Abstract
Through the analysis of meteorological factors in Nanning from 2018 to 2020, including temperature, humidity, wind speed, sunshine, air pressure and other indicators, this study summarizes the change characteristics of meteorological factors. The descriptive statistics of the air quality in Nanning in the past three years show that PM10 and O3 are the main reasons affecting the air quality in Nanning. By means of correlation analysis and stepwise regression, the correlation degree between meteorological factors and PM10 and O3 was explored, and the relationship between independent variables and dependent variables was established. The conclusions are as follows: (1) There is a significant correlation between PM10,O3 concentrations and meteorological factors. (2) Average relative humidity, average wind speed and average air temperature can explain 42% PM 10, and average relative humidity, average wind speed, average air temperature and sunshine hours can explain 66.3% O3.
