Thunderstorm was a good article, but it has been removed from the list. There are suggestions below for improving the article to meet the good article criteria. Once these are addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake.

[edit] Pictures

Really nice article, April. If I might suggest a picture or two, for someone who knows how to put them in (I'm at the end of a workday, else I might do it myself). All are public domain:

http://www.crh.noaa.gov/iwx/wxpics/clouds_sun/Berryshelf.jpg (this is a shelf cloud, 78 mph winds in the storm)

Just a few among many at the noaa site. Hmm, noticed that a couple of them are shown, and others aren't.. No clue why. rgamble

its sorta boring :( zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz* The two pictures above that are still available are illustrations of lightning, which might not be the best thunderstorm pictures. -- Beland 22:53, 8 December 2005 (UTC)

[edit] Diagrams

It would be very helpful if there were some diagrams illustrating the airflow in each of the three different types of thunderstorm. -- Beland 22:53, 8 December 2005 (UTC)

Seems to have been done - feel free to re-add {{reqdiagram}} if you think it needs more. SeventyThree(Talk) 00:27, 8 June 2006 (UTC)

[edit] Expansion request: Formation

 Please help improve this article or section by expanding it.
Further information might be found on the talk page or at requests for expansion. (January 2007)

How do weather fronts and tropical cyclones give rise to thunderstorms, structurally speaking? This is hinted at but not well explained. -- Beland 03:28, 9 December 2005 (UTC)

[edit] Sources

There's quite a lot of unverified facts in here, so I've added an unreferenced tag. Annihilatenow 11:06, 6 March 2006 (UTC)

[edit] Merge from Squall

Related but distinct. Keep Squall separate. --Kbh3rdtalk 18:12, 13 June 2006 (UTC)

Agree that these two are related but Squall should remain a discrete page. Right now Squall isn't very extensive, but it has serious potential for a large article. At that point, it will be obvious it doesn't need to be totally merged into Thunderstorm. JLamb 04:00, 16 June 2006 (UTC)

If the squall is integrated into the thunderstorm article, the other types of thunderstorms have to be too. There is already an article on the supercell. So either you explain every type of thunderstorms in one article, which could be huge, OR you leave separate article like now. Pierre cb 11:00, 6 July 2006 (UTC)

[edit] GA Nomination

I am placing the GA nomination of this article on hold for 7 days for some rewriting of the introduction to better conform with WP:LEAD. I would recomend splitting off some of the information about thunderstorm activity in specific locations into a new section and possible trim some of the U.S. centric stuff. Wikipedia is a worldwide not just American encyclopedia. Otherwise it looks good. The referencing is a little light-specific facts and assertions should have in-line citations-but not enough to fail the article. Eluchil404 23:55, 4 October 2006 (UTC)

I just rewrote the lead somewhat and took out the US-centric stuff. CrazyC83 02:06, 6 October 2006 (UTC)
Thanks for the quick responce. I am now passing the article through to GA as it looks to meet all the criteria. Eluchil404 23:20, 6 October 2006 (UTC)

[edit] GA Review

The Good Article review for this article has ended, and counting the person who first passed it, it was one person for being a GA, and three opposed, therefore, I have delisted this article. Main concern was an overall lack of broadness, though especially in the thunderstorm detection section.

[edit] Paragraph requires a rewrite

" * Single cell storms form when the atmosphere is not strong enought, but there is little or no wind shear, meaning precipitation falls back down through the updraft that led to it, cooling it and eventually killing it. These storms are short lived, and last for less than an hour after becoming strong enough to produce lightning. Days with suitable weather conditions often see the repeated forming and dissipation of such storms, leading them to be known as "pulse" storms.[4]" Shorvath 05:44, 3 April 2007 (UTC)

[edit] Discrepancy

This article says: "Cloud to cloud lightning is rarely seen and is when a bolt of lightning arches from one cloud to another."

The lightning article says: "Cloud-to-cloud Intracloud lightning is the most common type of lightning..."

One is wrong, probably the former.

Watching all the flashing that goes on in a distant storm cloud makes it easy to believe that intra-cloud (within the same cloud) lightning is very common. However, it ain't what we think that's important. This page at NASA states that intra-cloud lightning is the most common. The discrepancies probably arise from the ease with which the opposing suffixes intra- and inter- are confused. --Kbh3rdtalk 21:53, 22 June 2007 (UTC)

[edit] Severe thunderstorm

It says in the article that "Severe thunderstorms can occur from any type of thunderstorm, however multicell and squall lines represent the most common forms." Also it describe how powerful a supercell is, and "In fact, most tornadoes occur from this kind of thunderstorm." So maybe supercell should be included in "severe thunderstorm"? --Natasha2006 18:10, 20 August 2007 (UTC)

[edit] nice source on particle acceleration in thunderstorms

I really have no understanding of this, but I found a reliable source on particle acceleration in thunderstorms. http://arxiv.org/PS_cache/arxiv/pdf/0708/0708.2947v1.pdf

I hope it will be of some value Teardrop onthefire 12:09, 27 August 2007 (UTC)

[edit] Ball Lightning

The article states that Ball Lightning appears in the shape of a 20-200 cm ball, is this circumference, diameter, radius, or what? It is not very well explained in the article. 71.249.149.167 (talk) 00:47, 17 March 2008 (UTC)

[edit] Merge proposal

Back-building thunderstorm should be merged into the Classification section of the article like what has been done in the past like Supercell and Single cell. Bidgee (talk) 06:14, 25 March 2008 (UTC)

[edit] Overblown

This article seems to greatly overblow the power of thunderstorms. It seems to imply that EF3+ tornadoes are common in supercells, which they are not. The article needs to be rewritten to express that most thunderstorms do not become severe, and only a miniscule fraction of thunderstorms produce tornadoes, and a fraction even smaller than that produce significant tornadoes (EF2+ per SPC definition).
