摘要
近年来,邯郸市O_(3)污染严重,气象因子和前体物排放对O_(3)控制效果评估具有重要意义。利用邯郸2014年-2019年O_(3)和气象观测资料,应用Spearman相关和KZ滤波,分析评估2014年-2019年O_(3)与气象因子变化趋势。结果表明,近年来邯郸O_(3)浓度呈上升趋势,平均增长率为7.38μg/(m^(3)·a)。O_(3)浓度与温度有显著统计关系,与其他气象因子相关性大小因季节而不同。臭氧长期分量与风速的负相关性最大,短期分量与温度和日照相关性大、与风速相关性最小。KZ滤波后气象条件对O_(3)的贡献率达13%。
Ozone pollution in Handan city is severe in recent years.Meteorological factors and precursors were of great significance to the evaluation of O_(3) control effect.Spearman correlation and KZ filtering were applied to analyze and evaluate the relationship and its trend between O_(3) and meteorological factors from 2014 to 2019.The results showed that the concentration of O_(3) in Handan increased and average growth rate were.There was a significant statistical relationship between O_(3) concentration and temperature,while the degree of correlation between O_(3) concentration and other meteorological factors varies with seasons.The long-term component of ozone has the greatest negative correlation with wind speed,while the short-term component is highly correlated with temperature and sunshine,and the least correlated with wind speed.After adjustment,the contribution rate of meteorological conditions to O_(3) was 13%.
