Description:
Analysis based on the “Island Rule” and ocean assimilation dataset shows that the interannual variability
of the Indonesian Throughflow and the Luzon Strait (South China Sea) Throughflow is out of phase. Wind anomaly
in the equatorial Pacific plays an important role in setting up this phase relation. During El Niño events, the westerly
wind bursts intensify the Northern Equator Current and induce a northward shift of its bifurcation point. As a result,
the partition of volume transport between the Kuroshio and the Mindanao Current is changed, with the Kuroshio
transport decreased and the Mindanao Current increased. The undershooting/overshooting phenomena occur at the
Luzon Strait and the Sulawesi-Mindanao passage, caused by variability of these two currents. Water transport from
the Pacific to the South China Sea increases with the Kuroshio transport decreased, and transport from the Pacific to
the Indian Ocean decreases with the Mindanao Current transport increased. Therefore, the interannual variability of
the Indonesian Throughflow and the Luzon Strait Throughflow is out of phase.
