For this purpose, we selected urban areas in the Honam Jeongmaek in Korea and analyzed the nighttime cold airflow and altitude of the cold air layer generated in mountains, by using the KALM (Kaltluftabflussmodell) model which calculates the amount of cold air generated during the nighttime without winds. The results of analysis found that the local airflows generated in Mt. Chuwol, Mt. Mudeung, Mt. Cheonun, Mt. Byeongpung and Mt. Geum influenced the entire study site from across Gwangju Metropolitan City to adjacent areas.
