Abstract: To increase flight safety and flight experience under special weather phenomena, the diversity and typical cases of special weather conditions should be considered in flight simulation training, the dynamic and successive meteorological data should be studied, and the insufficient of meteorological services should be overcome by comparing with the traditional flight simulator. The meteorological service with the generation model of multiple size of template library for typical special weather, the dynamical deduction model of meteorological data, and the interpolation calculation model of meteorological grid-point data were proposed. The meteorological service federate based on High Level Architecture (HLA) was established. FOM/SOM templates were built, and the unit flowchart was given. The more realistic special weather phenomena for flight simulation training system can be provided by the service.

Key words: HLA, data interpolation of meteorological lattice, meteorological service, dynamic deduction of meteorological data
