Simulation of the Atlantic Circulation with a Coupled Sea Ice-Mixed Layer-Isopycnal General Circulation Model. Part II：Model Experiment
Atlantic Circulation Sea Ice-Mixed Layer-Isopycnal General Circulation Model
2008/12/18
An ocean general circulation model (OGCM) formulated on isopycnal coordinates is used to model the circulation of the Atlantic. The model domain is bounded meridionally at 30°S and the North Pole and ...
Simulation of the Atlantic Circulation with a Coupled Sea Ice-Mixed Layer-Isopycnal General Circulation Model. Part I：Model Description
Atlantic Circulation Sea Ice-Mixed Layer-Isopycnal General Circulation Model
2008/12/18
A diabatic ocean general circulation model based on primitive equations is described. It uses isopycnals as Lagrangian coordinates in the vertical and predicts a free surface. Prognostic fields of tem...
A Numerical Simulation of Sea Ice Cover in Hudson Bay
Numerical Simulation Sea Ice Cover Hudson Bay
2008/12/17
Hibler's dynamic-thermodynamic sea ice model with viscous-plastic rheology is used to simulate the seasonal cycle of sea ice motion, thickness, compactness, and growth rate in Hudson Bay under monthly...
Effect of Sea Ice on the Salinity of Antarctic Bottom Waters
Antarctic Bottom Waters Sea Ice
2008/12/12
Brine rejection during the formation of Antarctic sea ice is known to enhance the salinity of dense shelf waters in the Weddell and Ross Seas. As these shelf waters flow off the shelves and descend to...
Enhanced tropospheric BrO over Antarctic sea ice in mid winter observed by MAX-DOAS on board the research vessel Polarstern
tropospheric BrO Antarctic sea ice MAX-DOAS Polarstern
2008/12/12
We present Multi AXis-Differential Optical Absorption Spectroscopy (MAX-DOAS) observations of tropospheric BrO carried out on board the German research vessel Polarstern during the Antarctic winter 2...
The large-scale two-dimensional rheology of a sea ice pack arises from the local contact forces between adjacent does in convergence. It is conventionally modeled by a viscous-plastic constitutive rel...
As sea ice is advected on the surface of the ocean, the ice concentration (0 A 1) and the mean ice thickness change in response to thermodynamic and mechanical forcing. In this paper the authors rev...
Asymptotic Stability of the Viscous–Plastic Sea Ice Rheology
Asymptotic Stability Viscous–Plastic Sea Ice Rheology
2008/12/3
The stability of the viscous–plastic rheology used extensively to model the dynamics of large–scale sea ice covers is studied. Using energy methods, it is shown that on a bounded domain, the viscous–p...
Modeling Sea Ice as a Granular Material, Including the Dilatancy Effect
Modeling Sea Ice Granular Material Dilatancy Effect
2008/12/3
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 f...
First-year sea-ice contact predicts bromine monoxide (BrO) levels at Barrow, Alaska better than potential frost flower contact
sea-ice BrO levels Alaska potential frost
2008/12/1
Reactive halogens are responsible for boundary-layer ozone depletion and mercury deposition in Polar Regions during springtime. To investigate the source of reactive halogens in the air arriving at Ba...
An Elastic–Viscous–Plastic Model for Sea Ice Dynamics
Arctic Ice Dynamics Joint Experiment Parallel Ocean Program elastic–viscous–plastic
2008/11/26
The standard model for sea ice dynamics treats the ice pack as a visco–plastic material that flows plastically under typical stress conditions but behaves as a linear viscous fluid where strain rates ...
Information on the early Holocene climate constrains the summer sea ice projections for the 21st century
holocene climate ice projections
2008/11/7
The summer sea ice extent strongly decreased in the Arctic over the last decades. This decline is very likely to continue in the future but uncertainty of projections is very large. An ensemble of exp...
The Impact of Southern Ocean Sea Ice in a Global Ocean Model
Southern Ocean Global Ocean Model Sea Ice
2008/10/24
Most of the Southern Ocean (SO) is marginally stably stratified and thus prone to enhanced convection and possibly bottom-water formation whenever the upper ocean is cooled or made more saline by ice ...
Loss of Hyperbolicity and Ill-posedness of the Viscous–Plastic Sea Ice Rheology in Uniaxial Divergent Flow
Loss of Hyperbolicity Ill-posedness Viscous–Plastic Sea Ice Rheology Uniaxial Divergent Flow
2008/7/23
Local contact interactions between sea ice floes can be modeled on the large scale by treating the pack as a two-dimensional continuum with granular properties. One such model, which has gained promin...

Effects of Rheology Ice Thickness Distribution Dynamic–Thermodynamic Sea Ice Model
2008/7/22
Realistic treatment of sea ice processes in general circulation models is needed to simulate properly global climate and climate change scenarios. As new sea ice treatments become available, it is nec...
