摘要
Abstract
已有研究表明:厄尔尼诺-南方涛动(ENSO)与热带平流层准两年振荡(QBO)对北半球冬季平流层环流的协同影响主要表现为ENSO信号和QBO信号的线性叠加.本文进一步探讨ENSO-QBO联合强迫对大气环流总异常的非线性分量和线性分量相对贡献.结果表明,ENSO-QBO对平流层的协同影响几乎是ENSO信号和QBO信号的线性叠加,即表现出强线性叠加关系.从平流层到对流层,线性解释分量有所减弱.ENSO-QBO对对流层协同影响的线性与非线性分量表现出 一定的空间非均匀性:线性分量在低纬至中纬地区依然较强.在高纬地区非线性分量很快主导了总环流异常;此外,对流层ENSO信号远强于QBO信号,尤其是在厄尔尼诺—QBO东风位相情况下.关键词
