Another one of those days where I kinda wish I had taken at least some meteorology at some point (only “kind of” because I wouldn’t want to miss any of the stuff I actually took…). But on my way to work I saw the clouds below:

The internet says they might be cirrocumulus undulatus clouds.

In any case, the wavy clouds started to disintegrate into cirrocumulus-like clouds.

But whatever they were, they were very pretty!
Meteorologists out there (Torge! :-)) – what kind of clouds were they and why did they form?
