Clouds getting a bit stranger?

I hadn't come across the terms (or their corresponding phenomena) "roll cloud" and "shelf cloud".

They look quite eerie.





So what's the writing on the wall? Is this an old phenomenon?

Or is it just aliens loving puns.

 

What are we supposed to discuss here?

As you pointed out, the first is a shelf cloud and the second is a roll cloud which can even be discerned by the names on the jpegs.

 

I saw a cloud that looked like Mise yesterday.

 

There's pictures of girls on the cloud some of them have intricate patterns on their lacy undergarments.

 

Shelf clouds are far more common than roll clouds, I see one about once a year during any given thunderstorm. Its the leading edge of a severe line of storms, be it a bow echo or derecho.

I don't know much about roll clouds, and I'm not sure what circumstances they form in, or what they indicate.

 

The roll clouds do look a bit weirder, due to being detached from every other cloud formation and seemingly expanding to the horizon.



The wiki bit from Forma's link:

 

They kinda look like tubes, so those must be "the cloud" I keep hearing people talk about.

 

A plane can form a line in the sky as it continues its flight. So if one wanted to project ominous meanings to the roll cloud, i suppose it could be the massive equivalent of that line, formed by a flying object that moved so fast you never saw it begin and it passed any horizon in its covert journey virtually at the same moment

 

I saw a cloud that looked exactly like a prawn once.

 

Well, a flying Dune-Worm cloud would be even more of a bleak sight.

 

Looks like that cloud is spitting out birds...
