摘要
利用小波分解、相关分析、解释方差及位相对比方法,分析讨论了近赤道海温与西太平洋副高在不同时间尺度上的结构特征与对应关系。分析表明,不同海域海温变化与副高活动的幅值和位相存在明显的多尺度特征和强度差异,不同海域的海温热力作用分别在不同的时间尺度上显著影响和制约西太平洋副高活动。
Methods of wavelet decomposition, correlation analysis, analytic variance and phase contrast were used to discuss the structural features of and relationship between near-equatorial SST and the west Pacific subtropical high. The study shows that large differences exist in different parts of the ocean in the multi-scale characteristics and intensity of the amplitude and phase as far as the SST change and subtropical high activity are concerned. From different parts of the ocean and different time scales, SST thermodynamics significantly affects and restrains the west Pacific subtropical high.
