I don’t remember adding this to my YouTube ‘Watch Later’ playlist, but I’m glad I did. A charming documentary on a bizarre, elegant, yet absolutely enormous cloud.

Secrets of a Strange CloudYouTube
This is about the Morning Glory Cloud in the Gulf of Carpentaria, Queensland, Australia. It is an amazing atmospheric phenomenon. It is a shockwave which can be over a thousand kilometres long. Other meteorological terms for this type of formation is a shelf cloud, roll cloud or soliton. They can happen unpredictably in other places in the world but the Gulf of Carpentaria is the only location place where they happen with some degree of regularity around September and October.

Whilst we still have our heads in the clouds, ponder this strange notion — that we didn’t always know where birds went in the winter. They seemed to just vanish each year. Perhaps, rather than flying to different countries, they flew a little further.

When birds migrated to the MoonThe MIT Press Reader
Morton rejected Aristotle’s widely accepted hibernation theory, and pointed out a major flaw in the theory that the birds simply migrated to another place on Earth: No one in Europe knew where they went. They literally disappeared. He argued that returning birds, like woodcocks, appeared to drop suddenly from the sky over ships at sea.

Their round trip to the moon took one month each way, taking the distance to the moon and the length of their absence into account. There was no atmospheric resistance to impede their flight (so he had taken on board that much of Pascal’s conclusions) and the journey between the worlds was aided by lack of gravity. They slept for much of it, living off their body fat. It was all logical enough, in its own way.

You must read that article for its charming account of Domingo Gonsales flying to the Moon on his swan engine.

It’s a good job he didn’t try that trip a few hundred years earlier.

In 1110, the Moon vanished from the sky. We may finally know whyScience Alert
“On the fifth night in the month of May appeared the Moon shining bright in the evening, and afterwards by little and little its light diminished, so that, as soon as night came, it was so completely extinguished withal, that neither light, nor orb, nor anything at all of it was seen,” an observer wrote in the Peterborough Chronicle.

It was bright enough a week ago, spookily peering through the clouds, though this shot using my binoculars doesn’t do it justice.

Perhaps I need to take some pointers from the experts.

Taking good photos in bad lightPhotography Life
When the sky is gray or the sun is directly overhead, it can be tough to find inspiration for high-quality photography. My hope with this article is to share some tips that have worked for me when I photograph in bad lighting conditions – something which every photographer experiences at some point.

For all we moan about the weather, it’s endlessly fascinating. Clouds, especially. Here’s one, wandering over a lake in Austria.

Impressive ‘cloudburst’ rainstorm captured in Austrian timelapseMoss and Fog
We love this stunning capture of a cloudburst over Lake Millstatt in Carinthia, Austria. Amazingly robust rain cloud, and great viewpoint.

Here’s an interesting question to ponder after watching that.

How much does a cloud weigh?The Conversation
Summer cumulus clouds vary in size, but a typical one would be about one kilometre across and about the same tall. This means we can consider it to be a cube, with each side measuring 1km across. That means our cloud is 1,000 x 1,000 x 1,000 cubic metres in size – and this makes 1 billion cubic metres. Our cloud had only a quarter of a gram of water per cubic metre, but that’s going to work out as rather a lot now there’s a billion of them. The weight of the water in the cumulus cloud is 250,000,000 grams – 250 tonnes. This is about the same as two adult blue whales.

Looking for the next cloudburst? Perhaps start here.

Those maps (especially the vector map version) make you realise just how tumultuous and highly charged this globe of ours is — which isn’t the impression you get when looking down on Google Earth. “In prioritizing clarity and smoothness in its representation, Google Earth supports how we are consuming the planet.”

Springtime everywhereReal Life
As Covid-19 lockdowns were shuttering citizens indoors in April, for instance, Google Earth seized on the opportunity to launch a slew of themed virtual tours (e.g. the National Parks of the United States tour). It made Google Earth accessible in all browsers and added 2,500 new images to Earth View, a spinoff showcasing surreal and awe-inspiring landscapes from above. For all the feeling that Google Earth’s could be a helpful resource for learning about the climate crisis, its interface of zooming in and out and around the globe seamlessly in high-definition undermines its potential. The form comes to contradict the content: We may revel in the beauty and awesomeness of seeing the earth from the sky — and our ability to freely manipulate this view — despite the crises the imagery may depict. Deforestation on a devastating scale can take on the same aesthetic as any other “virtual holiday” on Google Earth.

A cloud gazer’s guide to every fluffy thing in the skyAtlas Obscura
Cloud-gazing, Pretor-Pinney says, is a way of “being an explorer of the sky, where you don’t have to leave your lockdown space.” The only souvenirs you’ll have will be photos and memories, but in a lonely, uncertain time, it helps to have a little perspective.

In an absolutely breathtaking clip from the PBS series Spy in the Wild, a mechanical hummingbird approaches a swarm of sleeping Monarch butterflies absorbing the warm sun of the Mexican mountains. As they wake from their sun-soaked slumber, they begin investigating their mechanical visitor.
