Cold air from north to help clear capital's skies

Pollution set to linger in center and south of Beijing-Tianjin-Hebei area

Meteorological conditions that don't favor the dispersal of pollutants are to blame for air pollution in the Beijing-Tianjin-Hebei region, with winds carrying pollutants from other regions, making the situation even worse, authorities said.

While cold air from the north will help clear the pollution on Tuesday, moderate to heavy pollution may linger in cities in central and southern parts of the region for the day, a national joint research center on the causes and control of air pollution said on Monday.
