Short summary

By using an online coupled meteorology and aerosol/chemistry model (WRF-Chem), the increase of surface PM2.5 concentration is estimated to be up to 30% during a severe fog--haze event (10--15 January 2013) over North China Plain owing to the aerosol-induced decreased surface temperature, wind speed and atmosphere boundary layer height, increased surface relative humidity, and more stable atmosphere. A mechanism of positive feedback exists and contributes to the formation of fog--haze events.
