Abstract Using hourly data of particles concentrations(PM10, PM2.5, PM1.0), visibility, and relevant atmospheric variables from June 1 of 2012 to May 31 of 2013 in central Liaoning Province, correlations of particles concentrations and atmospheric variables were precisely researched. The results show that the proportion of particles emission is relatively high in winter and autumn, and the proportions of particles emission in Shenyang and Anshan are higher than in the other cities in the region. The particles concentrations go through a single cycle with a high point in the morning and a low point in the afternoon. Variations of particles concentrations are in accordance with the variation of relative humility, while in opposition to the variations of visibility, temperature. Visibility relates to particle concentration closer, especially fine particles, and the correlations are more significant in summer, autumn and winter, and more prominent in Anshan and Benxi.
