Evidence suggests that when northern snow forced teleconnection is generated in this season, anomalous zonal/meridional circulations are revealed in east Asia-western Pacific band; with east Asia-Pacific teleconnection formed, anomalous zonal circulation is dominant over that band; the anomalous vortex of north Pacific origin moves southwestward and, r...

研究发现当北半球夏季出现积雪强迫型遥相关时，东亚－西太平洋地区既存在异常纬向环流，也存在异常经向环流；而当出现东亚太平洋型遥相关时，东亚－西太平洋地区以异常纬向环流为主。分析还发现源于北太平洋的异常涡旋在向南传播的过程中，先取西南路径，在到达菲律宾东部以后折向东南。
