一個簡單的一維總體平均邊界層模式,用以研究無雲大氣時邊界層的演化。模式中包含凝結、蒸發、大氣輻射和地表能量收支。紊流動能(E)是由預報方程得到,紊流混合長度、尺度(?)則由Sun與Ogura和Deardorff的方法修飾得到;紊流紊數正比於?√E。地面層則使用Businger et. al.所建議的相似方程式。此外,強迫恢復方法也被利用於預報地表的溫度和濕度。 此模式被用於模擬Wangara實驗的第33天資料。模擬結果和觀測以及其他高階紊流模式的結果比較,相當的一致。
A simple one-dimensional ensemble average PBL model, including condensation, evaporation, atmospheric radiation, and the surface energy budget, is used to study the evolution of the planetary boundary layer in a cloud-free atmosphere. In this model, the turbulent kinetic energy E is predicted by a prognostic equation. The length scale (l) of Sun and Ogura, and Deardorff is modified; the eddy coefficient is proportional to √El as suggested by Deardorff; and the similary equations proposed by Businger et al. are used for the surface layer. In addition, the force restoring method is adopted to predict the surface temperature and an analogous method is used to calculate the surface soil moisture. The model is used to simulate the data of Wangara Day 33. The simulated results are in good agreement with both those observed and those produced by the other more complicated model.
