The sensible heat flux (SHF)and latent heat flux (LHF) over Korean Peninsula ocean during recent 4 years were calculated using Coupled Ocean-Atmosphere Response Experiment (COARE) 3.5 bulk algorithm and satellite-based atmospheric-ocean variables. Among the four input variables (10-m wind speed; U, ...

플럭스는 어떻게 구해질 수 있는가? | 해양에서의 현열과 잠열에 의한 플럭스는 대기와 해수면의 에너지 및 물질이 교환되는 난류를 직접 관측해서 측정하는 에디 공분산 방법을 통해 구해질 수 있다(Businger, 1986; Kaimal and Finnigan, 1994). 그러나, 해상에서의 열 플럭스 직접 관측은 선박이나 해양 관측 기지와 같은 특정 지점에서만 이루어지기 때문에 시·공간적 한계가 있으며, 선박 관측의 경우 선체의 흔들림으로 인한 관측 오차가 포함될 수 있다(Gleckler and Weare,1997). | |
상호작용/에너지 교환 과정은 무엇에 중요한 요소인가? | 해양과 대기 사이의 상호작용/에너지 교환 과정은 해양과 대기의 순환을 유지하고, 기상/기후 시스템을 조절하는 중요한 요소이다(Kwon et al., 1992). | |
에디 공분산 방법으로 플럭스를 측정할 시 문제점은 무엇인가? | , 2003)을 이용해서 해양 열 플럭스를 산출하고 월별특성을 분석하였다. 하지만 벌크식을 이용한 열 플럭스산출에서도 해상 지역에 대한 기상 입력 변수 관측 값이 필요하기 때문에, 에디 공분산을 이용한 직접 관측과 마찬가지로 시공간적 제약이 따른다. |
