Variation feature of the sensible heat flux and latent heat flux in South China sea

The heat exchange of ocean 2 atmosphere interface acts as an important role in the climatic variation,but it has an important influenced on the further research of the air-sea interaction because the observes data over ocean are sparse.In this paper the satellite data from SSM/I(Special Sensor Microwave/Imager) and AVHRR(Advanced Very High Resolution Radiomater) are used to estimate the sensible heat flux(SHF) and latent heat flux(LHF) on the air-sea interface over South China Sea(SCS) with the advanced COARE Bulk Flux Algorithm version 3.0a.Comparing with the in-situ observations in Xisha and Wenchang stations,the estimated results are very reasonable.It means that the satellite data can be taken as an efficient alternative for sparse observations over the ocean and it has important roles in the study of the air-sea interaction in SCS,and it becomes an important basis of the climate forecast and research in China as well.Moreover,it indicates that properties of the heat fluxes in SCS has notable seasonal,interannual and decadal variation period.The period of the sensible and latent heat fluxes is 0.5a,1a and quasi-3a and 6-11a,respectively.The interannual and decadal period of the heat fluxes in SCS is consistent with that of the dry and flood in China.So,it can be thought that interannual and decadal variation of the heat fluxes in SCS will play an important role that cannot underestimated on the dry and flood distribution in China.
