1997 ~ 1998年期间，利用安装在日本和澳大利亚之间的志愿观测船（VOS）船体上的ADCP对西北太平洋副热带环流进行了多次观测。黑潮、黑潮环流和北赤道流是10-34.5° N纬度带的两年平均流。在10-30° N带，海流变率主要由斜压Rossby波或中尺度涡旋控制，但在13-17° N纬度带，北赤道海流流轴的南北移动可能主导海流变率。中尺度变率的能量集中在18.5°N和23°N附近形成大的峰值。
During 1997 to 1998, near‐surface currents in the western North Pacific subtropical gyre have been measured repeatedly by an ADCP mounted on the hull of the volunteer observing ship (VOS) operated mainly between Japan and Australia. The Kuroshio Current, the Kuroshio Recirculation and the North Equatorial Current are clearly identified as two‐year mean currents in the latitude belt 10–34.5° N. Current variability was dominated by baroclinic Rossby waves or mesoscale eddies over the 10–30° N belt except in the latitude belt 13–17° N where the north‐to‐south shifts of the North Equatorial Current stream axis may dominate current variability. The energy of the mesoscale variability was concentrated to form large peaks around 18.5°N and 23°N.
