Abstract

Abstract:

Using the simple ocean data assimilation (SODA) data from 1967 to 2001, this study revealed the upper level salin-ity distribution in the South China Sea (SCS) and its response to the activity and intensity of the SCS monsoon. The results indicate that with the onset of the SCS monsoon, the high-salinity tongue in the northern and southern SCS weaken and retreat eastward, the salinity decreases in the northern and eastern SCS but increases in the southern SCS. In the strong monsoon years, the anomalous salinity is negative in the coastal sea area and the eastern SCS, but negative in the southern SCS. In the weak monsoon years, the anomalous pattern of salinity is the opposite. The upper level salinity’s response to the activity and intensity of the SCS monsoon in the SCS is closely related to the net freshwater flux, wind stress, and Ekman pumping.
