Modeling Sea Ice as a Granular Material, Including the Dilatancy Effect
A dynamic sea ice model based on granular material rheology is presented. The sea ice model is coupled to both a mixed layer ocean model and a one-layer thermodynamic atmospheric model, which allows for an ice albedo feedback. Land is represented by a 6-m thick layer with a constant base temperature. A 10-year integration including both thermodynamic and dynamic effects and incorporating prescr...
متن کاملDilatancy in slow granular flows.
When walking on wet sand, each footstep leaves behind a temporarily dry impression. This counterintuitive observation is the most common illustration of the Reynolds principle of dilatancy: that is, a granular packing tends to expand as it is deformed, therefore increasing the amount of porous space. Although widely called upon in areas such as soil mechanics and geotechnics, a deeper understan...
متن کاملDilatancy Transition in a Granular Model
We introduce a model of granular matter and use a volume/strain ensemble to analyze infinitesimal shearing. Monte Carlo simulation suggests the model exhibits a second order phase transition associated with the onset of dilatancy.
متن کاملModeling sea ice thickness
In this paper, we present a self contained review on the modeling of sea ice thickness distribution. This is an important quantity arising and contributing to global climate changes. We present the various pde describing it, which are strongly non linear. Detailed mathematical analysis will be reported elsewhere. The utility of this quantity is of course to set up a global analysis of sea, ice ...
متن کاملUsing the material-point method to model sea ice dynamics
[1] The material-point method (MPM) is a numerical method for continuum mechanics that combines the best aspects of Lagrangian and Eulerian discretizations. The material points provide a Lagrangian description of the ice that models convection naturally. Thus properties such as ice thickness and compactness are computed in a Lagrangian frame and do not suffer from errors associated with Euleria...
