting and lead water freezing) are accounted for by adding source terms to theequations describing the evolution of the ice thickness and area fraction (concentration). Thesethermodynamic source terms are described by means of a single function that idealizes typicalice growth-rates observed in winter in the Arctic. The equations governing the problem aresolved by a fully Lagrangian method of the smoothed particle hydrodynamics (SPH). Assum-ing that the ice behaviour can be approximated by a non-linearly viscous rheology, the proposedSPH model was used to simulate the flow of a sea-ice pack driven by wind drag stresses andvarying seasonal temperatures. The results of numerical simulations illustrate the evolution ofan ice pack, including distributions of ice thickness and ice area fraction in space and time forassumed temperature distributions. |
