Beijing issued a yellow alert for smog on Tuesday.
Starting Thursday at noon, cold fronts will gradually reduce pollution in the affected region, and move it slowly southward.
Good air will return to most parts of the region from Friday to Sunday, except for mild pollution in individual areas thanks to continued cold fronts and favorable diffusion conditions.

Winter heating and vehicle emissions combined with continuous south wind and high humidity intensified the secondary transformation of gaseous pollutants such as NOx and SO2, and raised the concentration of PM2.5, according to a notice issued by the Ministry of Ecology and Environment.
