| 摘 要： | 本文详述了一个具有横风切变效应的风洞实验新技术,实验结果表明,如果风向在地面上随高度以0.02(°)/m变化,当进行扩散模拟实验时,若原型长度尺度大于6km时,忽略罗斯贝数将会导致严重的误差。

| Abstract: | In this paper,a new experimental technique with crosswind shear effect is described in detail.If the rate of wind directional variation from the earth surface is about 0.02(°)/m,results of this experiment demonstrate that the neglect of the Rossby number can lead to serious errors as the modoling of diffusion in a prototype with length scale greater than six ometers. |
