SHANGHAI'S air quality should be a lot better today after rain and wind swept across the city yesterday but the pollution experienced on Saturday could return as dense fog still affects central and eastern China.
Rain started to fall on Saturday night while the city was enveloped in heavy smog with PM2.5 readings peaking at about 200 micrograms per cubic meter - in the "serious" range.
After yesterday afternoon's rain and strong winds, the pollutants' density dropped to 26 micrograms, a level defined as "good."
However, a cold front is expected to hit the city from the north on Thursday, bringing heavy pollution with it, said Huang Yanming, a forecaster with the Shanghai Environmental Monitoring Center.
"Pollutants brought by the northwest wind from the fog-affected regions along with pollutants to be accumulated within the city may cause pollution in the city again," she said.
The city should stay dry for the rest of the week, forecasters said.
