【摘要】 本文讨论了广州近地层风的垂直分布特征,并在此基础上求取与大气扩散有关的一些湍流参量及风向脉动功率谱和方差,最后分析了近地层中尺度辐合随时间的演变及对大气污染的可能影响.更多还原

【Abstract】 In this paper, we discussed vertical distribution character of wind near surface over Guangzhou and evaluated some turbulent parameters concerning atmospheric diffusion and pulsed power spectrum and variance of wind direction. At last, we analysed the evolution with time of mesoscale convergence near surface and its influence on air pollution.更多还原
