在亚太摆动(APO ) 和在在夏日(JuneAugust ) 期间和平的北方的海表面温度(SST ) 之间的连接 preliminarily 通过观察数据的分析被调查。APO 显著地并且断然被相关到北方太平洋 SST,这被发现,与是的关联系数 0.58 在 interannual timescale 上在时期期间 19542003,它建议那一强壮(弱) APO 对应于高度(低) 在北方太平洋的 SST。他们的同相的关系被动态、热的条件很好与 APO 异例联合支持。当 APO 在积极阶段时,在上面的对流层的东方亚洲西的喷气被削弱,并且异常逆旋风的发行量占优势在在北方太平洋上低对流层。而且,理智、潜伏的热流动的否定异例在北方太平洋被支配,显示海洋得到从空气的热流动。同时,温暖的水移流向北方在北方太平洋被加强。所有这些提供有益的条件温暖北方太平洋 SST,并且因此, SST 在这个区域被增加,并且反过来也如此。
The linkage between the Asian-Pacific Oscillation (APO) and the sea surface temperature (SST) in the North Pacific during the summertime (June-August) is preliminarily investigated through an analysis of observed data. It is found that APO is significantly and positively correlated to the North Pacific SST, with the correlation coefficient being 0.58 on the interannual timescale during the period 1954~2003, which suggests that a strong (weak) APO corresponds to high (low) SST in the North Pacific. Their in-phase relationship is well supported by the dynamic and thermal conditions in association with the APO anomaly. When APO is in the positive phase, the East Asian westerly jet in the upper troposphere is weakened, and the anomalous anticyclonic circula- tion prevails in the low-troposphere over the North Pacific. Besides, the negative anomaly of the sensible and latent heat fluxes is predominated in the North Pacific, indicating ocean gets heat flux from the atmosphere. Meanwhile, warm water advection northward is strengthened in the North Pacific. All of these provide beneficial conditions to warm the North Pacific SST, and thus the SST is increased in this region, and vice versa.
