Urbanization Effect on the Observed Warming in Korea during
the Recent Half Century

Department of Ecosystem Management and Engineering, Kyung Hee University, Suwon 449-701, Korea

(Received January 10, 2002; Accepted February 27, 2002)

ABSTRACT
Since the rapid urbanization period coincides with the start of global warming, climate data might be contaminated with urbanization effect in Korea. Monthly normals of daily minimum, maximum, and mean temperature of 14 stations were calculated for 1951-1980 and 1971-2000 periods. Differences in two temperature normals were regressed to the natural logarithms of population increase at corresponding 14 cities from 1966 to 1990. The regression models were used to remove potential effects of urbanization from the apparent warming, and to determine the net contribution of global warming to the temperature change in Korea during the recent half century. According to the model calculation, there was little evidence of global warming in the warm season (May through November), while urbanization effect was common in all season except April. Up to 0.5 warming of nighttime temperature was found to be induced by urbanization. Cool season temperature was increased by up to 0.6 due mainly to the global warming of daytime temperature.

적요

1951-1980 평년기온 대비 1971-2000 평년기온 상승을 남한지역 14개 관측소 소재 시군의 1966년 대비 1990년의 인구증가 자연대수값에 회귀시켜 통계적으로 유의한 관계식을 얻었다. 이 관계식을 이용하여 도시화에 따른 승온효과를 제거할 경우, 순수한 지구 온난화 효과는 12월부터 4월 사이의 한후기에만 인정되며, 나머지 계절에는 나타나지 않았다. 남한지역의 한후기 일평균기온은 지구온난화에 의해 최대 0.6$^{\circ}C$ 수식 이미지까지 상승하였으며 일최저기온보다 일최고기온 상승폭이 컸다. 도시화에 따른 승온효과는 최대 0.3$^{\circ}C$ 수식 이미지에서 0.5$^{\circ}C$ 수식 이미지로 연 중(4월 제외) 고르게 나타났지만, 주로 일최저기온의 상승을 주도하였고 일최고기온 상승에는 거의 영향이 없었다.
