Abstract
This paper discusses the occurrences of von Karman vortices in the lee of Cheju Island. In this area an isolated mountain often disturbs airflow over the Korea South Sea. The vortex street often occurs with a strong northerly flow with persistent patterns of cumulus and stratiform clouds. The generation of vortices and cloud streaks including enhancement of precipitation in the lee side observed with NOAA satellites are discussed in this paper. Observations of vortex and cloud formation by the Halla Mountain up to 800 km are recorded. Ten cases shown here are classic examples of lee disturbances in meso‐ and synoptic‐scales which are of interest for atmospheric dynamics research and tutorial aid.
