| 摘 要： | 本文建立了一个均匀平坦地面上对流边界层的大涡模式，模式考虑了水汽，采用了考虑浮力和固壁影响订正的一阶闭合。并用所建模式进行了由热扰动发展的对流边界层的模拟及其对地表热状况变化响应的初步探讨性模拟工作。通过模拟认为，模式较好地反映了对流边界层的主要结构。

| Abstract: | In the paper,a large eddy model has been established to simulate the convective atmospheric boundary layer(CBL) on the flat and homogenous earth surface. In the model the vapour and its effect on M-O length have been included,and its subgrid model is one order scheme including effects of buoyance and rigid boundary. The model has been used to model convective boundary layer diagnostically,and also basically used to research the CBL response due to the surface thermal flux.Results of the model are almost consistent with documents and observation in great extent. |
