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.

Review: Kunming Museum
发布者Thanks for the info, I'll definitely go and pay it a visit. However with this kind of articles I've come to expect information such as opening hours. Here they are now:
Tuesday to Sunday from 9 to 17h, but they stop admitting visitors from 16:30.
Closed on Mondays (except for bank holidays).

发布者Might go, might go, but the whole accommodation insecurity bothers me. Can I pitch my own tent down? Is there parking if you come with a private vehicle?
Finally I'll let the weather decide. Summer's not known for being kind.

发布者sounds like some sort of pump is in order. Or better agricultural practices to hedge against the inevitable consequences of climate change, to help mitigate it and to protect the highlands that are so essential to our water.

发布者Futures trading was invented as a hedge for those producing the resources. E.g. as a rubber farmer, you would be guaranteed a price for your rubber if you had a future contract with a buyer. The buyer bets that not only does he obtain the product, but he also gets it for the price he was willing to pay and is in modern times of course betting that the market price will be higher than what the future contract stipulates.
