AbstractA new operational ice dynamics module has been implemented within the framework of the Canadian Community Ice-Ocean Model. The formulation is based on Hibler�s viscous plastic rheology, a Particle-In- Cell (PIC) approach to model ice advection, and a Zhang-Hibler scheme to solve the momentum equations. The PIC approach reduces numerical diffusion and improves the accuracy of predicting ice edge locations. Discretizing the ice cover into a large number of particles additionally simplifies modelling thickness distribution in great detail, without resorting to complex assumptions concerning a thickness distribution function. The Zhang-Hibler scheme leads to relatively high computational efficiency, and guarantees that the plastic yield conditions are satisfied. The program is tested using idealized cases, which demonstrate the model�s ability to predict ice edge locations, zones of high pressure, and ridging.
