Dwelling where I do in Northern California, I am a beneficiary of the 1000+ fires that are going on in this region - not directly, through evacuations or actual burnings, but through smoke. Since Sunday, there has been a smoky haze around my home and all the way on my commute to my job. It's an experience I've not had before.
The only comparison I have to it is fog. The two are quite different - not just in appearance, fog being a sort of dampish grey and the smoke a sort of yellowish brown - but in the appearance the give to the landscape around them. The fog tends to conceal and then reveal, while the smoke just tends to make things disappear. Typically we can clear see 6-8 miles to the next city - now, it's difficult to clearly see a couple of miles up the road.
The other interesting thing to me is that the smoke hasn't cleared. Once it was here on Sunday, I expected it to move out by Monday. Here we are at Tuesday and, if anything, it seems to have gotten worse.
On the bright side, it makes for great sunrises and sunsets...
