AbstractThe persistent meteor train is observed in various forms. It is considered that thesecharacters are caused by the tube structure of the meteor train, the turbulence along the tubesurface, and the convection in the upper atmosphere. However, because of the upper atmosphericwind effects and the dissipation process of the meteoric plasma, the structure begins to disappearas soon as it appears. In Leonids shower 2001, a lot of images of the meteor train were reportedto the METRO (meteor train observation) campaign in Japan: the 242 cases of 134 examples.We tried to obtain high-resolution images of the meteor train using fast-exposure photograph andvideo observation with telephoto lenses, particularly those of 200 mm or longer focal length. Manytrain images which indicated some interesting fine structures were successfully obtained by theMETRO campaign during 1998-2001. In this paper, the morphology of the persistent meteor trainjust after its appearance is discussed.
