울산지역의 해륙풍장을 해석하기 위해 3차원 중규모 지역기상 수치모형을 개발하여 흐름장의 변동을 수치해석하였다. 식생의 영향을 고려한 지표면 열수지모형을 이용하여 지표면의 온도 및 습도를 결정하도록 하였다. 그리고 접지층에서의 연직방향 확산계수는 Businger의 모형을, Eckman층에서는 Yamada의 난류 closure모형을 사용하여 계산하였다. 그 결과 울산지역의 해륙풍장의 거동특성을 해석하는데 있어서 본 모형은 효과적임을 알 수 있었다.

Abstract

A three-dimensional numerical model for the simulation of meso-scale local circulation is developed and it is applied to the land and sea breezes which take place around Ulsan. The surface temperature and moisture on the land are determined by means of the surface heat budget with a layer of vegetation considered. The vertical diffusion coefficients of momentum, heat and specific humidity at the surface layer are obtained by the lever-2 model of the turbulence closure proposed by Yamada (1982). This model proved to be effective in simulating the structure of the land and sea breezes around Ulsan.
