Winter is coming ================ The temperature dropped to +4ºC this night. It’s not winter yet, but certainly the beginning of late autumn. Yesterday I’ve started reading _The Cloudspotter’s Guide_ by Gavin Pretor-Pinney. Not the best timing, as soon I’ll be seeing nothing but grey overcast (and now I know that type of cloud is called _Stratus nebulosus opacus_) for weeks is not months. But well, I still have a few weeks until that, so I’ll have a chance to observe those _Cumulus_ forming. And I enjoy the book so far.
