Talk:Weather radar

message: Bravo to the editors of this article.  I hope someone meeting the criteria can nominate this article for Wikipedia:Featured article candidates.
I have a lay understanding on the subject matter as an Air Force Veteran but I am far from a subject matter expert, and was thrilled to see an article balance the science and math so well without making the article completely unapproachable to the rest of us.
It seems that so many science articles get hijacked by subject matter experts who transform the article into a post-graduate level thesis, and which can only be understood by their academic or professional peers.  These contributors often scoff at criticisms that their articles need to be made more approachable to the everyday user.
This article on the other hand appears to be very comprehensive, sacrificing none of the science while making it a joy to read for those seeking every day knowledge on a matter that affects all of our lives. Tolstoy143 - "Quos vult perdere dementat" (talk) 13:12, 28 January 2009 (UTC)

replies: text: We had the same problem in the extratropical cyclone article.  I'd mention a simple description of the technical terms, when and where they are first used.  Thegreatdr 23:59, 9 December 2006 (UTC)
replies: text: Well, the problem comes when technical terms aren't explained, and compounded when poor writing confuses even technical readers.  I'm working on fixing these kinds of problems with this article; I'll ask some particular technical questions so we can clear things up. -- Beland 02:51, 2 January 2007 (UTC)
thread_title:  To do 

message: What frequencies bands do weather radars use?  S-band links to this article, for example. -- Beland 22:12, 17 December 2006 (UTC)
replies: text: Weather radar uses wavelenghts that are typically 10 times the diameters of the targets in order to obey the Rayleight law. That means centimetric wavelengths and usually 1 to 10 cm. The shorter the wavenlength the more attenuation, so 10 cm (S-band) is favored but its cost is greater so 5 cm C-band is often used. 3 cm X-band is used only in very short distance radars and 1 cm Ka band (corrected from L-Band) only for research of drizzle and fog. All this is mentionned in the article, in particular in the "Principles of radar in meteorology" section. Pierre cb 04:48, 18 December 2006 (UTC)
replies: text: Interesting.  I'll add your explanation to the article.  Thanks! -- Beland 02:19, 2 January 2007 (UTC)
replies: text: In frequencies bands, L Band is between 15-30 cm not 1 cm.  — Preceding unsigned comment added by Jhawri (talk • contribs) 19:03, 5 February 2012 (UTC)
replies: text: Sorry, the old definition of the 1 cm wavelenght band was L-Band. It is now Ka band. I have corrected in the above comment. Pierre cb (talk) 04:44, 17 February 2012 (UTC)
thread_title: Frequencies

message: * It looks like the beam width "theta" is supposed to be the diameter of the cross-section of a beam which is assumed to be circular?  Is that an accurate assumption?
* Is the radius "r" supposed to be the calculated from the beginning, middle, or end of the pulse?  Is the h*r^2*theta^2 formula approximate or exact?
-- Beland 03:10, 2 January 2007 (UTC)
replies: text: The volume calculation is equivalent of calculating the volume of a slice of a think sphere skin. This is an approximation of the real volume at distance "r" from the radar since a real radar beam is very complexe and the volume is really a truncated cone, not a circular slice. le formula assume that "r^2 \theta^2" to be the area of the sphere intercepted by the angle \theta from one side to the other of the beam center where energy falls by half. "r" is usually taken at a distance where r>>h. Since h is about 200 meters in weather radars, "r" can be using beginning, middle or end of pulse distance with little difference if at 10 km of more. I will add information on that in the text. Pierre cb 02:03, 12 April 2007 (UTC)

message: ...but it will get more attention both within wikipedia and the meteorology project if it achieves GA.  We can't begin to consider it for GA without inline references, roughly one per paragraph or important fact, regardless of content.  Make it so, and it will be nominated.  Right now, it wouldn't have enough references to pass. Thegreatdr 14:56, 22 June 2007 (UTC)

thread_title:  Urban Spike? 

message: I don't think that dual polarization helped as much as the news article claimed, but that the author saw that the radar was recently upgraded and came to the conclusion that the upgrade helped a lot. Dual polarization is only really useful in finding a TDS, but by that time it's too late to issue a timely warning. What do you guys think? Michael73072 (talk) 12:41, 1 March 2014 (UTC)
replies: text: I agree with you, dual polarization is much more important for precipitation types (snow, rain, hail, etc...). When the tornado debris are dense enough to be seen on radar, the tornado has touch down for a while. I removed the comment in the article as it is not a NOAA claim.

message: Hello fellow Wikipedians,
I have just added archive links to  on Weather radar. Please take a moment to review my edit. You may add  after the link to keep me from modifying it, if I keep adding bad data, but formatting bugs should be reported instead. Alternatively, you can add  to keep me off the page altogether, but should be used as a last resort. I made the following changes:

thread_title:  External links modified (January 2018) 

message: I work in the radio spectrum management field in Canada. Over the years I have worked on a number of investigations into radio interference to weather radar systems. I have some images, gif sequences and maybe a video or two of how these effects manifest themselves on weather radar images found on Env. Canada's public web pages and a private company's web page. I'm fairly knowledgeable about how outside radio systems can affect weather radar and wish to contribute, but I would definitely need editorial help. This is all under the condition that the author of this article wishes to view or have the information. Let me know if you are interested.Bewernia (talk) 19:52, 21 February 2018 (UTC)

message: * AGAINST: The DBZ article is for the unit of reflectivity while the section in Weather radar is for the principle of reflectivty, two independant concepts. Furthermore there both have independant interwiki and article that links there. Pierre cb (talk) 13:45, 2 August 2020 (UTC)
