| 摘 要： | 对计算海-气界面湍流热通量的Bulk算法的一些参数进行了改进。使用西沙实测资料、GSSTF2资料和NCEP/NCAR再分析资料以及改进后的算法,计算了中国近海地区的感热通量、潜热通量。计算结果与西沙实测资料、长年代的GSSTF2资料和NCEP/NCAR再分析资料进行比较验证,证明改进后的方法精度较高,基本可以保证湍流热通量的平均标准偏差在10W/m2左右,与多年的月平均做比较,相对偏差为25%左右;同时,不仅首次将计算热通量的空间尺度精确到0·1°×0·1°,而且基本模拟出了南海季风暴发期间热通量变化的主要特点以及中国近海热通量随季节、纬度和海岸地形的变化特征。 |

| Abstract: | Using data sets of GSSTF2, NCEP/NCAR reanalysis and observational ones in Xisha Archipelago, the South China Sea, we calculated the turbulent heat fluxes at the air-sea interface in maritime China with commonly used bulk method with improvement on some parameters. With the modified method, sensible and latent heat fluxes in the areas were simulated. Comparison of the simulated results with the observational data in Xisha, the reanalysis data, and the satellites data showed that the improvement of the bulk method in accuracy is clear. The modified method can satisfy the limit of mean square deviation within 10W/m2, and the average relative error is about 25%. In addition, for the first time, the new method enhanced spatial resolution to 0.1°×0.1° in turbulent heat fluxes. The results are able to simulate the main features of variation in sensible and latent heat fluxes in different seasons, latitudes, and terra ins in marginal seas of China, and also to reflect the general pattern of heat flux changes during summer monsoon outbreak in the South China Sea. |
