Residents in Beijing may see clear blue skies next week due to advantageous weather dispersing pollutants, the China Metrological Administration said on Friday.

Slight smog may occur on July 7 and 8 due to windless weather, but the blue skies and good air quality will return July 9 and remain for four days because the cold-core eddy is back, Wang Weiguo, a senior engineer at the National Climate Center said on Friday.

The cold-core eddy is advantageous weather that disperses air pollutants because it usually brings wind and rainfall, he said, adding that it usually affects the northeastern and northern regions of China.
