Study on the Influence of Main Meteorological Conditions on the Concentration of Atmospheric Pollutants in Jingdezhen City
The change trend of SO2,NO2 and PM10 pollutants in Jingdezhen in 2021 was analyzed,and the correlation between the concentrations of SO2,NO2 and PM10 pollutants in Jingdezhen in 2021 and the correlation between pollutants and meteorological conditions in Jingdezhen were studied and analyzed by using the typical correlation coefficient method.The results showed that:(1)The concentrations of SO2,NO2,PM10 and other atmospheric pollutants were significantly affected by meteorological conditions,showing obvious seasonal changes,and generally speaking,the average concentration was the highest in winter,the lowest in summer,and followed by spring and autumn.(2)PM10 showed obvious high in winter,lowest in summer,precipitation is the main meteorological condition affecting PM10,NO2 concentration is lowest in June-October,temperature is the main meteorological condition affecting PM10,SO2 average concentration is the lowest in autumn,and the average value is higher from April to July,mainly affected by the frequency of south-direction wind;(3)Typical correlation analysis shows that precipitation is the main meteorological condition affecting PM10 throughout the year,temperature is the main meteorological condition affecting NO2,and SO2 is affected by comprehensive meteorological conditions and has no main influencing factors;(4)If the PM10 in the atmosphere exceeds the standard,artificial precipitation is a very effective measure,if the NO2 exceeds the standard,you can take measures such as driving restrictions,traffic control,promotion of new energy vehicles,and the implementation of green travel to reduce the source strength of the mobile source,if SO2 exceeds the standard in April-July,you can require the southern heavy pollution source enterprises to take measures such as peak shifting production,shutdown and maintenance to reduce SO2 emissions.
