English 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.
