Some cold air from the north will bring slight pollution to Shanghai on Wednesday with PM2.5 being the major pollutant, according to Shanghai Environmental Monitoring Center.
Sunny and cloudy days will replace wet conditions in the latter part of this week, though temperatures will drop Thursday, the beginning of the Chinese solar term of Xiaoxue, or Minor Snow, which marks the start of the cold season.
Shanghai already endured some pollution at the beginning of this week due to poor diffusion, the first since October 8 as the city’s air quality had remained good for the previous 40 days.
