Wind wave generation in the ice-covered ocean

A wind wave generation model for the ice-covered ocean is proposed in the present study. Boundary layer flows are considered to model the wind velocity profile on the ice upper surface. The ice cover is modeled as a viscoelastic layer, and the water part is modeled as the inviscid fluid. The present model is based on the two dimensional linear flow-instability theory. Non-slip boundary conditions are employed on the air-ice interface. Both normal and shear stress boundary conditions are matched on the air-ice interface. It is shown that the model converges to the field and experimental data for open water cases. The ice elasticity is found as the critical factor to generate the wind wave. The generation of the flexural-gravity wave and elastic waves in ice is analyzed.
