| 摘 要： | 应用由卫星SSM/I(Special Sensor Microwave/Imager)和AVHRR(Advanced Very High Resolution Radiometer)遥感资料,使用先进的海气通量计算方法(TAGA COARE3.0),计算出南海1987年7月至2004年12月共200个月的海气界面的感热和潜热通量(0.25°×0.25°),其结果与实测结果比较发现,由卫星反演的海气热通量与实测结果非常一致.与GSSTF2的结果相比,其时空分布变化特征基本一致.由此说明,利用卫星遥感获得的热通量可以用来进行中国近海海气相互作用的研究以及作为我国气候预测研究的重要依据.由多年南海海气热通量的分析表明,南海区域热通量的变化具有显著的年变化和年际变化特征,其周期分别是0.5a、1a、准3a和6～11a.其中准3a和6～11a周期与中国旱涝的周期一致.因此,可以认为南海区域热通量的年际变化对中国的旱涝分布将起着不可低估的作用.

| Abstract: | The heat exchange of ocean-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 quasi3a 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. |
