The remote of the sensible and latent heat fluxes in China coast

The heat exchange interfaced ocean and atmosphere acts an important role in the climatic variation, but it has influenced on further research of the air-sea interaction because the observations over ocean are sparse.In this paper the satellite data from SSM/I and AVHRR are applied to estimate the sensible flux and latent flux on the air-sea interface over China coastal sea (CCS) with the advanced method (COARE3.0).Comparison with the in-situ observations in Xisha and Wenchang stations, the estimated results are reasonable well.the root mean square (RMS) of sensible flux and latent flux are 2.9 and 29.9 W/m², respectively, contrasted with the observation data from Xisha Station in May 2002.The RMS of sensible flux are 4.42 W/m² (October 2000) and 4.19 W/m² (November 2000), the RMS of latent flux are 43.05 W/m² (October 2000) and 40.8 W/m² (November 2000) contrasted with Wenchang Station.The temporal and spatial distributions from this method are generally consistent with that of GSSTF2.Based on the analysis with the satellite data in CCS, the RMS is 11.7 W/m² for sensible flux and 43.2 W/m² for latent flux.It means that the sat ellite data could be taken as an efficient alternative for sparse observations over ocean and it has important role in the study of the air-sea interaction in CCS, as well it has been used as important basis on the climate forecast and research in China.
