Abstract The variation of PM_2.5 concentration during 2008 to 2017 in Beijing urban area was investigated collectively using the Morlet wavelet method to understand the multi-time scale oscillations of PM_2.5. PM_2.5 in Beijing owned clear temporal variations(on diurnal, week, to seasonal timescales), especially in autumn and winter. Further analyses of wind, planetary boundary layer(PBL),and air stagnation index(ASI) revealed the mechanisms that affect multi-scale temporal oscillations of the PM_2.5. The analyses indicated: the diurnal PM_2.5 variation was closely related to boundary layer process with high concentration at nighttime and low concentration at daytime. The diurnal variations of PM_2.5 in autumn and winter was higher than that in spring and summer; the weekly PM_2.5 variation was closely related to synoptic process, and the PM_2.5 concentration was anti-correlated to wind speed and PBL height; the seasonal variation of PM_2.5 was caused dominantly by the seasonal variation of atmospheric diffusion capacity with high concentration in autumn and winter and low concentration in summer and spring.

Key words： Morlet wavelet analysis Beijing PM_2.5 periodic variation meteorological mechanisms
