摘要

海洋模型设计的一个重要方面是垂直坐标系的选择。传统的海洋模式使用单一坐标类型来表示垂直方向,但在欧洲(北大西洋模式动力学- DYNAMO) (Willebrand等人,2001年)和美国(数据同化和模式评估实验- DAMEE) (Chassignet等人,2000年)进行的模式比较工作表明,目前使用的三个主要垂直坐标(深度[z-水平]、密度[等平层]或地形跟踪[sigma水平])都不能单独使用。在海洋的任何地方都是最佳的。混合坐标海洋模型(HYCOM) (Bleck, 2002)被配置为结合所有这三种垂直坐标类型。它在开阔的、分层的海洋中是等平的,但使用分层连续性方程来动态平滑地过渡到浅海岸区域的地形跟踪坐标,以及混合层和/或非分层海洋的z级坐标。混合坐标将传统等流坐标环流模式的地理适用范围扩大到浅海近岸和世界大洋的非分层地区。它保持了等压模式在分层区域的显著优势,同时在近地表和浅海岸区提供了更高的垂直分辨率,从而更好地代表了上层海洋物理

Global Ocean Prediction Using HYCOM
One important aspect of ocean model design is the choice of the vertical coordinate system. Traditional ocean models use a single coordinate type to represent the vertical, but model comparison exercises performed in Europe (DYnamics of North Atlantic MOdels - DYNAMO) (Willebrand et al., 2001) and in the United States (Data Assimilation and Model Evaluation Experiment - DAMEE) (Chassignet et al., 2000) have shown that none of the three main vertical coordinates presently in use (depth [z-levels], density [isopycnal layers], or terrain-following [sigma-levels]) can by itself, be optimal everywhere in the ocean. The HYbrid Coordinate Ocean Model (HYCOM) (Bleck, 2002) is configured to combine all three of these vertical coordinate types. It is isopycnal in the open, stratified ocean, but uses the layered continuity equation to make a dynamically smooth transition to a terrain-following coordinate in shallow coastal regions, and to z-level coordinates in the mixed layer and/or unstratified seas. The hybrid coordinate extends the geographic range of applicability of traditional isopycnic coordinate circulation models toward shallow coastal seas and unstratified parts of the world ocean. It maintains the significant advantages of an isopycnal model in stratified regions while allowing more vertical resolution near the surface and in shallow coastal areas, hence providing a better representation of the upper ocean physics
