| Abstract: | The previous studies show that the spreading path of the subtropical salinity minimum of the North Pacific Intermediate Water (NPIW) is southwestward pointing to the Luzon Strait.Based on the P-vector method and generalized digital environmental model (GDEM) data,the volume transport of NPIW through Luzon Strait and the upward transport on the NPIW lower and upper boundaries are calculated to examine the destiny of NPIW in the South China Sea (SCS).On the annual mean,the estimation of NPIW transport into the SCS through the Luzon Strait is 1.72 Sv (1Sv=106m3/s).The upward transport over the SCS is 0.31 Sv on the NPIW upper boundary and 1.31 Sv on the NPIW lower boundary.There is no strait or passage deeper than the surface for the NPIW to extend,except for the Luzon Strait.For the volume balance in the SCS NPIW,the volume transport of 2.72 Sv has to flow out of the SCS NPIW layer through the Luzon Strait. |
