| Research Abstract |
Sensitivity analyses and an ocean reanalysis experiment are conducted using an ocean data assimilation system to clarify the long-term variability of the Kuroshio large meander. The sensitivity analyses revel that the lower Kuroshio transport leads to the longer duration of the large meander, indicating that the duration of the Kuroshio large meander strongly depends on the Kuroshio transport. It is also shown that the log history of the Kuroshio large meander is explained by considering the Kuroshio transport, Kuroshio extension state, and mesoscale eddy activity east of Taiwan.
