Abstract. This paper presents six topics concerning vortex motions. Flow fields due to interactions of a vortex with either another vortex or a solid boundary are visualized by smoke. Some specific features are discussed with forms of smoke appearing during interaction process and with trajectories of vortices obtained indirectly from the successive photographs.
