CASES-99 자료를 이용한 안정한 대기상태에서의 상사 관계의 평가 = (An) Evaluation of similarity relationships using CASES-99 in the stable boundary layer

다국어 초록 (Multilingual Abstract)

Monin-Obukhov similarity theory during the stable boundary layer(SBL) is evaluated in terms of stability and large-scale environment using the CASES-99 field campaign data. Based on similarity theory, flux-profile relations, intermittency, and turbulent statistics are examined and various features of different stability regimes under the stable condition are discussed. Monin-Obukhov similarity was generally derived from Buckingham Pi theory, as a function of a stability parameter z/L and a dimensionless function ø. Basically, similarity formulas are based on a stationary atmospheric surface layer over horizontally homogeneous terrain. In this paper, for large scale forcing three types of "strong", "weak" and "normal" wind are used for the criterion of mean wind condition.
From occurrence frequency of z/L, where L is the Monin-Obukhov length, the weakly stable case of 0.01< z/L <0.1 and the strong stratification of z/L>1 are concentrated in the strong and weak wind condition. For z-less concept, the mixing length is well agreed with observation. Dimensionless wind shear ø_(m) is generally agreed with formula proposed by Businger et al. (1971) and Beljaars and Holtslag (1991) where z/L is less than 1 for the normal wind case. For the weak wind case and strong stability were z/L > 1, the relationships between parameterized formula and calculated value from observation, and similarity theory break down. Flux intermittency of turbulence might be a good index for the different stability regimes except the strong wind condition.
