本文介绍了1958-2004年全球海冰模式的强迫特征。该模型设置的目的是研究在深水质量形成区的变化，因此，在拉布拉多海，格陵兰海，威德尔海和罗斯海的深水形成区的区域更好地解决。海冰模式再现了现实的海冰分布和变化的海冰范围的两个半球，以及海冰运输，比较以及与观测数据。在北大西洋的模式和海洋气象船的数据之间的比较的基础上，我们观察到，垂直结构是很好地捕捉在具有高分辨率的地区。在我们的模式设置，我们能够模拟十年的海洋变化，包括几个盐度异常事件和相应的指纹在垂直水文。该模型设置的海洋状态的特点显着的变化，在大西洋经向翻转环流以及相关的混合层深度模式在北大西洋深水形成区。
The characteristics of a global set-up of the Finite-Element Sea-Ice Ocean Model under forcing of the period 1958-2004 are presented. The model set-up is designed to study the variability in the deep-water mass formation areas and was therefore regionally better resolved in the deep-water formation areas in the Labrador Sea, Greenland Sea, Weddell Sea and Ross Sea. The sea-ice model reproduces realistic sea-ice distributions and variabilities in the sea-ice extent of both hemispheres as well as sea-ice transport that compares well with observational data. Based on a comparison between model and ocean weather ship data in the North Atlantic, we observe that the vertical structure is well captured in areas with a high resolution. In our model set-up, we are able to simulate decadal ocean variability including several salinity anomaly events and corresponding fingerprint in the vertical hydrography. The ocean state of the model set-up features pronounced variability in the Atlantic Meridional Overturning Circulation as well as the associated mixed layer depth pattern in the North Atlantic deep-water formation areas.
