声雷达探测在大气扩散研究中的应用(2)——混合层深度及对应的地面浓度

本文介绍如何将声雷达探测的混合层深度的变化应用于大气扩散问题.并用实例说明当某一天气过程引起混合层结构的特殊变化时,通常的模式计算不能合理地描述地面浓度特征,而利用声雷达探测的信息则能给出较合理的结果。     

APPLICATION OF SODAR SOUNDING TO ATMOSPHERIC DISPERSION-MIXING DEPTH AND CONCENTRATION AT THE GROUND

It is the intent of this paper to illustrate how to apply acoustic radar data on the variation of mixing depth in the study of atmospheric dispersion. The box model, as an example of the routine usage of acoustic sounding, has been modified. A case of the development of the structure of mixed layer, resulting from some synoptic process is discussed and the results show that the ordinaty model calculations regarding atmospheric dispersion will mislead the assessment of air quality if no remote techniques, such as the acoustic radar, are associated with,
