摘要
对某地区多年气象资料进行统计和分析,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情况,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 by statistics and analysis on the basis of meteorological data. (Calculating) results of an example show that the daily average concentration distribution of air pollutants to some ambient sensitive (protection) objects on typical weather days is obtained easily. The influence of the actual meteorological conditions upon the air pollutant (distributing) concentration is shown more accurately, and complicated calculation is avoided by this method.
