Abstract

Abstract

In this study,a hybrid Lagrangian-Eulerian(HLE)method is developed for sea ice dynamics.The method adopts the advantages of the high computational efficiency of Particle-in-Cell method(PIC)and the high numerical accuracy of Lagragian Smoothed Particle Hydrodynamics(SPH).In the HLE model,the sea ice cover is represented by a group of Lagrangian ice particles with their own thicknesses and concentrations.These ice variables are interpolated to the Eulerian grid nodes using the Gaussian int erpolation function.Thereafter,the FDM is used to determine the ice velocities on the Eulerian grid nodes,then the velocities of Lagrangian ice particles are interpolated from the grid velocity with the Gaussian function.The Lagrangian ice particles are displaced with the interpolated velocities,and the thicknesses and concentrations of ice particles are then determined based on their new locations.With the HLE numerical model,the ice ridging process in a rectangular pool is simulated,and the simulated results are validated with the analytical solution.The method is also applied to the simulation of sea ice dynamics under vortex wind field.At last,the HLE model is used to simulate the sea ice dynamics of Bohai Sea,and the simulated concentration,thickness and velocity match the satellite images and the field observed data wel.
