2014/12/18
Glaciers and ice caps exhibit currently the largest
cryospheric contributions to sea level rise. Modelling the dynamics and mass balance of the major ice sheets is therefore
an important issue to in...
Description of a hybrid ice sheet-shelf model, and application to Antarctica
3 d ice model hybrid combination shallow ice floating ice shelf grounding line migration parameterized ice flow
<
2014/12/10
The formulation of a 3-D ice sheet-shelf model is described. The model is designed for long-term continental-scale applications, and has been used mostly in paleoclimatic studies. It uses a hybrid com...

During the mid-Pliocene warm period (3.264 to
3.025 million years ago), global mean temperature was similar to that predicted for the next century and atmospheric carbon dioxide concentrations were s...
Better constraints on the sea-ice state using global sea-ice data assimilation
Better constraints sea-ice state global sea-ice data assimilation

2014/12/10
Short-term and decadal sea-ice prediction systems need a realistic initial state, generally obtained using ice–ocean model simulations with data assimilation. However, only sea-ice concentration and v...
A new coupled ice sheet/climate model: description and sensitivity to model physics under Eemian, Last Glacial Maximum, late Holocene and modern climate conditions
A new coupled ice sheet climate model description and sensitivity to model physics Eemian Last Glacial Maximum late Holocene modern climate conditions
<
2014/12/9
The need to better understand long-term climate/ice sheet feedback loops is motivating efforts to couple ice sheet models into Earth System models which are capable of long-timescale simulations. In t...

Seasonal sea ice is an important component of the global climate system. Sea ice influences exchange rates of heat, moisture, and gas between the ocean and atmosphere. Sea ice also plays critical role...
As the last ice age was ending, about 13,000 years ago, a final blast of cold hit Europe, and for a thousand years or more, it felt like the ice age had returned. But oddly, despite bitter cold winter...
No Longer Anchored, Antarctic Ice Stream Surges to Sea--Under-Ice Sub Finds Ridge That May Have Held Back Pine Island Glacier（图）
