Abstract
본 연구에서는 AR5 RCP 기후변화 시나리오에 따른 우리나라 미래가뭄의 시공간적인 분포가 전망된다. 기후변화에 따른 영향을 보다 명확하게 살펴보기 위하여 인위적인 용수공급시스템이 갖춰져 있지 않은 지역을 대상으로 미래가뭄상황이 분석된다. 미래기후정보는 기상청에서 제공하고 있는 남한상세 1-km 해상도의 강수자료가 이용되며, 현재 대비 미래의 연평균 가뭄사상의 개수, 평균 가뭄지속 기간, 평균 가뭄심도가 비교된다. 연평균 미래 가뭄사상의 개수는 대부분 지역에서 현재의 수준을 유지하나, 연평균 미래 가뭄사상의 평균 지속기간 및 평균 가뭄심도는 대체적으로 중부지방에서 증가될 것으로 예측되었다. In this study, spatio-temporal behavior of future drought in South Korea under AR5 RCP climate change scenarios is projected. In order to investigate more explicitly the effect of climate change, future drought conditions for the region where artificial water supply systems are not well equipped are analyzed. Using South Korea-detailed 1-km resolution daily precipitation data provided by Korea Meteorological Administration as future climate information, annual mean numbers, mean drought event duration, and mean drought event severity of present and future drought events are compared, respectively. As a result, while the annual mean numbers of future drought events are not expected to be increased in most regions, the mean drought event duration and severity are predicted to be increased in the central region.
