ABSTRACT
Buoy observations of sea ice drift show that sea ice motion and deformation contain substantial high-frequency variability at subdaily timescales. However, numerical simulations of the sea ice dynamics normally do not include processes on such short timescales. Instead, by applying traditional water-drag formulations for the ocean-sea ice boundary layer, the inertial frequencies tend to be omitted in the spectra of modeled sea ice motion and deformation due to fictitious ocean damping. Here a dynamic-thermodynamic sea ice model is presented that includes "inertial embedding" of the sea ice into the oceanic boundary layer to reproduce sea ice motion and deformation not only at ...
