Beijing set for grey National Day as heavy smog cloaks city

Heavy smog that has already devastated northern China regions, including Beijing and its surrounding provinces, for days is expected to continue into the upcoming National Day holiday, the official meteorological service warned on Monday.

Unfavourable weather conditions are hindering the dispersal of air pollutants and prolonging the smog, said weathertv.cn, an internet outlet responsible for publishing official meteorological information, a day before the country kicks off its major holiday of the year.

Most regions of northern China are at the level four weather condition level while some regions have reached level five, the website noted. Weather conditions levels refer to a standard that describes how the overall weather condition in an area affects the dispersal of air pollutants, with level one best for dispersing air pollutants and level six the worst.
