Q: Has the colder weather changed/improved the air quality in your city?
After a day of snow during the week here, despite being so much colder now, the air quality is much better than the previous few weeks.
Has snow / a drop in tempreture improved the air quality where you are ?
I am in Wuhan, I think the air became worse in cold weather...
The colder it gets, the more the coal they go through and the worse the air becomes. The only time the air quality improves here is when we get a nice strong wind blowing. Then it's great!
sorrel:
yes, that what should happen. But here despite no wind, the air quality has improved
not where i am at, it has stayed the same in Qingdao, but since it has gotten colder the air has become much drier.
the air is always good and fresh in guilin so no, i dont think it changed too much
in the dongbei area it hasn't changed anything
although it's not that bad here anyway, even in summer
nope. we had a couple of days of really good air, but windy with lots of rain, now back to AQI of 150-200.... One of the 10 least polluted cities in China as it says on the posters. Pffft.
In Suzhou, AQI 100 the best days, but we got spikes at 300. Winter in China, if you loved the lack of insulation, you will love the smog 
Here in Nanning two weeks ago it was reading 214 which is the highest I have seen in two and a half years of being here. Some days back we a couple of days of heavy rain and that seemed to wash a lot of it out, down to 39. It is going back up though, today is 119.
Some days not even breathable, other days a little better, Looking forward to mid-March.
A thing the cold air brings... drop in humidity. This then increases dust generally.
Yes it has improved air quality in shanghai I think !
Nessquick:
Really ? I do not see improvement here. almost do not see the sun, how can you call it better ? 
Air quality index says that ! Air quality has nothing to do with sun ! I think it's much better than last week !
Nessquick:
yes, it is better than las week, but I still waiting for crystal clear air . like can see 50km, like back home ...
air quality is always better after the snow and rain wash all the poisons into the soil and infest my vegetables and fruit with great nutrients. damn, im getting hungry, pass me the arsonic potatoes and mercury rice.
Around 220 tonight (Dec 23) in Tai'an. it will get worse as the winter gets colder because more coal will be used to power the generators and heat the water to make the homes warm. Ad to that the increased indoor smoking and the increased use of cars etc etc. I think this is why we see more adds for FT in Northern China. The FTs are going home. Boy the Chinese are smart; they found a way to get rid of foreigners.
