Numerical Study of the Kuroshio Current in the Tokara Strait

Abstract

A high-resolution regional circulation model was configured over the southern coast of Japan including the Amami Oshima to simulate the Kuroshio Current through the Tokara Strait (TS). The results are in good comparison with the currentmeter data from the Acoustic Doppler Current Profiler (ADCP). Comparison experiment with a higher horizontal resolution suggests the Kuroshio current through the four-islands chain presents fine sub-mesoscale structures especially in the downstream. Also the sensitivity experiments suggest the main axis of the Kuroshio in the model with tides moves to the south slightly (offshore) at the eastern part of the TS. Furthermore, there is concentration of the stronger current (magnitude of current speed > 60 cm/s) to the upper layer. The vertical shear of the current becomes larger and the Kuroshio becomes more baroclinic due to the tidal effects.
