Characteristics of Ozone Changes and Meteorological Influencing Factors in Bengbu City

摘要

Based on the ozone monitoring data from the Bengbu Environmental Monitoring Station and the meteorological observation data from the Bengbu Ground Meteorological Observation Station from 2015 to 2019,the changing trend of ozone concentration and the effects of meteorological conditions on ozone concentration in Bengbu in recent years were analyzed.The results show that from 2015 to 2019,the monthly and daily changing curves of ozone concentration in Bengbu City had double peaks and a single peak respectively.The peak of monthly average ozone concentration appeared from April to June and in September.The peak of daily average ozone concentration occurred around 16:00,while the valley apppeared around 07:00.Among the main meteorological factors affecting ozone concentration,ozone concentration was significantly positively correlated with temperature and sunshine hours and significantly negatively correlated with relative humidity,air pressure,total cloud cover,and wind speed.
