摘要
对某地区的基本气象资料进行统计和分析,讨论并给出大气环境影响评价中典型气象日的确定方法。结合高架点源影响浓度的实例计算,可以方便地得到典型气象日条件下大气污染物的日平均浓度分布以及周围环境保护敏感目标的日平均浓度影响值,能够更为真实地反映该地区的实际气象条件对大气污染物分布浓度的影响情况。
The method to estimate typical weather day is discussed and given by statistics and analysis on the basic meteorological data. Calculating results are shown by an example to give the daily average concentration distribution to the ambient sensitive protection objects on the typical weather days. The real influence of the actual meteorological conditions upon the air pollutant distributing concentration is shown and complicated calculation is avoided hy this method.
