Abstract

Typically, the ice dynamics component presents the greatest computational burden for sea ice simulation in climate models. Large viscosities in regions of nearly rigid ice impel the use of implicit, iterative numerical methods for the viscous-plastic model, which are time consuming and adapt poorly to parallel computation. To remedy this, we have modified the model by incorporating an elastic closure, which leads to a fully explicit numerical scheme. In addition to facilitating excellent parallel performance characteristics, ramifications of this change include improved accuracy of transient solutions. Recent developments to the elastic-viscous-plastic model further improve the modeled internal ice stress state.
