Grey Correlation Analysis between Meteorological Factors and Regional Air Pollution Concentration

Zhang Danmei;Fuxin Meteorological Bureau of Liaoning Province;  
Urban air quality affects the daily learning,work and life of urban residents,and is the main indicator for measuring the quality of urban environment. In order to reduce the concentration of pollutants in the atmosphere,it is necessary to study and analyze the relationship between meteorological factors and regional air pollution concentrations,and propose a gray correlation analysis method between meteorological factors and regional air pollution concentrations,which is obtained by using the indicated Kriging method. The indicator function of the atmospheric environment estimates the distribution of pollutants in the atmosphere through the indication function; calculates the air quality index and the pollutant load factor,and divides the air quality level and the air pollution level according to the calculation result; the similarity according to the shape of the sequence curve is gray The correlation analysis method determines the close relationship between meteorological factors and regional air pollution concentrations.
