Abstract :
By wavelet analysis of daily PM10 pollution index in recent 9 years in Shanghai, the multi-scale variations, primary period and influencing factors are analyzed. The result shows the air pollution pattern presents “serious in winter and slight in summer” at most scales; varies at diverse time-scales, and the primary period of the daily variations is about quasi seasonal.
