[edit] test for me

P_r = \left [ P_t{{ G^2 \lambda^2 \sigma^0}\over{{(4\pi)}^3 R^4}} \right ] \propto \frac {\sigma^0} {R^4}\qquad \qquad \begin{cases} P_r = received\ power \\ P_t = transmitted\ power \\ G_t = gain\ of\ the\ transmitting\ antenna \\ \lambda = radar\ wavelenght \\ \sigma = radar\ cross\ section\ of\ the\ target \\ R = distance\ from\ the\ transmitter\ to\ the\ target \end{cases}

[edit] Picture categories

Pierre, you picture was attached to main meteorology category. If you would like to use it - the best way would be to add it to radar meteorology article? Otherwise we would have hundreds of pictures attached to "meteorology" (not only radar but clouds, etc) Pflatau 15:00, 23 May 2006 (UTC)

In general, pictures on Wikipedia should not be placed in categories. The category system doesn't handle them well. Pictures on Wikipedia should be added to articles, where appropriate. If the goal is to make the picture itself available to the public (as opposed to using it to illustrate any particular article), the picture should instead be uploaded to the Wikimedia Commons [1]. Pictures there can be linked to from Wikipedia articles just as easily as pictures that are actually on Wikipedia, and the Commons' categories are for pictures and other media.--Srleffler 16:05, 23 May 2006 (UTC)

[edit] WKR

I've moved the article to CWKR, per your request and based on various websites (eg - [2] [3]). However, Environment Canada seems to list its own ID for radar sites (see this). Should this be of concern? Mindmatrix 17:24, 14 June 2006 (UTC)

[edit] Ceilometer

I saw this popup in my watchlist and actually read the article. Cna you look at this (2nd last paragraph) and make sure I fixed it correctly. They took ours away and we no longer have the manuals for me to check. Thanks. CambridgeBayWeather (Talk) 09:00, 25 June 2006 (UTC)

Thanks. I didn't know it was you as the anon. CHeers. CambridgeBayWeather (Talk) 12:22, 25 June 2006 (UTC)

[edit] Lightning detector

Thanks for adding the diagrams, Pierre — they look great. I reorganized the text in that section and bit, and would be grateful if you could read it over to make sure I haven't introduced any errors. David 17:54, 6 July 2006 (UTC)

[edit] Image:Freezing rain.png

Question: Why did you put a NO SOURCE on Image:Freezing rain.png when is is clearly marked that it is from ENVIRONMENT CANADA which allow reproduction if source mentionned? Pierre cb 01:16, 16 August 2006 (UTC)

It has no web reference to where it was found. // Liftarn

[edit] Image:Freezing rain.png

Hi,

Image:Freezing rain.png
300px

Your bot removed this image saying it is without source. However, the description is CLEARLY showing that the image is from Environment Canada. As a canadian goverment departement they allow reproduction (see their site). So could you put back this image!

Pierre cb 23:10, 15 August 2006 (UTC)

They may permit reproduction, but that is not the same thing as an any-purpose license. See User:Carnildo/Image FAQ section 1.2. --Carnildo 07:23, 16 August 2006 (UTC)

[edit] Your comments on Wikipedia talk:WikiProject Meteorology

I'm a little confused as to what you are asking. Right now we have a lot of articles about instrumentation and stuff like that (mostly listed in subcategories of Category:Meteorology). Eventually all articles relating to meteorology will be listed here, but this will probably take awhile. -Runningonbrains 06:13, 13 September 2006 (UTC)

[edit] Weather Radar

Hi,

In the radar article you have changed the caption to "Storm front on Doppler radar screen (NOAA)". This is not a Doppler radar display (velocity) but a reflectivity (intensity of precipitation). It is an american media error to subtitute Doppler to Weather radar. Weather radar can be Doppler but a Doppler radar is not necessarily a weather radar. Sorry but I have to correct. Pierre cb 13:27, 29 March 2007 (UTC)

I agree with you on your point that a weather radar can be Doppler, but not necessarily. I was not trying to imply that this was a Doppler image, otherwise I would have said "Storm front on radar's Doppler screen". Rather, I was pointing out the fact that the radar screen belongs to the Doppler radar. Actually, I just did a direct translation of the image file name from German. To prove to you that the radar is indeed a Doppler radar, I'll show you the source of the image, whose caption states it is the "Norman Doppler radar reflectivity display showing squall line." In my haste, I removed the word reflectivity, thinking that the average reader would not understand, but that has obviously caused confusion. Can we change the caption to read:
"NOAA's Norman Doppler radar reflectivity (precipitation intensity) display showing squall line"
or something to that effect? —Gintar77 23:43, 29 March 2007 (UTC)

No problem. They seem to have stopped for now. CambridgeBayWeather (Talk) 11:57, 16 April 2007 (UTC)

