Great pics! You have managed to capture the essence of pozimok as it manifests in a city.
We've had a similar cold snap. It's called takatalvi (taka- = a suffix denoting something that is situated in the back of something, talvi = winter). I once researched whether there exists an expression in the English language for that. I found several. One is "blackberry winter" they use in the southern regions of the USA when they refer to winter-like conditions occurring when blackberry bushes have started to bloom. I don't remember the others. I once visited southern England (Cambridge) at the end of March/beginning of April. It was right after a really cold spell had ended and when the weather had turned into balmy +18 C. The house I visited had a hole in the roof and it had snowed into one of the rooms in the attic. I'm guessing they have a word for this phenomenon in England, too.
Here in Lahti (60 km off the southern coast roughly in the middle) it was -9 C in the morning and it has been a little bit above freezing during the warmest hours of the day. According to the forecast, it will snow next week. Oh man, I'm tired of shoveling that white s**t...
By the way, your observations regarding the smell of different seasons is spot on. During the winter months, a faint smell of smoke and car exhaust is indeed in the air. I'd say that we should be well into the dust season by now.
I liked the picture where you had two people protected by the niches in the wall from the wind and a third one walking with her hood up. It pretty much nails what is going on.
Cheers!
