Numerical and Theoretical Analysis of Shallow Water Flow with Applications to the Global Oceanic Circulation

9730518 KNIO该项目是对重力波在全球海洋环流长期演变中的作用进行数值和理论研究。所使用的模型是罗格斯大学开发的SEOM，并将实施多压力变量方法。这将导致SEOM效率的数量级提高，从而允许扩展高分辨率海洋模拟，其中包括对自由表面现象的充分表示。该模型将首先用于对全球海洋中的潮汐循环进行二维模拟。在模式优化后，将对全球风生环流进行扩展的三维模拟。

9730518 Knio The project is for numerical and theoretical study of the role of gravity waves in the long-time evolution of the global oceanic circulation. The model used is SEOM developed at Rutgers University, and an multiple-pressure- variable approach will be implemented. It would lead to an order-of-magnitude enhancement in the efficiency of SEOM, thus allowing extended high-resolution ocean simulations that include adequate representation of free-surface phenomena. The model will first be used for two-dimensional simulations of tidal circulation in the global ocean. After the model is optimized, extended three-dimensional simulations of the global wind-driven circulation will be performed.
