Me: *takes a grand total of fewer than 25 pictures on a 7-day cruise to Alaska*
Me: *goes to Mount Rushmore for the first and probably only time and takes approximately 30 pictures*
Me: *sees a weird cloud formation. Takes 50+ pictures of it*
But in my defense, it was a pretty weird cloud formation (these are the two good pictures, haha).
Edit: these are Kelvin-Helmholtz wave clouds, also known as billows or fluctus. They are very short-lived clouds (the ones I saw lasted less than five or so minutes) that form when two different layers of air—one moving faster than the other—meet horizontally.
I just spent like an hour browsing around this website. Clouds are awesome!
(Hey look, it’s one of them TWSB posts! It’s been awhile, huh?)
So anybody who knows me knows I like clouds and cloud classifications, right? Well, so does (as expected) the World Meteorological Association (WMO). In fact, they published the first edition of the International Cloud Atlas in 1896 and have been updating it ever since.
Well, actually, the last update—meaning the last new cloud type added—was way back in 1951 (it was the cirrus intortus, meaning “an entangled lock of hair”).
However, thanks to people who really like to look up at the sky and try to classify all the clouds in it, there might be a new addition in the 2015 edition of the Atlas. The call for the possible new cloud type, the undulatus asperatus (“turbulent undulation”), arose in 2009 from Gavin Pretor-Pinney, a cloud enthusiast and founder of the Cloud Appreciation Society (I HAVE HIS CLOUD BOOK). He was editing selections of cloud photos for the Society’s gallery when he saw several of this new type of cloud which he believed did not fit into any other variety.
To gain further support for the new cloud type, Pretor-Penney worked with Graeme Anderson, a graduate student at the University of Reading, who wrote his dissertation on the undulates asperatus. In addition, many other cloud enthusiasts have continued to document cases of this type of cloud around the world with hopes that the WMO will officially add it in 2015.
In other news: Mammatus clouds!
We be gettin’ the Chinook winds, which explains why it’s so freakishly warm today.
I found the coolest book at Bookmans this evening. It’s called The Cloudspotter’s Guide by Gavin Pretor-Pinney and it’s a half-serious, half-hilarious guide to the grey skies above us.
Using altitude as an organization factor, Mr. Pretor-Pinney discusses each cloud type, where they’re found on earth, variations of the main types, and provides awesomely-captioned photos. In what other book would you find the phrase “cloud pornography”? Or the caption, “Just as it is wrong to draw Christmas trees with the branches pointing downwards, it is also wrong to draw raindrops in the shape of tears. Children who insist on doing so should be severely punished”?
If you’re at all interested in the floating puffs of water vapor hovering above us, I’d give this book a read. It’s pretty freaking great. Totally recommend it!
