摘　　要：作为连接观测数据和数值模型的桥梁,数据同化在大气、海洋、石油等领域具有相当重要的作用。数据同化课程涉及算法众多,理论讲解过程非常繁琐。该文基于Lorenz-96数学模型,设计和实现了数据同化课程基础算法数值实验系统,并基于Matlab GUI实现了算法的参数输入、界面设计和结果绘图。该实验系统模块清晰,操作简单,内容覆盖范围广,既可为教师讲解基础算法提供可视化载体,又可为学生提供算法实验平台,有助于提升课堂教学质量、加深学生对算法的理解和提高学生的动手能力。As a bridge between observed data and numerical models,data assimilation plays an important role in various fields such as atmosphere,ocean and petroleum.The course of data assimilation involves many algorithms,and the process of theoretical explanation is very complicated.In this paper,the data assimilation numerical experiment system has been designed and implemented on the basis of the Lorenz-96 model.By using Matlab GUI tool,many functionalities of the system have been listed by involving parameter input of the algorithm,interface operation and result drawing.The experiment system has the advantages of clear modularized process,simplification and wide coverage.It can be used not only as a carrier for teachers for algorithm visualization demo in classroom teaching,but also as a platform for the students’actual operation in the experimental course.The system can help to improve the teaching quality,strengthen the students’practical ability and deepen their understanding of the data assimilation algorithms.
