Drought Evaluation by A Drought Frequency Formula
In-Joo Kang, Yong-Nam Yoon
Abstract
Drought is a very difficult natural disaster to overcome because its beginning and end are not clear to define, and it is widely distributed in space and has long term persistence. The purpose of this study was to evaluate the drought at Mokpo using drought frequency formula suggested by Sharma(1997). The precipitation records for the period 1906-1999 at Mokpo meteorological station are used for drought analysis. The most severe drought year is found to be that of 1995, which is of the 30-year frequency, and 18 drought years are selected based on the 5-year drought frequency.
Key Words: theory of run; truncation level; drought frequency; drought characteristics; probability distribution
요지
본 연구에서는 가뭄빈도공식을 이용해서 목포지역의 가뭄을 평가하고자 하였으며, 이를 위해 Sharma(1997)가 제안한 가뭄빈도공식을 이용한 가뭄빈도해석을 실시하였다. 본 연구에서 적용된 가뭄빈도공식은 빈도계수법 형태인 연강수량 자료계열을 이용하였으며, 5년 가뭄빈도보다 큰 가뭄을 가뭄년으로 선정하고, 대상지역에 대한 과거 가뭄을 평가하였다. 이를 통해 목포지역의 가장 큰 가뭄은 1995년에 발생하였으며, 그 해의 연강수량은 613.2mm로서 30년 가뭄빈도에 해당됨을 알 수 있었다.
핵심용어: 런 이론; 절단수준; 가뭄빈도; 가뭄 특성치; 확률분포
