Late 19th century painting.
Why are the telegraph poles pushed into the overgrowth, and why have the horse carriages been abandoned??
"These are recognized as Asperitas clouds."
Not by me. I recognize them as "Look, that shit is so trippy. We might all be dead" clouds.
"Who slipped me acid and what do I owe them" clouds
Why has no one in the comments explained what meteorological phenomena contribute to this?
Why haven't you?
Because I'm not a meteorologist and have never incidentally happened to do a deep dive on obscure or rare meteorological phenomena. As I'm sure at least someone here has done.
Good question.

Clouds have always appeared in paintings, photographs and pictures, but images captured by amateur photographers confirmed the existence of a dramatic cloud form with a roughened, wavelike base. Citizen science has now helped experts to explain how the newly-recognised ‘wave-like’ asperitas cloud is formed.
In new research, scientists combined infrared satellite images, weather forecasts and laser cloud measurements, taken at the time the rare cloud formations were reported by members of the public, to learn about the weather conditions that create them. Their findings, published in Society's journal Weather, show for the first time that asperitas is a low level cloud made of water – not ice as previously suggested – which develops its characteristic form from atmospheric disturbances, such as weather fronts and storms.
Professor Giles Harrison, who led an international research team including scientists from the University of Reading’s Meteorology department, the Met Office and the European Centre for Medium Range Weather Forecasting (ECMWF), said: “The sky is often full of clues to weather changes, and asperitas provides distinctive visualisation of complex and turbulent air motions in the lower atmosphere.”
“Reading the sky is a key part of meteorological education, warning aviators and those outdoors of potentially hazardous weather. Asperitas is now a cloud to watch out for too.”
This newly-recognised cloud was officially named asperitas by the World Meteorological Organisation in March, following a 10-year campaign for recognition.
The researchers analysing the cloud for the new study compared sightings with available meteorological data from that time and location to investigate the weather conditions that likely gave rise to the cloud formation. They found that the asperitas formation is likely to be closely associated with atmospheric gravity waves. These are generated along weather fronts and by thunderstorms, where air masses clash and cause vertical motion. This was seen in some of the satellite images analysed by the scientists.
Thank you!
Oh my! This would be great when tripping on truffles 😬
I thought they were super rare and expensive, and yet you have so many you're tripping over them?
They're a dime a dozen in EU
Oh wait you mean the mushrooms not the chocolate of the same name
Is out chocolate with mushroom essence or something?
Truffles are a type of hallucinogenic mushroom. I bought some in Amsterdam once. I think they were called philosopher stones.
Nah, fully just people going "from a distance, it kinda looks like a truffle"
A confection having a center of ganache and an outer coating of powdered cocoa or chocolate, named after the visual resemblance to a Black Truffle
As a child I only ever knew of the chocolate version of truffles and man, having had both...child me was right. Chocolate truffles are the best.
My grandma saw these one time and cherished her photos and memory of it for years
I was lucky enough to see these a couple years ago, it was very very cool to see in person!
Never seen clouds like these. Reminded me of Starry Night at first haha.
Are they only in certain regions?
They’re pretty rare, I’ve only seen them one time, and my grandma in northern Ontario only ever saw them once in her 80+ years.
It was such an event in her town that everyone went out to the street to see. When I saw them I also went into the street to take it in, but I didn’t see anyone else enjoying it
Apparently they’re more common in the US plain states (not sure what they include)
Saw them often when I lived in Oklahoma
Isn't this the global warming cloud? As in this type of cloud is becoming much more common due to global warming.
Wouldn’t surprise me... Ontario weather is becoming increasingly like the us midwest with tornadoes.
If you paint that on a canvas minus the human Infrastructure I’d Frame it.
Just you wait…
You haven't seen me paint
You haven't seen me frame
You haven't seen infrastructure (if you live in __________)
Makes me want to scream for some reason.
This looks like it was painted by Bob Ross
Pictures don’t do this justice, you need to see these irl they are amazing!
I'm going to need a really long spoon.
