Modeling Arctic sea ice with an efficient plastic solution
A computationally efficient numerical method is developed for solving sea ice momentum equations that employ a nonlinear viscous-plastic rheology. The method is based on an alternating direction implicit (ADI) technique that involves a direct solution of the momentum equations. This method is therefore more computationally efficient than those employing an iterative procedure in solving the equ...

متن کاملOn an efficient numerical method for modeling sea ice dynamics
A computationally efficient numerical method for the solution of nonlinear sea ice dynamics models employing viscous-plastic rheologies is presented. The method is based on a semi-implicit decoupling of the x and y ice momentum equations into a form having better convergence properties than the coupled equations. While this decoupled form also speeds up solutions employing point relaxation meth...
متن کاملArctic Sea Ice Extent Prediction
Climate change is a pressing and present issue which has come to be at the forefront in the last few decades. As such, understanding climate change is of utmost importance. In addition to environmental impact, these changes will have social and economic ramifications as these changes will affect the way in which we utilize land and sea resources in the future. The minimum annual arctic sea ice ...
متن کاملScaling Properties of Arctic Sea Ice Deformation in a High‐Resolution Viscous‐Plastic Sea Ice Model and in Satellite Observations
Sea ice models with the traditional viscous-plastic (VP) rheology and very small horizontal grid spacing can resolve leads and deformation rates localized along Linear Kinematic Features (LKF). In a 1 km pan-Arctic sea ice-ocean simulation, the small-scale sea ice deformations are evaluated with a scaling analysis in relation to satellite observations of the Envisat Geophysical Processor System...
