Abstract
A forest fire was one of the huge disasters and damaged human lifes and a properties. Therefore, many countries operated forest fire forecasting systems which developed from forest fire records, weather data, fuel models and etc. And many countries also estimated future state of forest fire using a long-term climate forecasting like GCMs and prepared resources for future huge disasters. In this study, we analyzed relationships between forest fire occurrence and meteorological factors (the minimum temperature ($^{\circ}C$), the relative humidity (%), the precipitation (mm), the duration of sunshine (hour) and etc.) for developing a estimating tools, which could forecast forest fire regime under future climate change condition. Results showed that forest fires in this area were mainly occurred when the maximum temperature was $10{\sim}200^{\circ}C$, when the relative humidity was 40~60%, and when the average wind speed was under 2m/s. And forest fires mainly occurred at 2~3 day after rainfall.
본 연구에서는 2005년부터 2009년까지 전라남도 지역의 기상변화와 산불특성과의 관련성을 파악하기 위해 기상요소와 산불 발생자료 (시간, 원인)를 분석한 결과, 최고온도 상승과 상대습도 감소로 인해 산불발생의 위험성이 높은 기후조건이 형성되었으며, 산불은 최고기온 $10{\sim}20^{\circ}C$에서, 상대습도 40~60% 에서, 평균풍속 2 m/s이하에서 주로 발생하였다. 이러한 기상조건은 강우 후에 2~3일이면 산불발생 위험이 높은 기상조건이 형성되었다.
