In this paper, the MM5 Adjoint Assimilation System is used to correct MM5's terrain error. The experimental results of amending different initial terrain data indicate that: the MM5 AAS is able to retrieve the terrain field, whose resolution is matched with one of the initial meteorological element field and therefore well coordinated with the MM5 model. Thus a new way about how to widely use the assimilation system is offered in this paper.

将伴随模式同化系统应用于修正模式地形误差，通过对不同初始地形的修正试验表明，MM5伴随模式同化系统能很好地对地形误差进行修正，能够反演出与初始气象要素场分辨率相匹配、与模式更协调的地形场，为伴随模式同化系统的广泛应用提供了一种新的思路。

从这个全离散问题出发，结合全局或局部已知的观测数据，分别构造梯度下降算法求解相应的最优化问题。我们分析了采用不同方法计算梯度所需的代价，另外，还给出一种选择最优迭代步长的算法。

Furthermore data assimilation experiments are conducted with MM5 Adjoint-model Assimilation System made by adjoint codes. With a case of heavy rainfall taking place from 00h July 23 to 00h July 24,2002, several numerical simulation experiments of different schemes are performed. The results are as follows. MM5 Adjoint-model Assimilation System not only can improve the initial field effectively and promote the coordination with the model but also can enhance the forecast on the precipitation and other elements. The assimilation of CDW has an improvement on quality of upper wind. The effect of direct numerical simulation with utilizing the CDW to amend the initial field gains the advantage over the one not.

结果表明，MM5伴随模式同化系统能有效改善初始场与模式的协调能力，提高模式对于降水场和其它要素场的预报；使用云导风资料修正初始场后直接模拟的效果比未使用时直接模拟的效果要好，对部分区域的强降水预报精度有一定程度的改善；使用伴随模式同化系统后，加入云导风资料的同化试验对其它要素的改善与直接同化常规资料的效果相比，改善优势不明显，但从各要素的误差来看，对于风场的改善最好。
