| 摘 要： | 基于西太平洋副热带高压的异常活动与亚洲夏季风系统其他成员之间存在着密切联系的天气事实,运用交叉小波的非线性时滞相关分析方法,对东亚夏季风系统成员与西太平洋副热带高压形态和变异的相互影响的基本事实和物理特征进行研究,得到了西太平洋副热带高压与主要的亚洲夏季风系统成员之间基本的关联结构和演变示意图。研究结果揭示了不同的季风子系统对西太平洋副热带高压的影响不同:影响西太平洋副热带高压强度和脊线位置异常变化的是亚洲夏季风系统中的印度夏季风子系统的5个主要成员;而影响西太平洋副热带高压西脊点异常变化的则是亚洲夏季风系统中的另一个子系统——东亚夏季风子系统的5个主要成员。研究揭示了副热带高压与亚洲夏季风系统主要成员之间的时延特征与统计关联特性,为相应的机理研究提供了事实依据。 |

| Abstract: | The abnormal activities of the western Pacific subtropical high(WPSH) are closely associated with other members of the Asian summer monsoon(ASM) system.By using the time-delayed correlation analysis method, the basic fact and physical characteristics how key members of the ASM system influence on the morphology and variation of WPSH are analyzed.And figures of the basic association structure and evolution are drawn.Results show that different subsystems of ASM system play different roles on WPSH:the abnormal intensity and position of WPSH are influenced by five key members of the Indian summer monsoon subsystem, while the abnormal west ridge point of WPSH is mainly caused by the five members of the East Asian summer monsoon subsystem.The results reveal the time-delayed characteristics and statistical correlation between WPSH and the key members of ASM system, which supply the basic fact for the future mechanism study. |
| Keywords: | western Pacific subtropical high (WPSH) Asian summer monsoon system cross wavelet transform time-delayed correlation |
