Observation of Vortex Motion in Nature and Art
From ancient times to the present day vortex motion has fascinated mankind. There are innumerable cases of appearance，growth and disappearance of vortices in nature. Many designs of vortices have been used in art and life all over the world. In this paper various kinds of vortex motion in nature and art are presented. Observation of vortex motion of the ocean is studied by using multi-sensor remote sensing. The observation involves the effective use of three satellite remote sensing data of NOAA・AVHRR，MOS-1・MESSR，and LANDSAT・TM. The K?rm?n vortex street behind a circular cylinder observed in an open channel in a hydraulic laboratory is presented. A brief review of designs of vortex motion which appeared in Japanese traditional art and life is also presented.
