| 摘 要： | 本文利用稳定层结条件下的二维夜间边界层模式,研究了自由大气中的波动及热力稳定度对夜间低空急流的发展演变的影响问题,从而初步研究了自由大气中的波动对边界层大气的反馈作用。指出了自由大气的波动对于大气边界层结构有相当大的影响,对边界层低空急流影响明显。

| Abstract: | In the paper,the effect of wave motion in the free atmosphere on the evolution of low level jet is studied by means of numerical approach.A two-dimeasion model of boundary layer is developed.The experiments of different wave length,frequencies are made to understand the characteristic features of low level jet in the boundary layer.It is found that these effects are significant. |
