摘要：在本文中，使用最近开发的盐度-温度（S-T）框架研究了北冰洋的水团转变。该框架允许通过计算 S-T 坐标中的表面和内部扩散通量来简洁地量化水质量变换。这项研究展示了如何通过包括跨区域边界的水团平流交换，将该方法应用于特定的海洋区域（在本例中为北冰洋）。基于全球海洋环流模型的模拟，作者研究了各种参数化混合过程和表面通量对于水穿过北冰洋等盐线和等温表面的转化的重要性。基于模型的结果揭示了一个大致真实的北冰洋，流入的大西洋和太平洋水域在返回北大西洋之前主要被冷却和清新。模型中，T方向的水团变换主要考虑...
AbstractIn this paper, water mass transformations in the Arctic Ocean are studied using a recently developed salinity–temperature (S–T) framework. The framework allows the water mass transformations to be succinctly quantified by computing the surface and internal diffusive fluxes in S–T coordinates. This study shows how the method can be applied to a specific oceanic region, in this case the Arctic Ocean, by including the advective exchange of water masses across the boundaries of the region. Based on a simulation with a global ocean circulation model, the authors examine the importance of various parameterized mixing processes and surface fluxes for the transformation of water across isohaline and isothermal surfaces in the Arctic Ocean. The model-based results reveal a broadly realistic Arctic Ocean where the inflowing Atlantic and Pacific waters are primarily cooled and freshened before exiting back to the North Atlantic. In the model, the water mass transformation in the T direction is primarily acco...
