Los Angeles has suffered its worst year in decades for smog and air quality, despite coronavirus lockdowns and stay-at-home orders that kept many residents off the roads.
Heat waves and wildfires, combined with other natural factors, turned the air a yellow hue that hearkened back to the bad old days of the 1990s, when the air in L.A. was practically visible.

Whoa! Wait right there. I thought all of this was because of "climate change:"
Could heat wave and wildfires be part of climate change, I wonder?
China smog, cant be from californication thier shut dwon
Subsidence inversion as a result of the sub-tropical semi-permanent high pressure system that gives southern California its beautiful Mediterranean climate.
Yep. The Spanish long ago called it, “the valley of the smoke”.
Massive levels non-compliance could be a factor. For instance, you could have a lot of people using backyard diesel generators to get around LA’s well known brownouts and blackouts. Also, I would guess that the huge population of illegals is less than 100% compliant on emissions standards.
We drove through LA on the weekend before Thanksgiving, and the traffic was pretty heavy, particularly truck traffic. By increasing truck deliveries, the lockdown may have actually made smog worse.
If California would help deport illegal aliens, they would have less pollution, less crowding, and lots more water. Their problem is their own making.
Speaking of illegals ...in Pa you are not suppose to leave the state..was wondering if anyone knows if that applies to illegals?
You nailed it...If meteorological conditions favor a strong inversion that forms daily over southern California plus wildfire smoke that will create particulate matter and becomes a process in the ozone formation then you will have bad air quality even if traffic is lower than normal. It’s all about meteorology...
As far as emissions goes, you go to a shop and get a temporary catalytic converter put on your car for $300, pass the test, then return to the shop and they take the catalytic converter off for the next customer. It’s cheaper than spending $1000 for a new catalytic converter.
Plus, the Los Angeles basin is surrounded by mountains to the North, South and East. They rise up to about an elevation of 6,000’ or so. That’s the altitude, roughly, at which the subsidence inversion forms. It caps the atmosphere above and around the LA basin and contain the effluence therein and prevents their dispersal.
During the past several years when I have visited the L.A. area, the San Gabriel mountains were visible from far away. During the 50s through the 80s that only happened the day after a heavy rainstorm.
bttt

In 1974 you could see mountains also on Sunday morning. Then from west to east they disappeared at around noon.
There is an easy explanation. Without the wind turbulent created by the millions of cars traveling all day and all night the air was not recycled back out to the Pacific Ocean where contaminants could drop into the ocean, thereby purifying the air. Instead these cars stayed in their garages poisoning the air quality inside homes by seeping fumes from their engines and gas tanks. Furthermore the lack of calming, cooling auto wind currents fostered an environment for forest burn. Then that smoke from forest burn could not be recycled back out to the Pacific Ocean. It is a vicious cycle that evolutionists are only now beginning to understand.
It’s been burning for almost 6 month straight.
Angelenos are fuming mad.
