Characteristics of Air Quality in Wengyuan County and Their Relationship with Meteorological Factors
Abstract：To provide a basis for air quality potential forecasting and environmental meteorological condition monitoring, based on daily air quality monitoring data from 2016 to 2022, this study analyzed the air quality of Wengyuan County over the past seven years and explored the correlation between air quality and meteorological factors such as precipitation, sunshine duration, temperature, wind speed, and relative humidity. The results show that the overall environmental air quality in Wengyuan County has significantly improved, with a yearly decline in AQI and a significant reduction in the proportion of days with PM2.5 pollution. The proportion of pollution days with O3 as the primary pollutant has increased, indicating a shift in pollution types from particulate matter pollution to O3 pollution. O3 is positively correlated with sunshine duration and negatively correlated with relative humidity, with the highest O3 concentration occurring in autumn. PM2.5 and PM10 are negatively correlated with precipitation, with high concentration values appearing in winter. The differences in seasonal correlations are mainly due to variations in meteorological factors during different periods.
