| 摘 要： | 利用NASA高分辨率的卫星遥感资料SST,采用Nudging同化来模拟渤海、黄海、东海的三维温度场,减小用热通量作上边界条件所带来的误差.结果表明,模拟的海流场能较好地反映渤海、黄海、东海的环流特征.数据同化后的温度场优于未经同化的温度场.3个选择站点的同化值与实测值的均方根误差分别为1.307,0.526,0.744,用热通量资料模拟的水温与实测值的均方根误差分别为2.160,0.979,1.330.尽管只同化了海表温度,但数据同化对三维温度场结构都有影响.

| Abstract: | The nudging assimilation is used to simulate the three dimension temperature field of the Bohai Sea, the Huanghai Sea and the East China Sea to reduce the error of using heat flux as the upper boundary condition with the use of the high resolution satellite remote sensing data SST. The result shows that the simulated current field can reflect the circulation characteristics of the Bohai Sea, the Huanghai Sea and the East China Sea satisfactorily. The temperature field after data assimilation is better than that without data assimilation. The RMS between the assimilation data and the observed data of the three stations selected are 1.307,0.526,0.744 respectively, while the RMS between the temperature simulated by heat flux and the observed data are 2.160,0.979,1.330 respectively . Data assimilation effects the three dimensional temperature field although we only assimilate the sea surface temperature. |
