COOLER weather returns today with a high of 13 degrees Celsius, a marked change from yesterday's sunny, warm high of nearly 20 degrees, forecasters said.
Arrival of a cold front will usher in a breezy, cloudy day today and a low of 8 degrees. Mild and windy conditions with skies that will be overcast to partly cloudy will continue into early next week, with lows staying at 8-10 degrees Celsius and highs rising to as high as 16 degrees.
After days with excellent and good air quality, it was lightly polluted yesterday due to an accumulation of local pollutants with little wind.
The average density of top pollutant PM2.5 within the most recent 24 hours rose from a low of 40 micrograms per cubic meter at 5pm Wednesday to an average of 76.7 at 5pm yesterday, surpassing the nation's limit of 75 micrograms per cubic meter.
"With the arrival of a cold front ... the air quality is expected to get better under the effects of a northeaster," said Man Liping, an officer of the Shanghai Meteorological Bureau.
