A Regional Climate Change Simulation over East Asia
Dong-Kyou Lee,차동현,진천실,Suk-Jin Choi 한국기상학회 2013 Asia-Pacific Journal of Atmospheric Sciences Vol.49 No.5
In this study, regional climate changes for seventy years (1980-2049) over East Asia and the Korean Peninsula are investigated using the Special Reports on Emission Scenarios (SRES) B1 scenario via a high-resolution regional climate model, and the impact of global warming on extreme climate events over the study area is investigated. According to future climate predictions for East Asia, the annual mean surface air temperature increases by 1.8oC and precipitation decreases by 0.2 mm day−1 (2030-2049). The maximum wind intensity of tropical cyclones increases in the high wind categories,and the intra-seasonal variation of tropical cyclone occurrence changes in the western North Pacific. The predicted increase in surface air temperature results from increased longwave radiations at the surface. The predicted decrease in precipitation is caused primarily by northward shift of the monsoon rain-band due to the intensified subtropical high. In the nested higher-resolution (20 km) simulation over the Korean Peninsula, annual mean surface air temperature increases by 1.5oC and annual mean precipitation decreases by 0.2mm day−1. Future surface air temperature over the Korean Peninsula increases in all seasons due to surface temperature warming, which leads to changes in the length of the four seasons. Future total precipitation over the Korean Peninsula is decreased, but the intensity and occurrence of heavy precipitation events increases. The regional climate changes information from this study can be used as a fruitful reference in climate change studies over East Asia and the Korean peninsula.

원전사고 발생 시 방사성물질의 누출에 따른 주민보호조치 전략 수립을 위한 기반연구로 원전부지 바람의 발생 특성을 분석하였다. 국내 5개 원전부지(한빛;한울;월성;고리;신고리)의 최대 10년의 장기간 관측자료를 이용한 풍향⋅풍속 및 해륙풍 분석을 통해 각 부지에서의 방사성물질 이류⋅확산 방향 및 속도와 관련된 기류 특성과 방사성물질의 축적을 초래하는 무풍 발생 특성을 분석하였다. 각 부지별 바람은 계절⋅시간별로 다른 발생 특성을 보이므로;세분화된 시간 규모로 작성된 기류분석 데이터베이스가 필요하며;계속된 업데이트를 통해 만일의 사고에 대비한 방재훈련 및 대책마련의 객관적인 참고자료로 활용할 수 있을 것이다. To establish a strategy for public protective action from radioactive leakage in the event of Nuclear Power Plant (NPP) accidents;long-term records of wind data collected at the Korean NPPs were analyzed. Wind characteristics related to the advection and diffusion of radioactive pollutants were examined by analyzing the wind direction;speed;and land-sea breezes for NPPs (Hanbit;Hanul;Wolsong;Kori;and Shin-Kori) in Korea. The study also analyzed the characteristics of calm winds causing the accumulation of radioactive materials. The wind characteristics of each NPP differ depending on the seasonal and daily variabilities; thus;a detailed time-scaled airflow database is required. In addition;the findings;through continuous updates of the airflow database;will contribute to improving preparedness.
