Clouds getting a bit stranger?

[Kyriakos]

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.

 

[Formaldehyde]

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:

A roll cloud is a low, horizontal, tube-shaped, and relatively rare type of arcus cloud. They differ from shelf clouds by being completely detached from other cloud features. Roll clouds usually appear to be "rolling" about a horizontal axis. They are a solitary wave called a soliton, which is a wave that has a single crest and moves without changing speed or shape. One of the most famous frequent occurrences is the Morning Glory cloud in Queensland, Australia, which can occur up to four out of ten days in October.[2]One of the main causes of the Morning Glory cloud is the mesoscale circulation associated with sea breezes that develop over the Cape York Peninsula and the Gulf of Carpentaria. However, similar features can be created by downdrafts from thunderstorms and are not exclusively associated with coastal regions.

Coastal roll clouds have been seen over California, the English Channel, Shetland Islands, Lithuania, Eastern Russia, Western Belgium, other maritime regions of Australia, off the Mexican coast in the Sea of Cortez, Uruguay, in the Canadian provinces of Alberta, over Calgary,[3]Nova Scotia[4]and Ontario, and Campos dos Goytacazes and Coronel Vivida bay in Brazil.[citation needed]

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

 

[Borachio]

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

 

[Kyriakos]

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

Looks like that cloud is spitting out birds...
