When you look at that graph, and, indeed, today's, you'll notice that the peak moments coincide with low wind speeds. Winds are very strong in spring afternoons and I believe they blow a lot of the pollution away. When the wind dies down at night, the air fills up with pollution again. From diesel trucks, certainly, but construction, too. And agricultural stalk burning.
What puzzles me is that the humidity, which reaches 100% at night, doesn't precipitate the pollution. I thought it should?
Anyway, high AQI rates are common for Kunming in spring. But that doesn't mean it isn't utterly disgusting. We should all be aware that we're slowly being killed here.
England's Prince William in China, to visit Yunnan
Posted byin certain western countries, at certain times, in certain regions and under certain conditions, hunting is a good thing. It keeps populations of e.g. fox under control. It's also the only viable excuse Americans still have for owning a gun (but not an assault rifle).
Yunnan Drifter: Nizu, the end of the road
Posted by@Kaiwen, it would seem the cycle road takes you across a bit of a scramble then drops you at what on Google Earth seems to be a dirt road along a river heading to Daocheng. I then just wonder how bad the scramble would be.

you're right. No-one should be charged just to use a road if there's no other way around.
