I've noted here before that I'm getting pretty good at picking parking spaces that are to leeward of some major obstacle: a hill, a mountain, a large office building, etc. That helps me sleep, by not get my van smacked around by the high winds we've been having. And I'm also staying upwind from freeways and other sources of pollution, which makes me healthier.
But I've discovered another interesting thing. It's a lot quieter too. I didn't realize the degree that wind carries sound. If I'm near a freeway, and I'm either upwind or on the leeward side of a building from it, then I don't hear it hardly at all.
Days of high winds, there's more highway noise all around. Calmer days are just quieter.
Wind carries sound like it carries odors? Really? I don't understand the physics of it, but so far my experiments indicate that this is indeed what happens.
