Future Antarctic bed topography and its implications for ice sheet dynamics
Future Antarctic bed topography ice sheet dynamics
2015/1/6
The Antarctic bedrock is evolving as the solid Earth responds to the past and ongoing evolution of the ice sheet. A recently improved ice loading history suggests that the Antarctic Ice Sheet (AIS) ha...
TWP-ICE试验期间一次热带深对流过程的拉格朗日输送特征
热带深对流 卷云砧 水凝物输送 拉格朗日轨迹 FLEXPART扩散模式
2014/9/26
本文使用高分辨率WRFV3.4.1模式对TWP-ICE试验期间的一次热带深对流过程进行了数值模拟，利用第四重嵌套每五分钟输出一次的模拟资料对对流系统的上升气流质量通量廓线特征进行了分析，并结合FLEXPART拉格朗日粒子扩散模式对热带深对流系统进行拉格朗日轨迹分析.质量通量廓线特征及拉格朗日轨迹的分析结果表明，在条件不稳定层顶附近便有部分水凝物被输送出深对流系统.深对流系统中的水凝物主要沿环境引导...
Basal roughness of the Institute and Möller Ice Streams, West Antarctica: Process determination and landscape interpretation
Antarctica Roughness Radio-echo sounding Ice dynamics Mö ller Ice Stream Institute Ice Stream
2014/5/20
We present a detailed analysis of bed roughness beneath Institute and Möller Ice Streams, west Antarctica, using radio-echo sounding data (RES) acquired in the austral summer of 2010/11. We asses...

On the Parametrization of Basal Heat Flux for Sea-ice Modelling
Arctic oceanography climate modelling climate change ice-ocean heat flux
2009/6/10
A sea-ice model is used to investigate the ice-ocean heat flux that occurs at the base of the ice. The source of this basal heat flux is supposed in reality to arise from physical processes (e.g. ocea...
Comparisons Between Observed and Simulated Ice Motion in the Northern Baltic Sea
Sea ice model ice dynamics ice drift Baltic Sea
2009/6/10
Sea ice drift in the coastal ice zone of the Bothnian Bay was measured with five GPS drifters in March 1997. To model coastal ice dynamics, the viscous-plastic ice model of Hibler with a fine spatial ...
Classification of Large-Scale Sea-Ice Structures Based on Remote Sensing Imagery
Sea ice fracture mechanics remote sensing deformation
2009/6/10
An analysis of satellite and aerial images of the sea-ice in the Baltic Sea was performed to trace mechanical phenomena. Characteristic structures of deformed thin-ice cover are described. Parallel fa...
Modelling of Superimposed Ice Formation and Sub-Surface Melting in the Baltic Sea
Baltic Sea sea ice thermodynamics superimposed ice sub-surface melting
2009/6/9
Superimposed ice formation and sub-surface melting were modelled using a one-dimensional
thermodynamic sea ice model with the Baltic Air-Sea-Ice Study (BASIS) field data. During a thermal equilibrium...
On the Shape of the Fast Ice - Drift Ice Contact Zone
fast ice boundary fracture mechanics Baltic Sea
2009/6/9
The location and the geometry of the fast ice zone are examined in the Bay of Bothnia, Baltic Sea.Remote sensing images were collected from the fast ice – drift ice boundary zone showing that the fast...
