Four cases of an overlying inversion imposed on a stable boundary layer are investigated, extending the earlier work of Hancock and Hayden (Boundary-Layer Meteorol 168:29–57, 2018), where no inversion was imposed. The inversion is imposed to one or other of two depths within the layer: midway or deep. Four cases of changed surface condition are also investigated, and it is seen that the surface and imposed conditions behave independently. A change of imposed inversion condition leaves the bottom 1/3 of the layer almost completely unaffected; a change of the surface condition leaves the top 2/3 unaffected. Comparisons are made against two sets of local-scaling systems over the full height of the boundary layer. Both show some influence of the inversion condition. The surface heat flux and the reduction in surface shear stress, and hence the ratio of the boundary-layer height to surface Obukhov length, are determined by the temperature difference across the surface layer (not the whole layer), bringing all cases together in single correlations as functions of a surface-layer bulk Richardson number.

具有上覆反演的稳定大气边界层的风洞模拟

研究了对稳定边界层施加上覆反演的四种情况，扩展了 Hancock 和 Hayden 的早期工作（Boundary-Layer Meteorol 168:29-57, 2018），其中没有施加反演。反演施加到层内两个深度中的一个或另一个：中间或深层。还研究了四种改变表面条件的情况，可以看出表面和施加的条件独立地表现。强加的反转条件的变化使层的底部 1/3 几乎完全不受影响；表面状况的变化使顶部 2/3 不受影响。在边界层的整个高度上对两组局部缩放系统进行了比较。两者都显示出一些反转条件的影响。表面热通量和表面剪应力的减少，
