초록

전 세계적으로 기후변화로 인한 이상기후에 대한 관심이 높아지고 있으며 이로 인한 부정적 영향에 대한 우려가 증가되고 있다. 우리나라도 기후변화로 연평균 강수량이 1910년대 1,155mm에서 2000년대 1,375mm로 약 19% 증가했으며 21세기말에는 약 17%가 증가할 것으로 전망하고 있다. 특히, 최근 10년간 1일 100mm 이상 집중호우의 발생빈도는 총 385회로, 70~80년대 222회에 비해 1.7배나 증가하는 등 기후변화로 인해 극한기상의 변화가 심해지는 것으로 보고되고 있다. 강원지방의 경우 대부분 지역이 산악으로 구성되어 있어 다른 어느 지역보다 기후변화로 인한 영향을 크게 받을 것으로 예상되며, 높은 태백산맥으로 인해 영서 및 영동으로 구분되어 산악 및 해양성기후를 모두 가지고 있는 특이한 지역이라고 할 수 있다. 이에 본 논문에서는 강원지방의 기후가 최근 어떤 특성변화가 있는지 ETCCDI (Expert Team on Climate Change Detection and Indices) 지수를 이용하여 정량화하고자 한다.

Interesting in abnormal climate is currently growing because of climate change. With this, an increasing number of people continue to show concern over the negative effects of such changes. In Korea, the annual average rainfall amount increased to about 19% from 1,155 mm in the 1910s to 1,375 mm in the 2000s. By the end of the 21st century, it has been projected that rainfall will further increase to about 17%. In particular, the 10-year frequency of localized heavy rain of more than 100-mm rainfall per day reached 385 days in the last 10 years. As such, it increased 1.7 times from 222 in the 1970s-80s. The extreme events caused by climate change is thus reported as having exacerbated over the years. Gangwon-province will suffer more from climate change than any other region in Korea because of its mostly mountainous terrain. It is a special region with both mountainous and oceanic climates divided alongside the eastern and western regions of the Taebaek Mountain Range. As such, this paper try to quantify using ETCCDI (Expert Team on Climate Change Detection and Indices) the recent climate changes in this region.
