초록

기후이탈이 예상되는 2041-2070년 기간의 서울지방 여름(6월1일-9월30일) 날씨를 기상청 시나리오 기후자료(RCP8.5 기반) 가운데 일 최고기온과 최저기온 측면에서 전망하고, 이것이 도시농업의 주작목인 고추의 생육에 미치는 영향을 평가하였다. 이 시기의 일 최고기온 및 최저기온 평균값은 과거평년(1951-1980)의 극한기후 기준(90분위)에 근접하였다. 반면 폭염과 열대야의 경우 기후이탈시점까지 가기 전인 가까운 미래1평년(2011-2040) 기간에 이미 최빈값이 과거에 관측된 변동범위를 벗어났다. 기온의 평균값을 기준으로 본 기후이탈시점은 2040년 이후이지만, 폭염이나 열대야 같은 기후 극한지수 차원에서는 기후이탈이 이미 시작된 것으로 판단된다. 도시농업의 주작물인 고추의 생육을 대상으로 시나리오기후를 적용한 결과, 기후이탈시점과 거의 함께 노지고추 최초 정식일, 최종 수확일 등 주요 농업기후도 이탈이 시작될 것으로 전망되었다. 최초 정식일로부터 최종 수확일까지 전 기간, 즉 노지고추 재배 가능기간은 과거평년 변동 범위로부터 이탈시기가 정식일이나 수확일보다 30년 일찍 시작되었다.

Climate departure from the past variability was projected to start in 2042 for Seoul. In order to understand the implication of climate departure in Seoul for urban agriculture, we evaluated the daily temperature for the June-September period from 2041 to 2070, which were projected by the RCP8.5 climate scenario. These data were analyzed with respect to climate extremes and their effects on growth of hot pepper (Capsicum annuum), one of the major crops in urban farming. The mean daily maximum and minimum temperatures in 2041-2070 approached to the $90^{th}$ percentile in the past 30 years (1951-1980). However, the frequency of extreme events such as heat waves and tropical nights appeared to exceed the past variability. While the departure of mean temperature might begin in or after 2040, the climate departure in the sense of extreme weather events seems already in progress. When the climate scenario data were applied to the growth and development of hot pepper, the departures of both planting date and harvest date are expected to follow those of temperature. However, the maximum duration for hot pepper cultivation, which is the number of days between the first planting and the last harvest, seems to have already deviated from the past variability.
