9503895 A study of key aspects of the hydrodynamics and thermodynamics of the large scale ocean circulation will be conducted in the theoretical framework provided by the flux form of the potential vorticity (PV) equation and the associated theorems of 'invertibility' and 'impermeability'. The geographical distribution of PV and PV flux lines will be mapped, to the extent that models and climatological data allow it, and the resulting patterns studied and interpreted. Using a hierarchy of models and theory, the physics of, and the global connections between, the 'entry' and 'exit' points of potential vorticity will be exposed and their dependence on the interplay of mechanical and thermodynamical forcing at the boundary of the ocean elucidated.

9503895将在位涡（PV）方程的通量形式和相关的“可逆性”和“不可渗透性”定理提供的理论框架内对大尺度海洋环流的流体动力学和热力学的关键方面进行研究。在模型和气候数据允许的范围内，将绘制PV和PV通量线的地理分布图，并研究和解释由此产生的模式。使用层次结构的模型和理论，物理的，和全球之间的连接，“入口”和“出口”点的位涡将被暴露和它们的依赖于相互作用的机械和物理强迫在海洋的边界阐明。
