The analysis on temporal variation regulation and source of urban aerosol in middle China

The aerosol number concentration data in 31 various bands, which was observed by the apparatus Grimm 180 at Zhengzhou Atmospheric Constituents Station (ZACS) from the beginning of January to the middle of July in 2006, has been classified into 3 typical scales according to 3 different volume concentration peak values each one representing the various sources of aerosols to analyze their temporal variation periods by the morlet-wave method. In addition, seeing the volume concentrations of the various typical scales of aerosols as controlling factors and using the time-serials of them, the dynamics equations of the composed system of various sources of aerosols have been established to explain the volume concentration's varies with the meteorological factors in the Middle China.
