Just a quick note... the link "Earth's Clouds" doesn't exist. Should we replace with just "Clouds"? -- 12.205.145.117 ( talk) 20:03, 3 May 2008 (UTC)
I have recently added a new article on Aviation and climate change which makes reference to cirrus clouds. I would like to add a reference to the new page to this one. I propose something like:
"If there are many cirrus clouds in the sky it may be a sign that a frontal system or upper air disturbance is approaching. Cirrus clouds can also be the remnants of a thunderstorm. A large shield of cirrus and cirrostratus typically accompanies the high altitude outflow of hurricanes/typhoons. Cirrus clouds have been observed to develop after the persistent formation of condensation trails from aircraft (see aviation and climate change)". Normalmouth 21:28, 3 September 2006 (UTC)
Cirrus intortus redirects here, but it is never talked about or even mentioned. The High Fin Sperm Whale ( talk) 01:53, 1 April 2009 (UTC)
Altocirrus? Seems still to be a popular name, probably outdated – or just for pest control or music? Some say: There is no "alto cirrus cloud". Could you please mention it and explain why this popular cloud has gone? – Fritz Jörn ( talk) 07:57, 6 March 2015 (UTC)
OK, I've now expanded the article 5x. :) Reaper Eternal ( talk) 20:30, 30 January 2011 (UTC)
There appears to be a typo in the first section, re/ the text "range from 1 ice crystal per 10,000 liters (3 ice crystals per gallon) to 10,000 ice crystals per liter (32,000 ice crystals per gallon)". I think that 1 crystal per 10,000 liters (3 crystals per gallon) is intended to be 1 crystal per liter (3 crystals per gallon). However, 1 gallon is also ~3.78 liters, so the conversion of 3.2 in the second phrase (10,000->32,000) doesn't make much sense, either. I am not implementing these fixes, as I'm not a cirrus-cloud expert, just pointing out the inconsistencies. --Anon/ 3-Feb2011
I mentioned this in a text note, but thought it could use a little more discussion. The article uses multiple temperature abbreviations, for example, "This raises the temperature of the lower atmosphere beneath the cirrus clouds by an average of 10 K (18.0 °R)."
In giving temperatures, the "R" abbreviation can mean the Rankine scale or the Réaumur scale. While they're both (little-used) temperature scales, they are distinctly different measures. I found myself scratching my head before I figured out just what was meant; I even thought it might be vandalism and looked around for the edit in which it (the vandalism) was committed. I would suggest some less-ambiguous abbreviation for Rankine (which I eventually figured out was what was meant), such as the "Ra" mentioned in Wikipedia. -- Piledhigheranddeeper ( talk) 17:10, 3 February 2011 (UTC)
Distinctly clearer! I suppose you could, if you like the {{convert}} form, use it after introducing the scales as the article now does... -- Piledhigheranddeeper ( talk) 15:17, 4 February 2011 (UTC)
Remember that the lead of the article is supposed to be a summary of the content below. For example, their formation from eyewalls in tropical cyclones is not touched upon in the lead...merely their presence near jet streams. It would be a good idea to elaborate in how they are used in short term single station weather forecasting as they precede tropical cyclones. The Cubans (and sailors) used to use this to great advantage when they forecasted (or avoided) TCs back in the late 19th century. I added a line in about it...but more could be added, if the referencing can be found. Thegreatdr ( talk) 23:53, 16 February 2011 (UTC)

I have removed the American English tag that was added to the discussion page today. The article as it currently stands (prior to it becoming today's FA) was a mix of American and British English. As per WP:RETAIN, a consistent usage should be retained in the article. It should not be decided unilaterally. Instead, a discussion should be held. If no consensus can be formed, then the first useage should be adopted.

Hello fellow Wikipedians,
I have just added archive links to 2 external links on
Cirrus cloud. Please take a moment to review
my edit. You may add {{
cbignore}}
after the link to keep me from modifying it, if I keep adding bad data, but formatting bugs should be reported instead. Alternatively, you can add {{
nobots|deny=InternetArchiveBot}}
to keep me off the page altogether, but should be used as a last resort. I made the following changes:
When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{
Sourcecheck}}
).

I hope someone might take this on. Otherwise the article should probably have a /info/en/?search=Wikipedia:Featured_article_review
Also minor points:
Should "level" be used instead of "étage"?
Does it matter that User:Headbomb/unreliable.js shows some books with warning yellow? Chidgk1 ( talk) 08:19, 8 January 2022 (UTC)
Regarding the ice crystal concentration, I have given concentrations in both SI and US customary units so that readers from both the USA and elsewhere will be able to easily understand the density. The reason I did not give the density in particles per m^3 is because the source has it in particles per liter. Reaper Eternal ( talk) 19:09, 23 February 2022 (UTC)
I am not a scientist but would https://acp.copernicus.org/articles/9/3505/2009/acp-9-3505-2009.pdf be a suitable cite? If I understand right the top of Fig. 9 is giving numbers per cubic cm Chidgk1 ( talk) 19:57, 23 February 2022 (UTC)
Unless I misunderstood they don't seem to interact with cirrus? Chidgk1 ( talk) 09:59, 13 March 2022 (UTC)
Not sure my change from "middle latitudes" was correct. As Antarctica is mentioned in body could we say in lead tropical height and height "elsewhere"? Or as height numbers mentioned in first para can we avoid further numbers in lead and just say that they are (generally?) higher in hotter parts of the world? Chidgk1 ( talk) 07:32, 15 March 2022 (UTC)
This edit fundamentally breaks the article's layout. It also duplicates images in the article and adds an infobox that is generally unwanted. (See both the consensus in both the original FAC and the FAR where this article was kept as a featured article for details.) The infobox includes both inaccurate and misleading information, and the edit summary is confusing me because all this information is already included in the article's body. SuperTyphoonNoru, can you please explain more as to why you keep reverting this information back in? Reaper Eternal ( talk) 07:16, 22 November 2023 (UTC)
