自由大气的扰动对边界层结构影响的二维数值研究

A TWO-DIMENSIONAL NUMERICAL STUDY OF THE EFFECT OF THE DISTURBANCES IN FREE ATMOSPHERE ON THE STRUCTURE OF PBL

在中性正压的行星边界层中,考虑边界层顶的负随时空变化的一般情况,在的假定下,用数值方法解边界层运动方程得到风及边界层某些参数的分布。还计算了边界层顶垂直速度,发现和Charney等人的结果不同。

In this paper, under the assumption of K=l2 the motion epuations ofthe PBL are numerically solved for the general condition that the wind at the top of the PBL varies with time and spatial coordinates, and the distribution of the wind and some parameters are thus obtained.Furthermore,the vertical velocity at the top of the PBL is calculated, the result is different from Charney's classical one.
