利用NCEP/ NCAR再分析资料和其它资料（OLR、降水和温度）进行分析，结果表明，东亚和西北太平洋地区对流层环流和气候具有明显的准两年振荡（TBO）特征。研究还表明，东亚冬季风异常对次年夏季大气环流和气候变化有一定的影响，特别是东亚地区，东亚冬季风异常与ENSO循环之间存在明显的相互作用。东亚冬季风持续强（弱）可通过海气相互作用诱发厄尔尼诺（La Niña），厄尔尼诺（La Niña）事件可通过遥相关或遥相关响应导致东亚冬季风弱（强）。冬季风的强弱与ENSO循环相互联系。东亚冬季风异常与ENSO循环的相互作用是TBO的根本成因。
Based on the data analyses by using NCEP/ NCAR reanalysis data and other data (OLR, precipita-tion and temperature), it is shown that the tropospheric circulation and climate in East Asia and the northwestern Pacific region have the evident quasi-biennial oscillation (TBO) feature. It is also shown that anomalous East Asian winter monsoon can impact the atmospheric circulation and climate variations in the following summer, particularly in East Asian region; there is clear interaction between anomalous East Asian winter monsoon and ENSO cycle. The continuous strong (weak) East Asian winter monsoon can ex-cite El Niño (La Niña) through the air-sea interaction, the El Niño (La Niña) event can lead the East Asian winter monsoon to be weak (strong) through the teleconnections or remote responses. The strong or weak winter monsoon and ENSO cycle are linked each other. It can be suggested that interaction between anoma-lous East Asian winter monsoon and ENSO cycle is a fundamental origin of the TBO.
