| 摘 要： | 本文利用一维二阶矩闭合边界层土壤藕合模式模拟了夜间边界层中辐射雾的形成、发展和消亡过程。结果表明:湍流场和辐射场的相互作用对辐射雾的形成和发展有重要的影响。雾中液态水含量以及一些特征参量呈现准周期振荡变化，这种振荡和雾中湍涡的涨落有关。模拟结果和观测基本符合。

| Abstract: | A one-dimensional second-order closure PBL model coupled with soil model is applied to simulate the formation, development and dissipation of radiation fog. The results show that the interaction betWeen turbulent field and radiative field plays a very important role in the formation and development of radation fog. The simulation also shows a series of pronounced oscillation in some fog parameters such as the liquid water content. These oscillations may be related to the flactuation of turbulent eddy in fogs. The results are in qualitative agreement with the observation. |
