ABSTRACT
This study was carried out to estimate monthly mean of daily maximum and minimum temperature across North Korea at a 30 m grid spacing for a climatological normal year (1971-2000) and the 4 decadal averages (1971-1980, 1981-1990, 1991-2000, and 2001-2010). A geospatial climate interpolation method, which has been successfully used to produce the so-called ‘High-Definition Digital Climate Maps’ (HD-DCM), was used in conjunction with the 27 North Korean and 17 South Korean synoptic data. Correction modules including local effects of cold air drainage, thermal belt, ocean, solar irradiance and urban heat island were applied to adjust the synoptic temperature data in addition to the lapse rate correction. According to the final temperature estimates for a normal year, North Korean winter is expected colder than South Korean winter by 7oC in average, while the spatial mean summer temperature is lower by 3oC than that for South Korea. Warming trend in North Korea for the recent 40 years (1971-2010) was most remarkable in spring and fall, showing a 7.4% increase in the land area with 15 or higher daily maximum temperature for April.

적요

본 연구에서는 남한 전역 기온기후도 제작에 활용된 소기후 모형을 북한의 885개 표준유역에 동일하게 적용하여 평년(1971-2000) 및 10년 단위(1971-1980,1981-1990, 1991-2000, 2001-2010) 월별 일 최저기온과 최고기온을 제작하였다. 이를 위해 북한의 27개 및 남한 17개 기상대 기온자료의 단순내삽 기후도를 관측지점 고도값으로 산출한 기온감률을 통해 고도차 보정을 하였고, 최저기온의 온난대효과와 냉기침강효과, 도시열섬효과 및 최고기온의 일사효과, 바다효과로 인한 기온 추정오차를 보정하였다. 추정된 평년 월별 평균기온의 북한 전체 공간평균값은 한겨울의 경우 남한에 비해 7oC, 여름에는 3oC 가량 낮았다. 북한의 1970년대와 2000년대 사이 기온 상승은 봄철과 가을철에 보다 두드러지는 것으로 나타났다. 평년의 4월 최고기온이 15oC 이상인 지역이 북한 전체의 36.9%인 것에 비해 2000년대에는 44.3%로 증가된 것으로 추정되었다. 또한 평년 1월의 경우 평균 최저기온이 영하 10oC 이상인 지역은 북한 전체의 13.4%이었으나, 2000년대에 들어서서 17%로 확장되었다.
