City air 'heavily polluted' at noon while smog likely to persist

By Ke Jiayun | February 5, 2016, Friday | Online Edition

THE smog blanketing the city today is likely to persist tomorrow under sunny skies, forecasters said.

Friday Shanghai woke up to smoggy weather with its air quality index topping 100 starting 5am, reaching a slightly polluted pollution level. The cloak of smog later worsened and raised city's pollution level to a heavily polluted one at noon, with the AQI hitting 208.

The AQI peaked at 213 at 1pm with the concentration of main pollutant PM2.5 particles exceeding 160 micrograms per cubic meter, six times the World Health Organization’s safe limit of 25. By 3pm, the two readings dipped a bit to 200 and 150 micrograms per cubic meter, marking the air quality as moderately polluted.

Due to the firm weather condition and weak winds, such smog has a chance to remain tomorrow, said local weather bureau.

According to local environmental authority, a polluted condition still couldn’t be ruled out during the upcoming Spring Festival holiday. On Sunday and Monday (Feb 7-8), the Chinese New Year's Eve and New Year's Day, our city will be mainly affected by some westerly winds, which could not bring a better diffusion condition for us, and have its air quality in the "good" or "lightly polluted" tier.

Thanks to a strong southeasterly wind, the pollutants will be driven away between Tuesday and Friday next week (Feb 10-12) with the air quality being marked as "good" or "perfect". The rains on Thursday and Friday will also help cleaning the particles.

Though today's skies are mostly a mix of sun and clouds, the weather bureau warned people living in the northern areas of the city of some night short-lived drizzles or sleet.
