Some thoughts on clouds: Altocumulus Cas. & Altocumulus of a Chaotic Sky
Cloud identification began and was fulfilled within the ranges of the Temperate climate zone. Not surprisingly, "weather" is at home within this region! Having worked in the Sub-Tropical/Arid climate zone for the past 60 years, it does seem that there a additions/modifications/adaptations which need to be made to adapt to the types seen in these skies in close relation to weather events. Both Ac Cas: Ac 8 and Ac 9 are described in the various cloud atlases with reference to there being a link to air of a tropical source, but from observation within that tropical source. some enlargement would seem appropriate. Clearly, these cloud types are indicative of considerable turbulence in their cloud height above ground range. What I have seen is that Ac 9, in particular, is able to "go beserk" and create a cumulonimbus development which, once formed, adds to its mass as cloud gathers beneath the initial base, merging with it quite quickly, while cloud top expands vertically quickly topping out at typical cumulonimbus top levels. The thundery identity is now active. The base is perhaps some 10 to 12000 feet above surface. My query is about cloud identity. Is this now Cb9 in its low cloud identity? While co-existing with other Ac9 patches across the sky. The point is that the variations between Temperate and Sub-Tropical clouds are not always identified and clarified for various users

improving intro
Currently it says: "Terrestrial cloud formation is the result of air in any of the lower three principal layers of Earth's atmosphere (collectively known as the homosphere) becoming saturated due to either or both of two processes: cooling of the air and adding water vapor."

What does "adding water vapour" mean? Adding it to what and who does the adding?! Suggestion :

Clouds are formed by the saturation of air in the homosphere. This saturation occurs due to the cooling of the air or/and its contact with water vapor.

Pending edit
Why is my Oct. 31 edit not automatically accepted? I thought auto-confirmed users were supposed to be exempt from any extra anti-vandalism protections put on the article. I'm the one who did the most to get this article its GA rating. ChrisCarss Former24.108.99.31 (talk) 10:10, 31 October 2019 (UTC)
 * Huh, that's very strange. I'm not sure what's going on that's causing that. I've accepted the edit. —Tom Morris (talk) 10:43, 31 October 2019 (UTC)

in approximate ascending order of convective activity
What on earth does that mean? That's definitely not going to be understandable by a lay-reader. — Preceding unsigned comment added by 217.155.36.12 (talk) 12:12, 25 January 2020 (UTC)


 * Sorry it's taken awhile to see your comments. The sentence you're partly quoting includes an inline link too the Wikipedia article "Convection"  which I think adequately explains about that subject, but that's just my opinion.  Do you think some readers might also have trouble understanding the reference to "ascending order of" and/or "convective activity" after checking out the linked article?  If so, I guess I could just delete that sentence and let the text that follows speak for itself.  I think those who understand sufficiently will see the forms are described in ascending order of instability and convective activity, and for those to don't notice that, maybe it doesn't really matter if it's not brought to their attention.  Do you think just removing the sentence is the best solution?ChrisCarss Former24.108.99.31 (talk) 11:55, 22 April 2020 (UTC)

Suggestion for lead
Perhaps it would be a good idea to add the importance to climate change and relegate some naming details.Chidgk1 (talk) 14:54, 22 February 2020 (UTC)


 * Sorry it's taken awhile to see your comments. I like your suggestion so I'll see what I can come up with.ChrisCarss Former24.108.99.31 (talk) 12:00, 22 April 2020 (UTC)

Tabular overview citations
Re this section + table: "The tabular overview that follows is very broad in scope. It draws from several methods of cloud classification, both formal and informal, used in different levels of the Earth's homosphere by a number of cited authorities."

I believe this needs citations added to: - "several methods of cloud classification" (which methods? Without references we don't know where to look for further information, or if the methods are legitimate) and -"a number of cited authorities" (They are not cited in this passage so we don't know which of the citations in the article as a whole are relevant. And without saying who these authorities are, we don't know if they are legitimate either)

Unfortunately I think this will be down to the original author of the table to resolve, as other editors won't know the sources that were used to draw this table together. We also don't know if this table would be an acceptable to experts in the field as it seems to be the creation of the writer. 4jbptero (talk) 23:39, 15 September 2020 (UTC)
 * I'm more confused on the purpose of the table right in the lead. I understand the article is going to be broad but that info should at least be below the lead. That table has to be an issue with mobile devices. – The Grid  ( talk )  17:21, 3 March 2021 (UTC)
 * The lead and the table were combined a few years ago when both were short enough to appear together and seemed complimentary enough to fulfill a similar purpose, namely to provide a broad overview to a broad subject. However, both components have grown to the extent that they are now probably too large to be kept together, so I've separated the two and and placed the table just below the toc so the lead and the table are still close enough together to carry out their complimentary functions.ChrisCarss Former24.108.99.31 (talk) 05:20, 04 March 2021 (UTC)ChrisCarss Former24.108.99.31 (talk) 05:21, 5 March 2021 (UTC)

Record cold
Record-Low Cloud Temperatures Associated With a Tropical Deep Convective Event "In this study, we describe clustered storm overshoots in the tropical West Pacific on December 29, 2018 that resulted in the Visible Infrared Imaging Radiometer Suite (VIIRS) aboard NOAA-20 measuring a temperature of 161.96K (-111.2°C), which is, to our knowledge, the coldest on record." I checked cumulonimbus cloud and it doesn't seem like there's a place for that there, but perhaps it can go here or in another subarticle. Or maybe it's just trivia.

Adding moisture to the air
As of 2021-07-11, the section on "Adding moisture to the air" does NOT include the word evaporation.

I read, "Several main sources of water vapor can be added to the air as a way of achieving saturation without any cooling process: water or moist ground,[25][26][27] precipitation or virga,[28] and transpiration from plants[29]".

I'm changing this to read, "Several main sources of water vapor can be added to the air as a way of achieving saturation without any cooling process: Evaporation from surface water or moist ground,[25][26][27] precipitation or virga,[28] and transpiration from plants.[29]"

If this is NOT correct, I trust someone will correct me.

NICE TO HAVE: Might anyone have a table giving rough percentages of moisture from different sources? Clearly from oceans and lakes, evaporation from the exposed surface would be 100 percent of the moisture. Virga is retaining water in the atmosphere -- evaporating or sublimating before it reaches the surface. Thanks, DavidMCEddy (talk) 04:22, 12 July 2021 (UTC)

Maybe someone would like to try to get this article featured
or anyone else interested,

I noticed this article when looking through the "good" articles related to the climate change project: this looks very good and could perhaps be improved to "featured". I have to admit I gave up in frustration with my only attempt at getting an article featured so I am not going to try myself. But I see you have been doing great work keeping Cirrus cloud featured, and is an expert on this very important subject, so maybe you might consider Featured article criteria Chidgk1 (talk) 07:27, 20 February 2022 (UTC)
