富顺县主城区空气污染气象条件浅析

Analysis on Meteorological Conditions of Air Pollution in Main Urban Area of Fushun County

基于富顺县主城区2016—2020年的逐日空气质量监测数据和逐日气象观测数据,采用数据统计相关分析法,筛选出富顺县空气质量主要污染物,研究了空气质量等级、优良日数、污染日数、首要污染物的逐月和四季变化规律,分析了3种主要污染物与5种气象要素的相关关系,并对2018年1月10—25日典型污染天气过程进行了初步分析。结果显示:天气条件对空气污染物的稀释和扩散有很大的影响,冷空气活动少或弱,大气静稳,则空气污染会发生和加重。

Based on the daily air quality monitoring data and daily meteorological observation data from the main urban area of Fushun County from 2016 to 2020,the main air quality pollutants in Fushun County were selected by the data statistical correlation analysis method.The monthly and seasonal variation patterns of air quality levels,excellent days,pollution days,and primary pollutants were studied,and the correlation between the three main pollutants and five meteorological elements was analyzed,The typical pollution weather process from January 10 to 25,2018 was preliminarily analyzed.The results showed that weather conditions had a significant impact on the dilution and diffusion of air pollutants.If the cold air activity was low or weak,and the atmosphere was stable,air pollution would occurandworsen.
