摘要
建立了一个针对小尺度深凹地形的、高分辨的、三维非静力的边界层诊断模式 ,通过求解非定常的方程组获得边界层的定常解。有选择地对影响深凹地形边界层结构的不同因子进行了数值试验研究。结果表明 ,深凹地形的深度H、坡度α以及初始地面风速u0的大小和初始风速的垂直切变 (P)等因子对边界层的结构有较大的影响 ,且模式具有较好的稳定性。
Some numerical experiments were done by using a high resolution, nonhydrostatic, three dimensional model for microscale concave terrain to study the effect factors on the structure of the boundary layer of concave terrain on micro scale in this paper. Experiment results showed that structures of the boundary layer were related closely to some factors, such as the depth H of the terrain, α angle, u 0 and P , the initial ground velocity and the vertical shear of initial velocity et al. The stablity of the model was also tested.
