[edit] Colour of Occluded Front Symbols

Often on TWC's weather maps, the occluded front is purple. Andros 1337 16:33, 14 May 2005 (UTC)

Hrm, yeah I've seen it both ways. The important thing is really the shape, as I don't think the colour is standardized. Do you think I should change it, or what? -Lommer | talk 00:51, 15 May 2005 (UTC)
Yes, change it to avoid confusion with the stationary front. Andros 1337 01:15, 17 May 2005 (UTC)
Ok, it's taken me little while, but I've finally updated it. -Lommer | talk 00:25, 21 May 2005 (UTC)
Just so you lot know, in the UK occluded fronts are hardly ever purple, mostly just alternating red/blue. Not worth changing the picture though. --Albert 19:46, 16 July 2006 (UTC)

[edit] Commons

Ther are some images at commons, see here. Examples: Image:Warmfrontokklusion en.png, Image:Kaltfrontokklusion en.png and if you want to translate them also here and here. --Saperaud 3 July 2005 08:07 (UTC)

Those show warm & cold occlusions which I am currently revising for Geography A-level. These require a bit of explanation and perhaps give good reason for a separate 'Occlusion' article.--Albert 18:20, 30 May 2006 (UTC)
There is currently a disconnect between the United States NWS surface analyses and other countries on the depiction of occlusions at this time. The U.S. version always starts with a cold pip regardless, and doesn't switch the direction of pips behind the cyclone like the U.K. does. I doubt this was an intentional move, but it has been that way for years now. Thegreatdr 02:53, 4 June 2006 (UTC)

[edit] Splitting Up

I think it would be a good idea to have a seperate page for the different fronts. Give a basic description of them (the current ones). Then have a link to their main page which would have more in depth detail. What do you all think? -- Jesusfreak 03:13, 5 May 2006 (UTC)

I agree. To avoid confusion, it would be best to separate the topics, even if they share something in common.--Wired2Narnia Christchild

It is probably not required. The weather section is riddled with stub articles, and this article is one of the stubs. If this page gets really long, it would make more sense to separate this page out into multiple articles. Thegreatdr 17:20, 25 May 2006 (UTC)

[edit] Page Name Change

Changed the name of the page from Weather Fronts to Surface Analysis - Weather. The page Weather Maps was so closely related I added the information from the page to the top of this one and left a link to this one. Improved the format of the resultant page and included information on mesoscale boundaries which are seen and analyzed on the surface analyses over the United States. Included the links to the NWS Unified Surface Analysis and its associated manual. References also were added. Expanded the history section initially in the weather map page to more fully document the early rise of surface analyses. Thegreatdr 02:26, 26 May 2006 (UTC)

Good idea. But is 'Surface Analysis - Weather' too complicated/odd a title? What about just 'Surface Analysis'?--Albert 16:21, 30 May 2006 (UTC)
I'm worried other disciplines may have techniques known as surface analysis. I'll change it to Surface weather analysis, to sound less awkward. Thegreatdr 17:14, 30 May 2006 (UTC)

[edit] Dry line definition

By definition, drylines form in response to downsloped air of the higher terrain of the Rockies

I find it very difficult to believe that this is the definition of a dry line. Surely this phenomenon occurs elsewhere in the world? -dmmaus 05:36, 28 June 2006 (UTC)

I've marked it up with "citation needed." -- Captaindan 20:14, 12 July 2006 (UTC)
The original definition was modified for the broader audience. The Bluestein definition is clear about dry lines lying east of the Rockies, however. To my knowledge, no European, Asian, South American, or Mexican weather maps depict the dryline. Thegreatdr 18:56, 15 July 2006 (UTC)

[edit] Reformating

Now that the article has been nominated for GA status, the references have been reformatted to the style used on other weather-related Wikipedia pages. A See Also section has also been introduced. Thegreatdr 19:33, 22 October 2006 (UTC)

[edit] Good Article

I've read the article and found it to be quite well written, and for its length, quite comprehensive. As such I have decided to give it GA status. However, are these the only symbols used in SWA? Maybe more content for aviation symbols and info? Sjschen 21:49, 5 November 2006 (UTC)

I have added a graphic showing common aviation symbols for ongoing weather shown on weather maps. There are other symbols that are sometimes plotted, such as for turbulence, which are not included on the graphic. Thegreatdr 17:08, 2 December 2006 (UTC)
The article is good...is it time for peer review? --Hard Raspy Sci 18:21, 31 December 2006 (UTC)
It has been submitted as a FAC, which has already led to some improvements. Feel free to make suggestions. Thegreatdr 15:55, 20 April 2007 (UTC)

[edit] Q about Outflow boundaries/squall lines

in the article under the Outflow boundaries/squall lines section, it mentions "with the resultant Mesoscale Convective System (MCS) forming at the point of the upper level split in the wind pattern running southeast into the warm sector parallel to low-level thickness lines." The word "southeast" piqued my interest... is this statement only true for the Northern Hemisphere? And if so, should it be changed? 68.146.221.56 13:04, 8 January 2007 (UTC)

Probably so. Good catch. Thegreatdr 00:53, 17 January 2007 (UTC)

[edit] Peer review and FAC

Extensive comments have been left for potential improvements to this article. These comments can be found at the peer review (see box above for more info). Later. --Jayron32|talk|contribs 05:34, 10 May 2007 (UTC)

Your comments were very helpful...thank you. Thegreatdr 15:30, 10 May 2007 (UTC)
There have been no comments left with this article, either in peer review or FAC, for about 2 weeks. If interested, review the article for FAC and provide comments on whether or not additional changes are needed before FAC can be supported. Thegreatdr 13:13, 26 May 2007 (UTC)

Kudos to those that worked to get sfc analysis to FA status, are there any plans for a similar article on upper air analysis? Evolauxia 22:56, 29 May 2007 (UTC)

Upper air analysis would easily fit within the weather map article. Thegreatdr 09:29, 30 May 2007 (UTC)
The weather maps article is the surface analysis article, which is fairly complete yet not too cumbersome, so the addition of upper air analysis seems reasonable. Once that was done, a name like map and chart analysis would be appropriate. Evolauxia 06:30, 31 May 2007 (UTC)
My bad...I meant weather map, not weather maps. That article is different from this one. Thegreatdr 19:52, 10 June 2007 (UTC)

[edit] Links

Occluded Front (with a capital F) redirects to this page, and not Occluded front (lower case f). Is this a mistake? --El Pollo Diablo (Talk) 13:07, 25 July 2007 (UTC)

[edit] Picture

Do we have to have a map of the United States as the definitive example? Couldn't we enhance the world view of this article by perhaps using a surface weather analysis of somewhere more obscure? Black-Velvet 06:00, 24 November 2007 (UTC)

If you have a case of a non-copyrighted surface weather analysis from another country, be bold and include it. As far as I know, the U. S. is one of the only countries where work of its federal government is free of copyright restrictions, and therefore able to be included within wikipedia. Thegreatdr (talk) 22:18, 21 January 2008 (UTC)

I know everything about weather. —Preceding unsigned comment added by Broworker122 (talk • contribs) 06:58, 24 November 2007 (UTC)
