Based on the conjugate code technique, a mesoscale adjoint model is constructed, and the lateral boundary conditions of the model is discussed.

使用共轭码技术，构造了中尺度模式的伴随模式，研究了模式侧边界条件。

Emphasis is placed on the sensitivity analysis and the design of targeted observations based on the adjoint model. Some discussions and Suggestions are presented.

重点讨论基于伴随模式的敏感性分析与目标观测设计及其相关的一些问题。

The results indicate that the adding of conventional and non-conventional observations into adjoint model system can improve the quality of initial field, thereof improve the result of forecasting.

试验表明：在伴随模式同化系统中加入常规和非常规资料，可以改进初始场，从而改善预报场。
