Description
Summary:In this paper, in order to analyse the relationship of the change of PM2.5 with each meteorological factor, PM2.5 was collected in eight monitoring sites of Xi'an. The data of meteorological factors were provided by NOAA. The paper analyses the daily changing trend of PM2.5, and studies its relevancy with air visibility, air speed, temperature and relative humidity. Results show that PM2.5 density has a negative correlation with air visibility and speed, and good positive correlation with temperature. When relative humidity is lower than 60%, the relation is positive, while relative humidity is within the range of 61%∼100%, the relation is strongly negative. The paper provides a reference for fine particulate matter control and its prevention in Xi'an.
