摘要
改进环流模式中的Boussinesq近似与静压近似是当前海洋环流模式的主要研究方向之一。虽然目前已提出一些在模式中包含非Boussinesq效应和静压效应的方法,但是仍有很多关键问题亟待解决。系统地回顾了改进这2个基本近似的理论分析和数值模式的研究进展,介绍了不同方法的理论基础及其数值分析结果,并分析了这些方法中所存在的缺陷和问题,指出了开展进一步研究需要首先分析的几个关键问题。
Improving the Boussinesq approximation and hydrostatic approximation in the ocean circulationmodel is one of important tasks for the circulation model study. Although some methods to include non-Boussinesq and non-hydrostatic effects in ocean model have been suggested, many critical problems remainto be solved. In this paper, the advances in the study on theoretical analysis and numerical model for rela-xing the two approximations in ocean model are reviewed, the theoretical bases and numerical experimentresults of different methods are introduced, the short-comings and problems of these methods are ana-lysed, and some potential problems for the further studies are also pointed out.
