Abstract

Abstract

Conductivity-temperature-depth data from four cruises spanning 2009 to 2012 are used to investigate the structure of the upper layer circulation in the middle and southern South China Sea(SCS) during the monsoon transition. In the late spring,2009,the upper structures of the middle and southern SCS have begun to take the summer circulation structure and the Southeast Vietnam Offshore Current(SVOC) has been evident. In November 2010,the dynamic heights in the middle and southern SCS show that the upper structures of the middle and southern SCS have converted to the winter pattern. In this period,the SVOC has been vanished and the Natuna Off-Shelf Current(NOC) has been evident. In October 2011,the structures of the SCS were converting to the winter pattern from the summer characterized by the reductions of the SVOC,but the anticyclonic circulation in the summer pattern still existed. In September 2012,the upper structures of the middle and southern SCS have been similar to the summer pattern mainly be seen in the existed of the SVOC and the structures of the circulation were the same as the summer pattern on either sides of the SVOC. In addition,the analysis results also clearly shows the changing of the circulation of the middle and southern SCS from summer to winter.
