[1] In this paper, the trend of upper-layer circulation in the South China Sea (SCS) is studied based on the Simple Ocean Data Assimilation product for 1959–2008. It is found that the basin-averaged SST in winter displays a warming rate close to the global mean value while it does not have significant trend in summer. The upper-layer circulation in the SCS has been weakened in winter by 10% over this period, while in summer it tends to be more energetic. Further analyses suggest that the weakening of the winter SCS ocean circulation in winter is associated with weakening of the East Asian monsoon over recent decades. Moreover, an eastward retreat of the anti-cyclonic “Kuroshio loop” from the SCS is found, which may be due to an intensification of the Kuroshio transport in the past 50 years.
