    That’s a great apseritas  time lapse. Well spotted, George. Thanks for posting it.

    in reply to: No Cloud Selector? No Problem! #211886

    Useful stuff, Davy. Who needs a Cloud Selector to jog the memory when you are armed with rhymes like those?

    Thanks for posting this, Lawrence.

    in reply to: Hi from a new member #207762

    Yes, Jamie. That is a great one. Thanks for posting it here.

    If you’d like Ian to add it to the CAS Photo Gallery, just email it to him at photos@cloudappreciationsociety.org including the location. Welcome aboard indeed!

    Best wishes,
    Gavin

    Philip,

    Rather than dragging the image, can you instead try clicking the upload window and using the dialogue box to select the image you want to upload? There should not be any problem with a Mac. It is more likely to be to do with the browser not supporting the drag and drop functionality. Let us know how you get on. Many thanks!

    in reply to: Congratulations cloudspotter team #194278

    Thanks for of this, Hans. I’ll let the mods know. I’m planning to add an About Us page listing the CloudSpotter mods. They have been hidden for too long.

    Clouds that look like thigs is a nice idea as an addition. I will discuss it with the developers.

    Thanks again!

    This is definitely a fake image.
    Here is the same cloud over… the pyramids of Egypt!

    What has happened to the state of British journalism when The Times newspaper prints a fake photo composite as if it is a real scene? Clearly, no one there has the time to check with the agency whether or not the image is real.

    When it comes to images of the sky, Photoshop has a lot to answer for.

    I think that I might have got to the bottom of this upload problem. Can you try again to see if it is working now?

    in reply to: Origin of the word cloud #193074

    Thanks for the great post, George.

    It’s so interesting that the English name for things as ephemeral as clouds derives from something as solid as a mass of rock. I wonder what the equivalent etymologies are for ‘cloud’ in other languages? What about the Dutch name ‘wolk’? They always say that the clouds are the Dutch landscape.

    in reply to: Planet Venus – global wave cloud #193068

    Clouds on other planets are fascinating. Of course they are relevant to the Society! Here, for instance, is a very peculiar cloud formation around the north pole of Saturn. We are featuring in Sunday’s Cloud a Day. It is known as ‘Saturn’s hexagon’, and it was first spotted in the early 1980s. There is no clear consensus on how it forms and why the hexagon has such straight sides. It might be something to do with oscillations produced by the shearing effects of the winds encircling the planet’s north pole.

    in reply to: New name for CAS > CAS International? #193067

    Thanks for this, Laurence.

    It is an interesting idea, but CAS has always been an international organisation. We had members in Australia, Europe and the US from very early on. I think that introducing ‘International’ into the name might be a little confusing, since it would imply that we are making some sort of change to the Society. Also, an even longer a name does begin to sound rather a mouthful.

    We have been doing some Cloud a Days about formations on other planets recently, so maybe we should be the Interplanetary Cloud Appreciation Society!

    in reply to: Rules for Order of Species, Varieties #191830

    I have never come across any rules for the order, so I don’t think there are any. Maybe they will make mention of this when the new edition of the International Cloud Atlas comes out at the end of March this year. Perhaps you should propose a system!

    in reply to: Beard-like clouds at sunset, Eastbourne, UK #191600

    If you want more explanation, Tony, you’ll see that we made a photograph of this very formation the Cloud of the Month for January.

    in reply to: Rules for Order of Species, Varieties #191599

    I’m not sure if there is a strict set of rules for this. My policy is to go in order of generality. So you would start with the genus (e.g. Cumulus, Stratus, Cirrus, etc) and then any species (e.g. lenticularis, fibratus, etc) and then any variety (e.g. undulatus, lacunosus, radiatus, etc.). Then finally, you could add any additional accessory clouds or supplementary features (e.g.mamma, virga, praecipitatio, etc.).

    This makes sense as a system, but I don’t know if it was ever actually specified. Hope that helps!

    in reply to: Member 42555 happy to be here #191598

    Hi, Barbara.

    It is great to have you in the Society. I hope the Cloud Selector will come in useful!
