摘要

陆冰是附着在海岸上的近乎不动的海冰。尽管陆冰具有改变海冰和海洋属性的潜力,但大多数最先进的海冰模型对陆冰的表现不佳。在这里,我们研究了陆冰形成和稳定的两个关键过程,即海冰抗拉强度和海床-冰龙骨相互作用。我们利用全球海洋-海冰耦合模型 NEMO-LIM3 研究了这些过程对北极海冰覆盖层和卤化层的影响。我们的研究表明,将海底-冰龙骨应力包括在内,可以改善拉普捷夫海和东西伯利亚海陆冰覆盖的季节性和空间分布。这种改进的陆冰表现形式将有缺陷的多冰带的位置设定在大约大陆架断裂带上方的新位置。海冰拉伸强度对北极卤化层稳定性的影响要有效得多。将这一过程纳入模型后,北极海冰群会更厚、更固结、移动性更弱,从而使海洋和大气进一步分离。因此,与不包括海冰抗拉强度和海床-冰龙骨应力的参考模拟相比,美洲(欧亚)北极卤化层的可用势能减少(增加)了(\(\sim \)30kJ/m\(^2\) (\(\sim \)30kJ/m\(^2\)) 。我们的研究结果突出表明,需要更好地理解陆冰物理过程及其对海洋和海冰状态的影响。

Influence of the representation of landfast ice on the simulation of the Arctic sea ice and Arctic Ocean halocline

Landfast ice is near-motionless sea ice attached to the coast. Despite its potential for modifying sea ice and ocean properties, most state-of-the-art sea ice models poorly represent landfast ice. Here, we examine two crucial processes responsible for the formation and stabilization of landfast ice, namely sea ice tensile strength and seabed–ice keel interactions. We investigate the impact of these processes on the Arctic sea ice cover and halocline layer using the global coupled ocean–sea ice model NEMO-LIM3. We show that including seabed–ice keel stress improves the seasonality and spatial distribution of the landfast ice cover in the Laptev and East Siberian Seas. This improved landfast ice representation sets the position of flaw polynyas to new locations approximately above the continental shelf break. The impact of sea ice tensile strength on the stability of the Arctic halocline layer is far more effective. Incorporating this process in the model yields a thicker, more consolidated, and less mobile Arctic sea ice pack that further decouples the ocean and atmosphere. As a result, the available potential energy of the Arctic halocline is decreased (increased) by \(\sim \)30kJ/m\(^2\) (\(\sim \)30kJ/m\(^2\)) in the Amerasian (Eurasian) compared to the reference simulation excluding sea ice tensile strength and seabed–ice keel stress. Our findings highlight the need to better understand landfast ice physical processes conjointly with the subsequent influences on the ocean and sea ice states.

期刊介绍: Ocean Dynamics is an international journal that aims to publish high-quality peer-reviewed articles in the following areas of research: Theoretical oceanography (new theoretical concepts that further system understanding with a strong view to applicability for operational or monitoring purposes); Computational oceanography (all aspects of ocean modeling and data analysis); Observational oceanography (new techniques or systematic approaches in measuring oceanic variables, including all aspects of monitoring the state of the ocean); Articles with an interdisciplinary character that encompass research in the fields of biological, chemical and physical oceanography are especially encouraged.
