A mode water is a particular water mass with vertical homogeneity of water properties such as temperature and salinity, distributed widely at subtropical and subarctic regions all over the world. From an analysis of observations and outputs of numerical models and some numerical experiments, the present study showed the active role of mode waters in the formation of surface ocean circulation and its impacts on the atmosphere. We found the influence of interannual to decadal variations of mode waters and their long-term changes associated with global warming on the North Pacific ocean circulation. In the North Pacific, the eastern subtropical countercurrent, which is generated by central mode water, is found to be possibly responsible for the formation of another mode water, eastern subtropical mode water, through air-sea interaction caused by the subtropical countercurrent.

模态水是一种具有温度、盐度等水性质垂直均匀性的特殊水团，广泛分布于全球亚热带和亚北极地区。本文通过对数值模式的观测和输出以及一些数值实验的分析，揭示了模式水在海洋表层环流的形成及其对大气的影响中的积极作用。我们发现了模态水的年际和年代际变化及其与全球变暖相关的长期变化对北太平洋环流的影响。在北太平洋，通过副热带逆流引起的海气相互作用，发现由中央模态水产生的副热带东部逆流可能是形成另一模态水——副热带东部模态水的原因。