[edit] Radar FAR

Radar has been nominated for a featured article review. Articles are typically reviewed for two weeks. Please leave your comments and help us to return the article to featured quality. If concerns are not addressed during the review period, articles are moved onto the Featured Article Removal Candidates list for a further period, where editors may declare "Keep" or "Remove" the article from featured status. The instructions for the review process are here. Reviewers' concerns are here. SandyGeorgia (Talk) 23:03, 9 July 2007 (UTC)

Hi, Pierre; we routinely notify the top editors, and you're on that list.[4] Regards, SandyGeorgia (Talk) 14:10, 10 July 2007 (UTC)

[edit] Proposed deletion of tornadocane

I saw you edited the article recently, so I'm leaving a comment here on your talk page. A similar article, landphoon, was deleted from wikipedia despite having seven unique references. Tornadocane has one. Neither term (including landcane) exists in the glossary of meteorology, so it can be delisted as not being encyclopedaic. Also, the meteorology community doesn't even use the tornadocane term, though landphoon and landcane come up from time to time. I hadn't heard of the term before going to Roger Edwards' page on the 1999 event quite recently, where he appeared to coin it. Thegreatdr (talk) 16:44, 9 February 2008 (UTC)

Even if I merged material from the landphoon article, the tornadocane article would be deleted for the same reason. The only country that mentions them at all is Australia, and even they don't even have a definition for the term. Right now, landphoon/landcane are only mentioned colloquially, with no actual definition other than "you know one when you see one." If there's no established definition in any primary source, including the Bureau of Meteorology (the aussie NWS), then it can't be listed in the wiktionary, let alone wikipedia.

[edit] Doppler radar vs. Doppler weather radar

While I suppose it is technically more correct to say Doppler weather radar, I have very rarely seen this phrasing use. You say that "Doppler radar" is a misnomer. It's not a misnomer, and especially not an "American" misnomer; it is accurate, it's just a shortening. It is the term used by the National Weather Service, The Weather Channel, The Australian Bureau of Meteorology, Environment Canada, and almost every other agency that I could find. In most contexts, it is clear that when an article uses the phrase Doppler radar they in fact mean weather radar with Doppler capabilities. I am going to be going through and clarifying wording in a bunch of the articles you changed, I hope you don't mind, but clearly, the phrase "Doppler radar" wins out over "Doppler weather radar" or, even worse, "Doppler effect weather radar". Let me know if you have any problems with this. -RunningOnBrains 21:16, 11 February 2008 (UTC)

I was not aware of that. Regardless, I will be leaving some links as plain weather radar, but the ones that are specifically doppler-based I will be changing to Doppler radar (written [[Pulse-Doppler radar|Doppler]] [[weather radar|radar]]). I think it's important to have a link to both topics, as well as using the familiar wording term which seems to be universally used in non-technical settings. -RunningOnBrains 21:39, 11 February 2008 (UTC)
I suppose. As I said, I wasn't aware of the difference, and so it seems you are mostly right. I'll try to avoid using the term "Doppler" at all if not necessary, and will only change the phrase to include both links where the doppler part is important, such as with discussion on Tornado vortex signatures. -RunningOnBrains 22:00, 11 February 2008 (UTC)

[edit] Category renaming

Hi, I've proposed that most of the subcategories you created under Category:Meteorological institutions and stations be renamed. You can discuss the nomination at Wikipedia:Categories for discussion/Log/2008 March 4 #Meteorological categories. Graham87 10:15, 4 March 2008 (UTC)

[edit] BWER

I figured out the mistake concerning Doppler in Canada soon after I made the change...which was 1985 not 1993. And you're right about BWERs...any radar should be able to capture them. My problem (and that of the GA reviewer) was that references were not provided for that line, and I could not find one on the internet. If your masters is such a reference, or you know of an appropriate text reference, readd the date wording, providing your master's or the appropriate paper/book as the reference.

[edit] North American ice storm of 1998 GA Sweeps Review: On Hold

As part of the WikiProject Good Articles, we're doing sweeps to go over all of the current GAs and see if they still meet the GA criteria and I'm specifically going over all of the "Meteorology and atmospheric sciences" articles. I have reviewed North American ice storm of 1998 and believe the article currently meets the majority of the criteria and should remain listed as a Good article. In reviewing the article, I have found there are some issues concerning sourcing that may need to be addressed, and I'll leave the article on hold for seven days for them to be fixed. I have left this message on your talk page since you have significantly edited the article (based on using this article history tool). Please consider helping address the several points that I listed on the talk page of the article, which shouldn't take too long to fix with the assistance of multiple editors. I have also left messages on the talk pages for other editors and related WikiProject to spread the workload around some. If you have any questions, let me know on my talk page and I'll get back to you as soon as I can. --Nehrams2020 (talk) 02:06, 17 March 2008 (UTC)

[edit] Tornado

I'd like to leave it for a few days and see how things develop. If you want to start a discussion about protection, you can try Talk:Tornado or WP:RFPP. Cheers, --Ryan Delaney talk 15:18, 18 March 2008 (UTC)
