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.

一种模式水是一种特定的水质量，具有水性质的垂直均匀性，例如温度和盐度，在世界各地的亚热带和亚北极地区广泛分布。通过对数值模型和一些数值实验的观测和输出的分析，本研究表明，模式水在形成表面海洋循环及其对大气的影响中的积极作用。我们发现，模式水域的年际变化到际变化的影响及其与全球变暖有关的长期变化对北太平洋循环的影响。在北太平洋中，通过中央模式水产生的东部亚热带逆流可能是通过亚热带逆流引起的空气 - 亚热带模式水的形成，是由中央模式的东部亚热带模式水的形成。
