Why is LA so polluted?
The reason for LA’s famed air pollution is geography . The LA basin is basically a semicircle of land, open to the ocean, and surrounded by mountains. The prevailing winds come from the ocean, and run into the mountain wall surrounding the metropolitan area. The city, like all cities, generates a lot of pollution. But unlike most cities, there is not much air mixing and dispersal. It stays trapped in the basin. Occasionally there is enough of a weather disturbance to ‘push’ the dirty air away and then you can see the mountains again. Then the air stagnates again and the pollutants get trapped, awaiting the next weather event that disperses it.
Why is LA a recession?

But at the same time, when all the developing countries are observing an increase in pollution day by day due to inefficient energy usage, developed countries are reducing the pollution because of availability of latest technology and ample capital. So there may exist a possibility that LA still needs some development.

Why is LA so sunny?
Another contributing factor: there's a near permanent inversion layer that sits above LA. This is due to constant high pressure systems that gives the region its famously sunny weather but also prevents smog from rising out. There's a daily onshore flow which comes in every afternoon. This blows much of the smog inland until it pushes up near the foothills and mountain areas. So contrary to the belief that LA as a whole has poor air quality, the air near the westside and coastal areas are quite good. It's just inland where it tends to be a
