本文运用了南海观测资料去评估五个海表热通量格点资料,同时,也计算了这五种格点资料的海表热收支平衡。结果发现这些格点资料都低估了短波辐射和感热通量,但是潜热通量除了NOC2外都相对接近观测值。低估了短波辐射也表明了这些格点资料可能低估了海表热收支。五种格点资料的净热通量都是正值,表明海洋从大气中获得热量。综合比较来看的话,NOC1资料所得的海表热通量收支可能更接近于观测值,更合理。 In this paper, we use the South China Sea observation data to evaluate the data of five sea surface heat fluxes and calculate the balance of the sea surface heat budget of the five grid data. The results show that these grid data underestimate the shortwave radiation and the sensible heat flux, but the latent heat fluxes are relatively close to the observed values ​​except NOC2. The underestimation of shortwave radiation also shows that these grid data may underestimate the thermal balance of the sea surface. The net heat flux for the five grid data is positive, indicating that the ocean receives heat from the atmosphere. A comprehensive comparison of the words, NOC1 data derived from the surface heat flux may be closer to the observations and more reasonable.
