| 英文摘要 | In this study, we investigated the features of arctic oscillation (ao) and antarctic oscillation (aao), that is, the annular modes in the extratropics, in the internal atmospheric variability attained through an ensemble of integrations by an atmospheric general circulation model (agcm) forced with the global observed ssts. 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. |
