Many researches illustrated that the magnitude and frequency of hydrological event would increase in the future due to changes of hydrological cycle components according to climate change. However, few studies performed quantitative analysis and evaluation of future rainfall in North Korea, where th...

정상성이란 무엇인가? | 통계학적 의미에서 정상성이란 매개변수가 시간에 따라 변하지 않는 것으로 상수로서 표현되는 것을 의미한다. | |
기존 정상성 빈도해석이 가지는 문제점은? | 하지만 최근 전 지 구적인 기후변화로 인하여 수문자료에 비정상성이 관측되고 있으며, 기존의 정상성 빈도해석은 확률강우량을 과소 산정 한다는 문제가 제기되고 있다(Li and Tan, 2015). | |
비정상성 빈도해석의 필요한 예시는? | 실제 극한강수는 다양한 요인으로 인하여 확률분포형의 매개변수나 분포자체가 시간에 따라 변 하기 때문에 정상성을 가정한 전통적 빈도해석과는 다른 새로운 강우빈도해석 방법이 요구된다. 따라서 본 연구에서는 RCP기후변화시나리오(RCP4. |
