Abstract

이 연구는 한국형 체감온도지수를 개발 보급하기 위한 생명기상분야 기초연구로서 현재 기상청에서 사용하고 있는 체감온도 모델의 민감도 분석을 수행하였다. 분석 결과 한반도는 도심지역, 해안도서지역, 내륙지역, 산간지역으로 구분되었다. 평균기온의 경우, 해안도서지역에서 가장 높았으며, 산간지역에서 가장 낮게 나타났다. 그러나 최저기온은 도심지역과 해안도서지역에서 영하 <TEX>$20^{\circ}C$</TEX>이고, 내륙지역과 산간지역에서 영하 <TEX>$30^{\circ}C$</TEX>로 나타났다. 풍속의 경우, 평균 풍속과 최대 풍속이 모두 해안도서지역에서 강하게 나타났다. 그리고 동계의 지역별 기온과 풍속의 분포는 전 기간의 분포와 비슷한 경향을 보였다. JAG/TI와 Missenard 모델의 민감도 분석 결과, 기온이 체감온도에 더 큰 영향을 미친다. 그러나 영하의 온도에서는 풍속의 영향이 증가한다. This study aimed to provide a fundamental basis for the development and promotion of a Korea windchill temperature index model in the field of human biometeorology. For this, a sensitivity model currently being used by KMA (Korea Meteorological Administration) was analyzed. The results of the analysis showed that the Korean peninsula could be divided into the urban area, the coastal/island area, the inland area, and the mountain area. The average temperature was highest in the coastal/island area, while it was lowest in the mountain regions. The lowest temperature in the urban and coastal/island areas was 20 degrees below zero and that in the inland and mountain regions were 30 degrees below zero. As for wind speed, both average and maximum wind speed were highest in the coastal/island area. The distribution of temperature and wind speed in winter was similar to that of the entire period. The results of the JAG/Tl and Missenard model sensitivity showed that temperature tends to have more influence on sensitivity than any other factors. In sub-zero temperature, however, the influence of wind speed tends to increase.
