Numerical Methods for Global Ocean Models

在这个项目中，P.I.S将研究数值方法，从而开发出适用于气候研究的改进的全球海洋模式。将在原始方程模型和过滤模型(都是由P.I.和合作者开发的)中添加增强功能。主要集中在：1.区域分解策略和边界拟合坐标以添加具有高阶物理特性的边界层；2.高效有限差分格式的守恒性质；3.在较大模式中嵌入混合层的复合重叠网格技术；以及4.PE模式与热带大西洋资料的比较。

In this project, the P.I.'s will investigate numerical methods leading to development of improved global ocean models suitable for climate studies. Enhancements will be added to a primitive equation model and a filtered model (both developed by the P.I. and collaborators). Major focus will be on : 1. Domain decomposition strategies and boundary-fitted coordinates to add boundary layers with higher order physics; 2. Conservation properties of efficient finite difference schemes; 3. Composite overlapping grid techniques for embedding the mixed layer in the larger models; and 4. Comparison of the PE model with tropical Atlantic data.
