This study investigates distribution of highly concentrated ozone generation for the last 5 years(2015~2019). To analyze the air flow and weather relation when highly concentrated ozone generated, the air current pattern was analyzed by using HYSPLIT model of National Center for Atmospheric Research, US. After HYSPLIT analysis, the characteristics of Case 1 ~ 4 were analyzed according to the travel distance. Case 3, 4 showed the most influence on generating highly concentrated ozone; it showed short travel distance. Also for Suncheon in Gwangyang-Bay area, the cause of considerable frequency and lasting time of YH and SD monitoring sites was analyzed. The total accumulated time of high ozone concentration 242 hours at YH site and 179 hours at SD site. The characteristics of the monitoring sites were analyzed by analyzing the correlation among ozone concentration, meteorological data and air pollutants. YH monitoring site showed the lowest wind speed and high correlation of Insolation. SD monitoring site showed considerably strong correlation of fine dust and ultrafine dust. Also the locations of the two sites are in leeward of the industrial complex area, therefore ozone can easily be generated and the wind speed is low, which can cause atmospheric congestion and generate highly concentrated ozone for a long time.
