| Research Abstract |
In this study, we investigate the cause of the complexity and the diversity of the aurora, which is mysterious due to its wavy structures and its quick motion. We statistically compare the two drift velocities of the auroral fine structures, deduced from the electron data and auroral image observed by Reimei satellite. Then it can be possible to discuss the time evolution of the electric field structures in the acceleration region, using the observed drift velocity ratio and the time variation of the auroral images.
