Clouds are fun. They can be white and fluffy or grey and wispy or dark and horrible. And they’re all just made of the same ol’ water vapor that’s in boring boggy fog (sorry Froggy).
That’s something good to keep in mind when you see something super extra crazy roaming the sky like a roll cloud.
Oh, hi. Don't mind me. I'm just a vortex to an alternate universe. Cold fusion works there. Nothing interesting really.
Yes, roll clouds act like they’re boring. They just laze around and roll over and over. They don’t really connect with other clouds. But don’t let them fool you. Roll clouds are a kind of Arcus cloud, which means there’s bound to be a thunderstorm hiding close by.
Arcus clouds form from the downdraft around a thunderstorm. This is different from their distant cousins, tornadoes, which form from updrafts. So feel free to gawk and stare and snap pics with your i-telephone. There’s no chance that funnel you see at the end of the cloud is going to dip down and throw a house at you.
Still, according to ’90s styled website, Weatherscapes.com, a roll cloud can be “both a fascinating and menacing sight while it is approaching at high velocity.”

are you a cumulus cloud whose head is getting a little sunburned? or a jewish cloud that just can’t find a kippah that fits? how about a different cumulus cloud who’s embarrassed by a lumpy head?
my mom says i'll grow into my lumps.
well look no further, because pileus clouds are just what you need. yes, pileus clouds: just place one firmly on the tip of your top for some stylish sizzle!
my pileus makes me feel more confident, more free, more ME!
so just how do you get your very own pileus cloud?
all you need is warm, moist air to push up through the top of your cumulus cloud tower throughout the day. then, wait for a layer of moist air to form up above your tower. as your moist air layer grows and floats up, it’ll cool and turn into a lovely skullcap custom made just for you!
proud to be a cloud with my rainbow pileus!
questions about pileus clouds? ask me!

it’s been awhile since i gave you everything you need to know about thunder clouds…and now it’s time to ADD TO YOUR KNOWLEDGE! or perhaps subtract. today i present to you the lowliest low-lyingliest of the fluffy stuff…
observe the gentle giant in action – the cloudiphant raises her trunk puffily as she takes just the slightest nibble at an evening sun she’s snagged against the top of a building. mmmm!! can’t you just taste those scrumptious happy rays?
i’m not the most scientific, but i am glad other people are into wearing lab coats, conducting experiments and most importantly…CLOUD CLASSIFICATION! someone’s got to keep track of the fluffy formations that float across our nation, right? if you’re like me, you look at a cloud and daydream about what its shape reminds you of, which for me is always a delicious (redundant, since they are never not delicious) plate of nachos. but it’s also cool to know what the scienc-y name of a cloud is too, just for the heckuvit!
today i present to you the cumulonimbus cloud AKA thundercloud!
i'm a very erect cloud!
according to wikipedia, a thundercloud is “a super-duper crazy tall vertical cloud that is dense (not like stupid dense), and involved in t-storms and other crap weather. cumulonimbus originates from latin: cumulus “accumuluslated” and nimbus “rain”. it is a result of atmospheric instability aka when the sky gets a little cra-zayzay.”
here’s a little more visual science:
oooh, a diagram
there are different kinds of cumulonimbus clouds – i’m already worn out from all this learning but i will continue for the sake of science.
this one’s called a cumulonimbus-incus:
incus means “anvil” in latin, ICYDK. ICYDK mean “in case you didn’t know”, in case you didn’t know. incus clouds are uber-powerful because they can cause tornados, lightning, hail, flash floods and wacked out wind. eeek! it’s like 8 greek gods in cloud form!
i hope you enjoyed this clue-in to clouds…until next time…if i can bear to learn more about clouds.
