摘　　要：随着空间信息科学的发展,人们能够基于丰富的地理信息进行专业数据更加直观的可视化表达,为专业领域的研究提供支持。深入分析Keyhole标记语言KML(Keyhole Markup Language)对地理数据表达的逻辑结构,结合气象数据的空间特性,提出基于KML的气象数据表达模型架构体系。基于程序语言设计完成具备多层次结构的相关类库,实现了气象数据的KML多维度集成表达,以期为气象领域的专业研究提供新的可视化平台。With the development of geosciences, professional data can be represented with better intuitive visualisation based on the abundant geo-information, and this supports the researches in professional fields. We thoroughly analysed the logical structure of KML on geographic data representation, and put forward the KML-based architecture of meteorological data expression model in combination with the spatial characteristics of meteorological data. Furthermore, based on program language design we completed the correlated class library with multi-layer structure, thus realised the integrated multidimensional representation of meteorological data, in order to provide the new visual platform for professional researches in meteorological field.
