Multiple oceanic eddies coexist in the North Pacific subtropical front zone (STFZ) in winter, which can be classified into the isolated single eddies, the combined double isotropic eddies and pairs of anisotropic eddies. The forcings of these eddies on the mid-latitude atmosphere are investigated using Climate Forecast System Reanalysis (CFSR) data from year 1979 to 2009, which are divided into the remote and local effects in this research. In the years with a stronger subtropical front, there are more cyclonic isolated and double eddies to the north, more anticyclonic isolated and double eddies to the south of the STFZ, and more eddy pairs with cold to the north and warm to the south concentrated around the main axis of the STFZ. These eddy distributions enhance the strength of the subtropical front, intensify the propagation of upwards baroclinic waves in the lower atmosphere, and finally enhance the zonal wind at upper atmosphere, which is defined as the remote effects of the eddies. However, distinct from this basin-scale remote forcings, three types of oceanic eddies also have different local forcings on the marine atmospheric boundary layer (MABL) above and on the middle atmosphere as expressed in local precipitation difference. The local effects of the isolated single eddies and combined double isotropic eddies take place near the eddy center, whereas that of the pairs of anisotropic eddies at the boundary of the two eddies.

冬季，北太平洋副热带锋区（STFZ）多个大洋涡旋并存，可分为孤立的单涡、组合双各向同性涡和成对的各向异性涡。使用1979年至2009年的气候预报系统再分析（CFSR）数据研究了这些涡流对中纬度大气的强迫，本研究将其分为远程和局地效应。在副热带锋较强的年份，北面气旋孤立双涡较多，STFZ南面反气旋孤立双涡较多，北冷暖南涡对集中在附近STFZ 的主轴。这些涡旋分布增强了副热带锋的强度，加强了低层大气向上斜压波的传播，最终增强了高层大气的纬向风，这被定义为涡流的远程效应。然而，与这种盆地尺度的远程强迫不同，三种类型的海洋涡旋对海洋大气边界层（MABL）上方和中层大气也有不同的局地强迫，表现为局地降水差异。孤立的单涡和组合双各向同性涡的局部效应发生在涡中心附近，而成对的各向异性涡的局部效应发生在两个涡的边界处。三种类型的海洋涡旋对上方海洋大气边界层（MABL）和中层大气也具有不同的局地强迫，表现为局地降水差异。孤立的单涡和组合双各向同性涡的局部效应发生在涡中心附近，而成对的各向异性涡的局部效应发生在两个涡的边界处。三种类型的海洋涡旋对上方海洋大气边界层（MABL）和中层大气也具有不同的局地强迫，表现为局地降水差异。孤立的单涡和组合双各向同性涡的局部效应发生在涡中心附近，而成对的各向异性涡的局部效应发生在两个涡的边界处。
