Weak wind was the reason for the heavy smog’s return to our fair city just before the weekend, according to a Shanghai Daily report. Yeah, it’s aaalways the wind.
“Weak winds and temperature inversion — an increase in temperature with height — contributed to the light smog which was later upgraded to moderate and caused low visibility yesterday,” Kong Chunyan, a forecaster at the bureau, was quoted as saying in Saturday’s report.
The Shanghai Environmental Monitoring Center also said local emission and particles coming from the north were two main factors for the high levels of air pollutants hovering over the Shanghai.
Yesterday, the city’s Air Quality Index (AQI) remained around 150 for most part of the day, according to readings from the US Consulate. At 8:00 this morning, the AQI level rested around 160. Both are considered “unhealthy”.
Smog is determined to shroud central and east China until Wednesday, according to weather reports, “as no cold front is in sight to help disperse them”.
