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.
Lijiang blaze destroys old town businesses
发布者That was one day after I'd left. Anyway, Danmairen, I'm not sure if there really are fire engines that fit inside the old town of Lijiang. I even have trouble getting around without bumping my head. I'm in fact impressed the fire was contained with relative little damage.
They might have seen it coming though, there was some fire accident between Lijiang and Shangri-La during the time of my visit, which shrouded the entire Jade Dragon Snow Mountain in smoke.
Getting Away: Nanning
发布者I'm a bit late, perhaps, and biased, perhaps, because I haven't seen a proper big city since I left Kunming on my bicycle trip. But I'm positively impressed by Nanning after only one night. Green streets, air quality good, weather nice and warm in winter, big food streets at night, a selection of nice bars, and everything the western heart wants in terms of coffee, restaurants and bars.
In that aspect, it's doing better than Kunming. Con: it sprawls on forever and wouldn't make a good city to start bike rides from. You'd have to conquer forty km to get out of it first.
