It has been fon years since The South China Sea Monsoon Experiments (SCSMEX) in 1998. The South China sea air-sea flux experiments and the corresponding studies initiated by SCSMEX have been performed for ten years. Supported by SCSMEX and National Natural Science Foundation of China (40075003), three times of air-sea flux experiments (1998, 2000 and 2002) were conducted during the past ten years at Xisha Island respectively. The observational data were analyzed and examined with focus on the following aspects: air-sea interaction processes study during the period of pre-onset, onset, and developing stages of the SCS monsoon onset, the variation study on radiation fluxes, latent and sensible heat as well as momentum fluxes and their relationship with the synoptic conditions. The daily variation of air-sea fluxes, flux exchange coefficients and surface heat flux effects in the lower level of atmosphere and ocean surface were also included. This paper reviews the advances in the study of air-sea flux over the South China Sea. Moreover, some suggestions on future research, especially a new air-sea flux experiments plan in 2008 Asia monsoon year（AMY 2008）over the South China Sea are presented in this paper.
