摘　　要：气象信息的分析处理是以地图作为载体的,平面地图的局限性影响着气象信息的多尺度、多分辨率的集成管理,其结果导致了气象业务、气象研究、气象产品的割裂.文章分析了平面地图作为气象信息载体的局限性,提出了气象信息集成于数字地球所面临的3个基本问题:1)气象信息空间基准统一性;2)面向多尺度气象信息集成的地球椭球剖分技术;3)平面气象信息如何划算到椭球面.并对解决以上问题的技术途径进行了探讨.Geographic maps are the basis in weather information analysis. However,the limitations in 2D geograph- ic map, such as complexity and distortion in projection, lack in integration, all impose restrictions to the integrated management of multi-scale and multi-resolution meteorological information, which will result in the isolation between meteorological service, meteorological research and meteorological product. Three basic issues in integration of mete- orological information in digital earth are put forward, including unity of space benchmark, earth ellipsoid subdivi- sion for spherical integration of weather information, and theory ＆ algorithm for meteorological information transfor- mation from 2D to Earth ellipsoid. Technological approaches towards above issues are also discussed.
