Numerical Modeling of the Ice-tide Interaction in the ArcticOcean

北冰洋冰盖通过控制大气和海洋之间的动量和热量交换，在全球气候中发挥着重要作用。冰的分布不仅决定着热平衡，而且还通过冷季排盐水和暖季冰融化来影响海洋密度分布。大气和水之间交换水和热的强烈过程发生在冰盖的开口处。该项目是由美国国家科学基金会的北极系统科学计划推动的关于北极环境及其在全球变化中的作用的系统研究的一部分。这是一个为期两年的项目，利用俄罗斯圣彼得堡北极和南极研究所现有的数据集以及提高灵敏度的现有和改进的模型来评估潮汐对冰产生和冰与海洋相互作用的影响。这项研究将调查四个基本的潮汐成分，空间分辨率约为20公里，以及潮汐在海冰铅形成中的作用。

The ice cover in the Arctic Ocean plays an important role in the global climate by controlling exchange of momentum and heat between the atmosphere and the ocean. Ice distribution defines not only the heat balance but it also influences the oceanic density distribution through the brine rejection during the cold season, and ice melting during the warm season. The strong processes of exchanging moisture and heat between atmosphere and water occur at the pack-ice openings. This project is part of a systematic study of the Arctic environment and its role in global change which is promoted by NSF's Arctic System Science Program. It is a two year project to utilize data sets existing in the Arctic and Antarctic Research Institute, St. Petersburg, Russia with existing and refined models of increased sensitivity to evaluate the effect of tides on ice production and ice-ocean interaction. This research will investigate four basic tidal constituents, with space resolution of about 20 kilometers, and the role of tides in sea-ice lead formation.
