| 摘 要： | The CTD (conductivity, temperature and depth) data collected by six China-Korea joint cruises during 1996-1998 and the climatological data suggest that the seasonal variability of average salinity in the Yellow Sea (Sa) presents a general sinusoid pattern. To study the mechanism of the variability, annual cycles of Sa were simulated and a theoretical analysis based on the governing equations was reported.Three main factors are responsible for the variability: the Yellow Sea Warm Current (YSWC), the Changji-ang (Yangtze) River diluted water (YRDW) and the evaporation minus precipitation (E-P). From December to the next May, the variability of Sa is mainly controlled by the salt transportation of the YSWC. But in early July, the YSWC is overtaken and replaced by the YRDW which then becomes the most important controller in summer. From late September to November, the E-P gradually took the lead. The mass exchange north of the 37癗 line is not significant.

| Abstract: | The CTD (conductivity, temperature and depth) data collected by six China-Korea joint cruises during 1996–1998 and the climatological
data suggest that the seasonal variability of average salinity in the Yellow Sea (Sa) presents a general sinusoid pattern. To study the mechanism of the variability, annual cycles ofSa were simulated and a theoretical analysis based on the governing equations was reported.
Three main factors are responsible for the variability: the Yellow Sea Warm Current (YSWC), the Changjiang (Yangtze) River
diluted water (YRDW) and the evaporation minus precipitation (E-P). From December to the next May, the variability ofSa is mainly controlled by the salt transportation of the YSWC. But in early July, the YSWC is overtaken and replaced by the
YRDW which then becomes the most important controller in summer. From late September to November, the E-P gradually took the
lead. The mass exchange north of the 37°N line is not significant.
