According to the data from January to December 2017 provided by Pingxiang ecological environment monitoring center

which includes two conventional atmospheric pollutants such as PM2.5 and PM10 and meteorological parameters such as precipitation

wind speed

temperature and relative humidity

the influence of meteorological factors on pollution characteristics of PM2.5 and PM10 was discussed. For precipitation

especially in summer

the negative correlation between the two is the most obvious. In summer

there are most heavy precipitation weather

and the mass concentrations of PM10 and PM2.5 are at low levels throughout the year. The number of days with light pollution in winter is the most

and the average wind speed is relatively low; the number of days with light pollution in summer is relatively few

and the average wind speed is higher than in winter. There is a negative correlation between the mass concentration of PM2.5 and PM10 and the temperature

that is

as the temperature increases

the concentration gradually decreases

otherwise

the concentration will gradually increase. When the relative humidity is greater than or equal to 70%

the mass concentration of PM10 and PM2.5 is mostly kept at a low level; when the relative humidity is less than 70%

the mass concentration of PM10 and PM2.5 varies widely. The results show that the mass concentration of the main atmospheric pollutants PM2.5 and PM10 in Pingxiang city has a negative correlation with meteorological factors such as precipitation

wind speed

temperature and relative humidity. Therefore

meteorological factors such as precipitation

wind speed

temperature and relative humidity will all affect the pollution characteristics of PM2.5 and PM10 in Pingxiang city. The research results can provide certain theoretical support for air quality early warning and forecasting and air pollution prevention and control in Pingxiang city.
