| 摘 要： | 受南海季风和复杂地形的影响,南海环流场具有复杂的空间结构和明显的季节变化,同时此海域又是中尺度涡多发海域,这些特征必然对南海温跃层深度的水平分布及季节变化有显著影响。首先,基于GDEM(General-ized Digital Environmental Model)的温、盐资料和利用P矢量方法计算并分析了南海的表层环流和多涡结构的空间分布特征和季节变化规律。在此基础上,分析了南海温跃层深度的空间分布特征和季节变化规律。结果表明,南海环流和多涡结构对南海温跃层具有显著的影响。

| Abstract: | Affected by the South China Sea(SCS) monsoon and complex topography,the circulation field in the SCS has complicated spatial structure and obvious seasonal variations,and the meso-scale eddies frequently occurred in the sea area,so these features inevitably affect the horizontal distributions and seasonal variations of the thermocline depth in the SCS.In this paper,the GDEM temperature and salinity data and the P-Vector method are used to compute and analyze the spatial distributions and seasonal variabilities of surface circulation and multi-eddy structure in the SCS,and the spatial distributions and seasonal variabilities of the thermocline depth in the SCS are then analyzed.It is shown from the analysis results that the circulation and multi-eddy structure in the SCS have significant effects on the thermocline in the SCS. |
