Kunming's air quality benefits from its exceptional Yunnan Plateau elevated position at 1,891 metres with the moderate spring city climate, with consistent plateau winds providing reliable ventilation across this famous City of Eternal Spring. Vehicle traffic on surrounding expressways and manufacturing and construction contribute local sources, while the elevated plateau position aids dispersal and Kunming generally maintains among China's more moderately ventilated provincial capital city environments throughout most of the year.
