| 摘 要： | 本文利用浅水方程模式，对变分四维同化过程中模式中误差的影响进行了数值模拟实验，实验显示了模式误差被“混淆”入初始场的现象，在一些模式变量无观测时，这种混淆的后果更为严重。

| Abstract: | Some numerical experiments are performed on a shallow water equation model to investigate the effect of model errors on variational four-dimensional assimilation. It is showed that the errors in the model are aliased to the initial fields. This aliasing is particularly serious in the case of without the observation of some model variables. |
