Abstract

Evaporation is an essential parameter in Global water-energy cycle and the variability of evaporation affects water resources planning and managements. In this study, the temporal variability of pan evaporation data was analyzed and trend analysis of the data using Mann-Kendall test. The relationships among evaporation and rainfall, air temperature, humidity, cloudness were analyzed. Even though the longterm trends of air temperature and rainfall increases, that of evaporation except Jinju and Yeosoo results decreases as worldwide observations. Results demonstrate that decrease of pan evaporation represents increase of terrestrial evaporation as Brutsaert and Parlange(1998)'s analysis.

증발은 자연생태계의 에너지 및 물수지에서 중요한 역할을 담당하고 있고, 증발량의 변화에 관한 연구는 수자원의 계획 및 운영에 있어 중요한 요소이다. 본 연구에서는 1973-2004년, 32년간의 4월-10월 사이 7개월 동안의 증발량 평균값과 각 월별 증발량의 변화경향을 파악하고 추세 분석을 위해서 Mann-Kendall 검정을 실시하였다. 또한 증발과 관련된 기상요소들 즉 기온, 강수량, 습도, 전운량, 풍정합 등과의 상관관계도 분석하였다. 전 세계 여러 지역에서 관측된 바와 동일하게 기온 및 강수량이 증가함에도 불구하고 여수와 진주를 제외하고는 모든 관측지점에서 증발량은 감소경향을 나타내었다. 연구 결과는 팬 증발량의 감소가 실제 증발량의 증가를 나타낸다는 Brutsaert와 Parlange(1998)의 해석처럼 우리나라의 팬 증발량의 감소 경향은 실제 증발량의 증가를 나타낸다고 판단된다.
