摘要: 利用《2000年南海海气通量观测》外场观测资料对海气通量计算模式进行了敏感性试验。试验分析结果表明:感热通量对观测要素的观测误差比较敏感,因而其计算结果的误差较大;相反,潜热通量和动量通量对观测要素的观测误差相对不太敏感,因此,它们的计算结果比较可靠。试验结果也证实了表面通量计算的合理性,其结论可用于对实测资料进行误差检测。

Abstract: In this article, the sensitivity test of air-sea surface flux model was carried out by the field observation data of " South China Sea Air-Sea Flux Measurement During 2000" project. The results show: sensible heat flux are sensitive to observation error, so the error of model calculation is great; In contrast, latent heat flux and momentum flux is not so sensitive to observation error as sensible heat, and their calculated results is reliable. The test result also verifies the reasonable value of surface flux calculation, the conclusion can detect error in observed data.
