The new method is applied in an area bounded by 0.6 correlation coefficient contour to the point of 20°N, 118°E which is determined by EOF analysis. The results suggest that the method is suitable for indicating Kuroshio's intrusion into the South China Sea quantitatively. As an indicator, the Kuroshio penetrating the Luzon index (KLI) reveals obvious annual cycle and weak bi-modality. For annual periods, indexes on the surface and subsurface which point the same events have totally opposite signs due to the winter burst of surface westward current. On long-term period, the surface and subsurface indexes have consistent signs. A subsurface index on 150 m avoiding high frequency signals from the surface can be used for indicating long-term Kuroshio intrusion variation. An anti-phase pattern in wavelet coherence map between KLI and Japan large meander index shows that the Luzon Strait is a "smoother” reducing the variability of the Kuroshio transport changes on long-termperiods.
