A fact from Cirrus cloud appeared on Wikipedia's Main Page in the Did you know column on 3 February 2011 (check views). The text of the entry was as follows:

Did you know... that cirrus clouds (pictured with a fire rainbow) cover an average of 20% to 25% of the Earth's surface at any time and can produce glories, fire rainbows, and sundogs?

A record of the entry may be seen at Wikipedia:Recent additions/2011/February.

Wikipedia

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)[reply]

Aviation and climate change

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)[reply]

Cirrus intortus

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)[reply]

This has been fixed. Reaper Eternal (talk) 01:23, 6 February 2011 (UTC)[reply]

Inflation

OK, I've now expanded the article 5x. :) Reaper Eternal (talk) 20:30, 30 January 2011 (UTC)[reply]

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

Temperature notation

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)[reply]

I removed the {{convert}} template and replaced it with 10 Kelvin (18 Rankine). Reaper Eternal (talk) 17:28, 3 February 2011 (UTC)[reply]

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)[reply]
