为了理解太平洋区域热、盐比容高度与比容高度之间的相关关系，利用2000—2010年太平洋区域的简单海洋数据集(SODA)计算出热、盐比容高度与比容高度，采用非线性典型相关分析法(NLCCA)，对热、盐比容高度与比容高度的相关性进行分析。研究发现：在太平洋区域，热比容高度对比容高度的季节及年际变化信号有显著影响，两者存在较强的线性关系，热比容高度主要影响赤道区域；盐比容高度则主要影响比容高度的长期变化趋势，对短周期的信号影响不显著；盐比容高度与比容高度之间的非线性关系较强，其影响区域主要集中在南太平洋。

To comprehend the relations between thermosteric height,halosteric height and steric height, the thermosteric height,the halosteric height and the steric height were obtained from Simple Ocean Data Assimilation dataset(SODA)from Jan 2000 to Dec 2010.The correlations between the thermosteric height, the halosteric height and the steric height were analyzed by the application of Nonlinear Canonical Correla-tion Analysis (NLCCA)method.The analysis shows that there is a strong linear relation between the thermosteric height and the steric height,of which the thermosteric height has an apparent impact on the seasonal and annual variation of steric height.Moreover,the maj or area of impact on steric height is loca-ted on the equator zone.The halosteric height,however,has a great influence on the long-term fluctuation and the correlation is nonlinear,with the maj or impact area located on the south Pacific.
