Description:
The Luzon Strait transport, as an index for the South China Sea throughflow, has
attracted much attention. In this study the interannual variability of the Luzon Strait
transport is examined, using the Island Rule and results from an ocean general
circulation model. Transport variability obtained from these two approaches are
consistent with each other. Assessment of contribution from each integral segment
involved in the Island Rule indicates that wind stress in the western and central
equatorial Pacific is the key factor regulating the interannual variability of the Luzon
Strait transport, whereas the effect of local wind stress in the vicinity of the Luzon
Strait is secondary. Analysis also shows that when the westerly (easterly) wind
anomalies in the tropical Pacific break out, the Luzon Strait transport increases
(decreases), consistent with the variations in the North Equatorial Current during El
Niño (La Niña) events.
