Needed Corrections

"Cumulonimbus – rare cloud similar to mammatus, attached to underside of CB" not sure what it should say but it's not cumulonimbus...Dr Denim 19:46, 1 June 2006 (UTC)[reply]

Nimbostratus clouds are low clouds with raggedy bottoms and bring continuous rain events. Cumulus clouds develop vertically and can cross stated altitude descriptions. Cumulonimbus clouds are not rare, these are "thunder clouds" and one of the 10 major cloud types. Alaskan teacher (talk) 05:02, 22 October 2008 (UTC)[reply]

Hole Punch

Are 'Hole Punch' clouds cassified? I'm linking some articles/examples for anyone interested in answering or adding to the article.

It's also noteworthy that a few of the sites I'm linking are actually conspiracy sites -- people insisting that UFOs, jet planes, etc. cause this kind of formation. Unfortunately, they don't appear to be sourced.

What say? --Spesek (talk) 17:50, 9 December 2007 (UTC)[reply]

Then there's Asperatus - a new type of cloud - looking like elongated mammatus. Apparently they are low to medium-level clouds. No proper description yet.

I agree Hole - punch clouds or Fallstreak hole with visible trails of ice crystals dangling below once some droplets freeze they rob others of moisture and start to descend

Cloud Types

I have made extensive changes to this article to address concerns addressed above, including removal of non-existant altostratus 'species'. Cumulus and nimbostratus are now grouped into a 'low to medium-level' height range category that recognizes the wide range of altitudes at which these genera may be found (Nimbostratus has been variously classified as middle, low, and even vertical by different authorities). Will make further improvments as time permits. User:ChrisCarss Former24.108.99.31 (talk) 23:13, 28 July 2010 (UTC) Special:Contributions/ChrisCarss Former24.108.99.31 (talk) 23:16, 28 July 2010 (UTC)[reply]

More improvements with thumbnail descriptions now provided for all cloud types and sub-types in these lists. More details provided about clouds that form above the troposphere and around other planets in our solar system. Low-to-medium level height range category retitled 'low to middle with some vertical extent'. I hope this last edit won't be seen as 'original research' but as the ultimate in Wikipedia impartiality. As noted above, nimbostratus has been classified as as low, middle, and vertical by different authorities, so this latest title takes all 3 designations into account. Cumulus has been classified as low and vertical, and is also known to form in the middle height range under conditions of very low humidity. Cumulonimbus bases form in the same broad range of altitudes as cumulus and has greater vertical extent, so its height range designation has been clarified as 'low to middle with considerable vertical extent'. [[User:Chris

Low to middle clouds with some or considerable vertical extent have been retitled respectively as "moderate vertical" and "towering vertical" for the sake of brevity and to conform with Wikipedia main article 'Cloud'. The 'low to middle' designations have been moved from the main titles to captions or descriptions next to the titles. Another significant change is that since this is a list and not an article, it seems logical and appropriate to list the major cloud types in descending order of altitude from extremely high (Noctilucent) to low (Sratocumulus and Stratus). The moderate and towering vertical clouds are generally not classified by base height range, and so are listed after the low clouds in ascending order of the average height of the cloud tops of both the main genus types and their species. This overall new arrangement has the introductory text, which ends with the stratospheric and mesospheric clouds, leading straight into the list which starts with those same cloud types. This new arrangement from highest to lowest then to the vertical types conforms with the same sequences used for the templates at the bottom of the page. The idea of having the first list in order of altitude compliments a subsequent list with the cloud types arranged in alphabetical order.

Formation of Clouds

"Clouds form in the Earth's atmosphere when water evaporates from oceans, lakes, ponds, and even streams and rivers; and by evaporation or transpiration over moist areas of Earth's land surface.^[1] The vapor rises up into colder areas of the atmosphere due to convective, orographic, or frontal lifting. This subjects the rising air to a process called adiabatic cooling."^[2]

"The water vapor attaches itself to condensation nuclei which can be anything from dust to microscopic particles of salt and debris. Once the vapor has been cooled to saturation, the cloud becomes visible. All weather-producing clouds form in the troposphere, the lowest major layer of the atmosphere. However very small amounts of water vapor can be found higher up in the stratosphere and mesosphere and may condense into very thin clouds if the air temperatures are sufficiently cold. The nephology branch of meteorology is focused on the study of cloud physics".

- I've moved the section above out of the main list article pending if there is a clear editorial consensus as to whether it belongs in the 'List of cloud types'. The topic of cloud formation is well covered in at least 2 other articles; 'Cloud' and 'Cloud physics'. If this section moved from the main list contains any details about cloud formation not covered in the other articles, then I think these details should be moved to the other articles.

- This article is a list only, and deals only with cloud classification. As such, it need not be weighed down with non-classification theory already covered elsewhere. So for the sake of eliminating redundance, I've moved it at least temporarily to this talk section so the issue of what sections belong in which articles can be discussed with an eye towards elimination redundance.

Cloud Codes Query

This page uses a V-x system to enumerate the possible varieties of cloud, from 1-93 (e.g. V-42). The references don't allude to this, as far as I can find? Where does this system come from - and if it's created here on Wikipedia, where did the associations of possible varieties (and combination of varieties) to species come from? 194.207.139.186 (talk) 18:41, 10 August 2023 (UTC)[reply]
