      Members who are looking for the definitions of different cloud types, as well as a list of all the different classifications, should take a look at the World Meteorological Organisation’s International Cloud Atlas. This is the official reference work on cloud types. If you can’t find the answer to your cloud identification there, why not post a photograph of the cloud as a new topic in our Cloud Forum and some of our members might be able to help.

      One useful page is their complete Cloud Classification Table.

        Welcome, Edisson. It is great to hear from South America and from someone who appreciates the International Cloud Atlas.

      Had no idea the Atlas existed until I joined CAS.  It is available on Amazon.

      Shiprock45, you have me wondering what it is that is available on Amazon. I have the old ICA in hard copy i.e.

      Volume I, Revised edition 1975

      Volume II 1987 (pictures)

      The new ICA as in the top of this thread is to my knowledge on-line only and is free.

      Hello All Cloud People,

      I just finished reading Cloudspotter ‘s Guide. Loved it and am so excited to become a member of the society.

      Best.

      Hi Cloudspotters,

      I spotted this cloud a few weeks ago but I’m not sure what it is. It was not precipitating but shortly after seeing it, there was some light rain for a few minutes. Anybody know what kind of cloud this is?

      Thanks!

      Happy clouding,

      Clare

      Today’s Arizona cloud is heartbreakingly beautiful for anyone (well, me) who has ever loved a Southwest desert. That the cloud is by category nothing much just reminds me that the everyday has its own peculiar joy.  The clear definition of the limits of the rain are especially nicely shown thanks in part to the terrain, but here in Pennsylvania foothills we also for some reason take real pleasure — pride! — in seeing the edges of where a cloud finally got around to doing its thing… I love my Clouds A Day.

      Thanks for posting the link to the International Cloud Atlas. A friend from Sweden told me about a type of cloud called (in Swedish) “mother of pearl cloud” which I could not find on the CAS site. But on the International Cloud Atlas I found it’s called “nacreous” and occurs mainly in the polar regions.

      Heads Up!

      I cannot rate the International Cloud Atlas website enough, The gallery section is brilliant; you can search for photos (and subsequent explanations) by genus, species, variety, etc. The most useful website, IMO, when it comes to cloud identification.

      Also, when it comes to photometeors (atmospheric optics, from rainbows to circumzenithal arcs), this website is just *ultra*! http://www.atoptics.co.uk
