Cold set to follow the pollution

SHANGHAI is braced for a round of moderate air pollution and colder weather from today.

The environmental monitoring center said pollutants coming from northern provinces had caused the pollution.

Tonight the air quality index is forecast to reach 165, or moderately polluted. PM2.5, the tiny airborne particles that are hazardous to health, will be the major pollutant.

Earlier today there will be slightly polluted air quality, with the AQI between 100 and 140. The index is expected to stay between 135 and 155 tomorrow.

“The majority of the pollutants will be carried into the city from northern provinces by the cold front,” a staff of Shanghai Environmental Monitoring Center said yesterday. “The possibility of short-time heavy pollution (AQI over 200) cannot be excluded in the next two days.”

According to Yangtze River Delta Meteorological Center, the northern and inland parts of the region will be most seriously affected by pollution. The situation will ease on Sunday with the arrival of rain.

According to Shanghai Meteorological Bureau, moderate haze is expected in the city today and tomorrow, with visibility dropping to 2 to 3 kilometers during the period. The haze peak will be tonight and tomorrow morning.

Meanwhile, Shanghai Meteorological Bureau issued a cold front alert last night, predicting the temperature would drop by 8 degrees Celsius within 48 hours.

The highest temperature will drop to 11 degrees today from yesterday’s 18, and the lowest to 8 degrees. Tomorrow and Saturday will range between 11 and 5 degrees.

Winter is usually the season for Shanghai to suffer more frequent air pollution due to poor dispersion conditions and pollutants coming from northern provinces.

“Shanghai will have stable weather conditions this winter, which would create poor dispersion conditions for the Yangtze River Delta region,” said Xu Jianming, an official of Shanghai Meteorological Bureau.
