摘要	An ensemble-based method for the observation system simulation experiment(OSSE) is employed to design optimal observation stations and assess the present observation stations in the northeastern South China Sea(SCS).We employed the 20-year(1992-2012) sea surface height(SSH) data to design an array to monitor the intraseasonal to interannual variability.The results show that the most key region was found located at the northwest of Luzon Island(LI) where the energetic Luzon cyclonic gyre(LCG) occurs;other key regions include the edge of the LCG,the northwest of the Luzon Strait(L S),and the southwest of Taiwan,China.By contrast,we found that the present observation stations might oversample at the northwest of the LS and undersample at the northwest of LI.In addition,the optimal stations perform better in a larger area than the present stations.In vertical direction,the key layer is located within the upper200-m depth of which the surface and subsurface layers are most valuable to the observing system.
