中文摘要: 对1990年8月7日在北京通县地区所发生的一次中尺度天气过程中湍流场的变化进行了分析。结果表明,在中尺度天气发展过程中,近地层的湍流参数有明显的变化,从而证明了局地的输送对强对流天气的发生有促进作用。同时看出,中尺度天气过程的侵入会使局地湍谱发生明显的改变。

Abstract:The change of the turbulent fields during a mesoscale system which occured on August 7,1990 in Tongxian,the suburb of Beijing is analyzed. The results show that during the development of mesoscale system the turbulent parameters in the surface layer changed significantly. The local turbulent transportation accelerates the development of. mesoscale system in some respects, and besides the local turbulent spectra have some obvious variations during the incursion of mesoscale systems.
