The information from this page needs to be merged with another recently created Numerical Weather Prediction page
Mayhap the technique of inserting 'bogus' data' to fill in the gaps left by observations should be briefly mentioned...although I'm not really sure if it's relevant enough to be inserted...anywho... Dr Denim 12:38, 31 May 2006 (UTC)
Please revert back to the 10 Jan 06 version. The North American Mesoscale (NAM) run at the National Centers for Environmental Prediction (NCEP) is not a model, it's a placeholder. Currently the model designated as the NAM is the Eta model. Some time in the second quarter of CY06 NCEP will begin running the NMM-WRF as the NAM.
Incidentally, the Global Forecast System (GFS) is also a placeholder. Currently the AVN model is designated as the GFS, but if NCEP ever replaces the AVN model with a global version of WRF, or any other model, it will still be designated as the GFS.
...it needs inline citations. Thegreatdr ( talk) 19:18, 13 January 2008 (UTC)
Both this article and the "Atmospheric model" article contain a section "Global models" which is a list of models. Theses are similar but look to have diverged a little. Not nice. So I suggest that this list be maintained in just one article (not both), and that the other article contains a cross-reference (e.g. wikilink) to that first article. If that is the right way to go, my guess is that this (NWP) article might be the better home, as some models are (presumably) more than just atmospheric. Feline Hymnic ( talk) 23:30, 1 January 2009 (UTC)
We're down to two sections which remain reference-less, and a few other passages which need refs. Some external links likely need to be weeded out. Other than a little more content, significant progress has been made improving this article during this past week, and I can see GAN on the horizon. Thegreatdr ( talk) 18:49, 1 January 2011 (UTC)
For the citation looked for in the lead, we already have a reference for it below (Cox). Did you want another ref placed up there as well? Thegreatdr ( talk) 20:58, 2 January 2011 (UTC)
Suggestion: the picture File:NAM 500 MB.PNG at the top is almost indecipherable; massive information overload for the beginner! Even worse, it took me ages to see even which part of the world it is (I suspect, as a foreigner, I might see North America in very pale outline somewhere under there), let alone interpret any data on it. How about something from ECMWF such as [1], copyright permitting? Feline Hymnic ( talk) 18:29, 3 January 2011 (UTC)
I'm setting up this section as a drop-box for comments about the article, so that those with more knowledge can pick them up, assess them and act (or not) upon them.
Do not like the recent revision, in separating out the sea ice and SSTs into their own tiny sections. First off, those section aren't likely to grow from their current tiny size, which would prevent GANing and FACing. Secondly, they are initialized in global atmospheric models, climate models, and likely ocean modeling, so why not keep them somewhere above the subsections since they apply to all of models mentioned (except maybe air quality)? I've gone ahead and reverted the edit. Thegreatdr ( talk) 20:59, 8 January 2011 (UTC)
So what is left to do before a GAN/FAC run? Titoxd( ?!? - cool stuff) 04:46, 12 January 2011 (UTC)
I've reviewed the article for GAN. In addition to my comments, be sure you address the above comments by Feline. --♫ Hurricanehink ( talk) 04:21, 17 January 2011 (UTC)

All in all, a good read. There are just some minor writing things that I'd like to see worked on. As such, I put the GAN on hold. Let me know if you have any questions. --♫ Hurricanehink ( talk) 04:18, 17 January 2011 (UTC)
Do we go for the bronze star? Titoxd( ?!? - cool stuff) 02:15, 18 January 2011 (UTC)
Just a quick note of congratulations to Thegreatdr and Titoxd for achieving this. Good stuff! Feline Hymnic ( talk) 23:36, 23 January 2011 (UTC)
The following sentence in the lead raises some questions in my mind:
First, the use of the word 'govern' here seems odd. I would think that the equations model the behavior of the atmosphere, rather than govern it. Second, are the equations themselves chaotic, or is it the fact that any small imprecision in the input causes a chaotic variation in the output? Thank you.— RJH ( talk) 20:16, 21 February 2011 (UTC)
Congratulations! Good work! Nageh ( talk) 17:21, 3 April 2011 (UTC)
How is a cool, interactive, timeline of the exact article linkspam? I was going to donate this technology to Wikipedia. Granted, this article doesn't have a lot of dates in it. I am not running any ads on this page, it just displays the article in a unique way. Jroehl ( talk) 01:58, 10 August 2011 (UTC)
Titoxd,
The link I posted was:
http://wikitimelines.net/?tl=ECL6A1A2X&todo=showtl
And I even tested it, and it came up correctly. The timeline about U.S. history is the default timeline if no parameters are passed in the URL. I dont know how you got the wrong timeline. And thanks for your informative and speedy reply Titoxd. Jroehl ( talk) 02:10, 10 August 2011 (UTC)
Does wikipedia strip off parameters passed in a URL when it is an external link such as the following:
http://wikitimelines.net?tl=ECL6A1A2X&todo=showtl
Something seems to be inserting a "/" before the question mark when the page is rendered such as:
http://wikitimelines.net/?tl=ECL6A1A2X&todo=showtl
Which nullifies the parameters and brings up the default timeline, which is the history of the United states. I cant figure that out. Jroehl ( talk) 15:10, 10 August 2011 (UTC)
Never mind, the URL is:
http://wikitimelines.net/tl3.fwx?tl=ECL6A1A2X&todo=showtl
I shouldnt be working this early in the morning. I am making stupid mistakes. Jroehl ( talk) 15:23, 10 August 2011 (UTC)
It is impossible to solve these equations exactly, and small errors grow with time (doubling about every five days).
And yet we can predict to a tenth of a degree the temperature in 80 or 90 years. Imagine that. — Preceding

"height or pressure" you mean "height AND pressure" right? — Preceding unsigned comment added by Odarcan ( talk • contribs) 21:56, 10 August 2011 (UTC)
Milutin Milanković should be mentioned in this article because he initiated numerical modeling of the climate.-- Свифт ( talk) 09:21, 4 April 2012 (UTC)
I understand that data assimilation is a major component of NWP. But contrast the state of this NWP article (very good) and the DA article (distinctly less good). Could some of the NWP-knowledgable editors turn their attention to the DA article, please? Feline Hymnic ( talk) 00:19, 19 October 2013 (UTC)
/there are some semantic issues though/
The probability of the occurrence of a weather phenomenon (e.g. precipitation)
is the expected value (of that phenomenon occurring)
of a large number of virtual outcomes,
for certain periods of time (quanta of time)
and the amount of a specific measurable effect of that weather phenomenon (over a threshold)
over each unit of time. — Preceding
