| 摘 要： | 本文采用二维数值模式模拟了一个坡地上夜间边界层的发展过程。所得到的结果与1974—1976年在北京北部山区得到的观测资料做了比较。模拟出的夜间辐射逆温层的厚度和形状以及下坡风的廊线都与观测事实大致相符。模式进一步改进后似可做为解决中、小尺度复杂地形上夜间边界层演变的工具。

| Abstract: | A two-dimensional numerical model has been developed to simulate the evolution of the nocturnal bou ndary-layer over a sloping terrain. The results are compared with the data observed in a mountain area north of Beijing. The depth and shape of the inversion layer and the profile of the downslope wind in this simulation agree with the observational ones. This model seems to provide a tool for solving the development of the nocturnal boundary-layer over acomplex terrain. |
