Blast of north wind hits city air quality
Print Edition
Colder air from northern regions of China arrived in the city yesterday morning, bringing winds and a dip in temperatures.
Shanghai’s air quality dropped due to air pollutants brought by the southbound cold air, mainly tiny PM2.5 particles and PM10 particles, according to the Shanghai Environmental Monitoring Center.
The PM2.5 density peaked at 140 micrograms per cubic meter at 11am, almost double the nation’s standard of 75 micrograms per cubic meter.
Low temperatures in most areas ranged from around 12 to 16 degrees Celsius early yesterday morning, according to the Shanghai Meteorological Bureau.
The lowest temperatures occurred in Fengxian District, which recorded 12.4 degrees.
Today’s temperatures are forecast to be between 14 and 18 degrees.
Cool conditions are forecast to last through into the weekend.
But temperatures will increase slightly on Sunday and a high of 22 degrees is expected on Monday.
Skies will be mostly cloudy for the next few days, though it will remain dry, said forecasters.
There was a haze in part of the city yesterday morning, until winds picked up.
“Winds got stronger in the afternoon and blew the particles away,” said Man Liping, a chief service officer at the Bureau.
Today’s air quality will be better, she added.
While the cold air should keep the rain away, there is possible weak rainfall next Thursday when it warms up, according to Man.
