| 摘 要： | 本文提出了一个利用气象观测网取得的测风资料研究中距离大气扩散规律的方法。根据常规的风场观测资料和高空风观测资料,用插值公式计算地面和200m高度的水平轨迹以及水平风纵向分量和横向分量的脉动时间序列,进而用相继两条轨迹的横向距离和风脉动滑动平均法求得各类稳定度下的大气扩散参数。计算结果与同时进行的SF_6示踪实验结果和不同时进行的平衡球双经纬仪定位结果基本符合。

| Abstract: | Based on surface and upper level wind data, the horizontal trajectories and the time series of longitudinal and lateral velocity fluctuations were calculated using an interpolation formula. The lateral atmospheric diffusion parameters, for various categories of stability were estimated.
The comparison between the calculated results and field data collected by SF6 and balance balloon experiments showed no significant difference. The values obtained through SF6 experiment were larger that others due to the effect of the wind vertical shear. |
