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.

In order to clarify the impact of regional warming on the meteorological field and air quality over southeastern part of Korean Peninsula, several numerical experiment were carried out. Numerical models used in this study are WRF for the estimate the meteorological elements and CMAQ for assessment of ozone concentration. According to the global warming impact, initial air temperature were changed and its warming rate reach at 2 degree which was based on the global warming scenarios provided by IPCC. The experiments considering the global warming at initial stage were presented as case T_UP. Air temperature over inland area during night time for case T_UP is higher than that for Base case. During time since the higher temperature over inland area is maintained during daytime more intensified sea breeze should be induced and also decrease the air temperature in vicinity of coast area. In case of T_UP, high level concentrations ozone distribution area was narrowed and their disappearance were faster after 1800LST. As a results, wind and temperature fields due to the global warming at initial stage mainly results in the pattern of ozone concentration and its temporal variation at South-Eastern Part of the Korean Peninsula.

장래 의 증가에 따른 지구 기온의 상승은 그 정도의 차이는 있으나 불가피한 것으로 예측되고 있으며, 강수량의 경우는 대기대순환모형(General Circulation Model, GeM)의 종류에 따라 감소에서 증가까지 다양한 결과를 보이고 있다. 특히, 강수량의 변화는 평균적인 개념의 연평균, 계절평균이나 월 평균도 중요하지만 국가적인 재해와 관련된 홍수나 가뭄의 발생도 중요한 관심사항이 된다. 홍수나 가뭄의 발생변화를 적절히 예측하기 위해서는 기술적
