|
In order to clarify the impact of regional warming on the ozone concentration according to the differences in meteorological contribution in each city over the South-Eastern part of the Korean Peninsula, several numerical experiments were carried out. WRF - CMAQ model was used to access the ozone differences in each case, during the episode day. Meteorological contributions estimated by WRF command a reasonable feature on the dispersion of ozone concentrations in each city according to regional warming. This causes a difference in estimated ozone concentration. A higher ozone concentration difference tend to be forecasted in coastal cities than in upcountry city. Therefore, the emission reduction policy according to the regional warming should consider the characteristics of meteorological contribution of each city.
