The Karman votexes under the lee side of Cheju Island

Abstract

On the 27th February 1984, a weather satelite took a beautiful photograph of the Karman votexes under the lee side of Cheju Island. We surveyed geographical features of the island and meteological data of the day. The hydrodynamic conditions of the occurence of votexes were examined and also compared with the surveyed results. The Karman votexes possibly occured hourly on the one side when the wind of velocity 18∼22m/s blew from NNW to the island higher than 1,000m above the sea level.
