摘要

在这研究,我们调查了北极摆动( AO )和南极摆动( AAO )的特征,也就是说在额外的热带的环形的模式,在与全球观察 SST 强迫的一个大气的总环流大气环流模型( AGCM )通过集成的一个整体达到的内部大气的可变性。我们集中于内部 AO/AAO 的年度可变性,它被内部大气的可变性统治。与以前的观察结果比较,在内部大气的可变性的 AO/AAO 忍受一些类似的特征,但是展出清楚得多的空间结构:在北方太平洋和诺思大西洋之间的重要关联行动,强壮得多、更重要的联系降水异例,和 upper-tropospheric 的南方的排水量集中在北 / 南部的半球的西的急流。另外,我们检验了在诺思大西洋摆动(NAO )/AO 和东方亚洲冬季季风(EAWM ) 之间的关系。在内部大气的可变性, EAWM 变化是,这被显示出显著地与通过 upper-tropospheric 的 NAO 有关大气的电视连接模式。

We focused on the interannual variability of AO/AAO, which is dominated by internal atmospheric variability. In comparison with previous observed results, the AO/AAO in internal atmospheric variability bear some similar characteristics, but exhibit a much clearer spatial structure: significant correlation between the North Pacific and North Atlantic centers of action, much stronger and more significant associated precipitation anomalies, and the meridional displacement of upper-tropospheric westerly jet streams in the Northern/Southern Hemisphere.In addition, we examined the relationship between the North Atlantic Oscillation (NAO)/AO and East Asian winter monsoon (EAWM). It has been shown that in the internal atmospheric variability, the EAWM variation is significantly related to the NAO through upper-tropospheric atmospheric teleconnection patterns.
