摘要
对昆明市2014-2018年空气质量和臭氧(O3)污染特征进行了分析,并结合臭氧污染观测资料和气象条件,对昆明市臭氧浓度与气象因子相关性进行了初步研究。结果表明:昆明市空气质量总体逐渐变好,臭氧浓度整体呈上升趋势,春季和夏季臭氧污染比较明显;臭氧浓度春季高,秋冬季低,高值主要集中在3-5月;臭氧污染主要出现在3-8月,7月最高;臭氧浓度与太阳辐射、气温、大气低层温度垂直分布、风速等总体呈正相关,与气压、相对湿度总体呈负相关。
This paper analyzed the characteristics of atmosphere quality and ozone(O3) pollution in Kunming from2014 to 2018 based on the ozone pollution and meteorological conditions. The correlation between ozone concentration and meteorological factors was studied. The main results were as follows: The trend of atmosphere quality gradually became better. The concentration of ozone showed an increasing tendency. Ozone pollution was obviously in spring and summer. The ozone concentration was higher in spring and lower in autumn and winter. The high value was mainly in March to May. Ozone pollution mainly occurred from March to August. The highest value was in July. The O3 had a positive relationship with solar radiation,temperature,vertical distribution of temperature in the lower atmosphere,and wind speed,and a negative relationship with pressure and relative humidity.
