中尺度数值模式的资料同化系统——(二)伴随模式系统的检验与试验

DATA ASSIMILATION SYSTEM FOR MESOSCALE MODELS PARTⅡ:VERIFICATION AND EXPERIMENTAL RESEARCH

在《中尺度数值模式的资料同化系统——（一）伴随模式的设计》一文的基础上，进一步对伴随模式码的检验问题做了讨论。表明采用共轭码方法是可行的。其导出的伴随模式与理论推导的共轭方程是相容的。试验发现该同化系统有消除随机干扰的能力，同化效果好。在同化过程中，系统是先同化大尺度信息，然后逐步同化中小尺度信息。

On the basis of the companion paper Part Ⅰ:Layout of an Adjoint Model, study is undertaken of the verification of the adjoint model code, indicating that the conjugate code method is effective enough that the derived adjoint model is compatible with the theoretical conjugate equation. Experimental evidence shows that the assimilation scheme is able to remove stochastic interference, yielding good results. The assimilation is such that the study system deals with the assimilation of large scale information and thereafter of meso and small scale message.
