I love clouds and have names for the different kinds of clouds I see but not like "cumulus" or whatever. I have my own little cloud names, coined over a lifetime of watching the sky. Here are a few of the clouds I've seen lately that exemplify the clouds in my lexicon.
1. First up is the "Ferris Bueller" cloud--those tiny puffs that insist on making themselves seen in an otherwise cloudless and spectacularly blue sky:
This isn't the best picture, but you get the idea. When I was a kid, my little sister Mary and I would look for these clouds and the sunbeams, especially near evening; we would say that the sunbeams were God's robe coming down as he stood on the earth.
This type looks the way butter does when you melt it, with the oils and stuff separating out. It's one of my favorite cloud types. I like the different textures and the way the winds slice the clouds into different bits at different altitudes.
I have a slightly better though smaller example of a more dense cotton-batting sky here:
I remark on the "cotton-batting sky" more than any other kind of cloud cover, because it's my favorite. You'll see it before it rains or snows, when the cloud cover looks like cotton batting stretched out across the sky like a blanket, with thinner and thicker parts, but shielding out the blue behind it (except in the case of the thin batting in the first example). I wish I had a better photo, but lately every time I've seen it, I haven't had the camera.
7. I love clouds at sunset, especially the clouds high enough to look over the edge of the world:
See how there's dark gray evening clouds, shaded from the sunlight by the edge of the earth's disk, and then there are the higher clouds that are lit by the setting sun's last rays? I love these. It would be like getting an extra peek at the sunset, being up that high.
Here's another example, which also includes some really beautiful evening gray clouds, another favorite:
Clouds in the evening and at night, dimly lit by setting sun or moonlight, are beautiful to me.
8. Finally, there's the wispy clouds, smaller bits of what are usually called mare's tails:
These aren't the whole tails, mind you--just little splashes of tails.
I'll leave you with a photo of evening gray clouds I took on my way to calculus class one night. It was bitterly cold, and the moon was hanging in the sky, following the sun:
