Category: Cloud-to-cloud lightning

How did you infer it for File:120516-N-UM734-1066 (7243619354).jpg? Incnis Mrsi (talk) 17:13, 9 February 2018 (UTC)

• @Incnis Mrsi: Well:

• There is no indication that the lightning is touching the surface of the sea. So it cannot be cloud-to-ground.
• The source is somehere above the ship structure but is not visible as one can juge by the brightness there and the branching of the lightning to the left.
• One can see that the lightning extend well beyond the generating cloud laterally too. So it cannot be in-cloud lightning.
• The description of the image says that the lightning is "over the amphibious assault ship USS Kearsarge".

Unless you have more information than the image can provide, cloud-to-clouds is the best that can be inferred.

Pierre cb (talk) 18:21, 9 February 2018 (UTC)

The surface of the sea? Should it, really, if the ship itself is a decent conductor? Incnis Mrsi (talk) 18:23, 9 February 2018 (UTC)

• @Incnis Mrsi: This has nothing to do with the conducting property of the ship (which are good) compared to the sea. The lightning is clearly heading away from the ship: look at the branches that diverge toward the left. There is no indication that the ship was touched in the description ... "over the amphibious assault ship USS Kearsarge". Pierre cb (talk) 18:29, 9 February 2018 (UTC)

Unsure what means you are in meteorology, but “lightning is heading away” is not a serious description. A lightning connects two spatial regions having a high voltage between them. It may have branches, and some of them have direction far from vertical (look at File:CG lightning strike.JPG for example). The “branches that diverge toward the left” lead to a cloud under a high voltage. The other end of the lightning is obscured by interposing ship structures and may lie out of the frame even if the lightning strikes the ship. Conducting properties of the ship, indeed, are very important because a lightning strike doesn’t cause significant damage, or even observable effects, on thick metal-grade conductors (unlike such materials as carbon fibre). Hence, I suggest to leave the navy image in Lightning although will not wage a war over it. Incnis Mrsi (talk) 19:12, 9 February 2018 (UTC)

@Incnis Mrsi: The category "Lightning" is a mother category and should be kept empty, all images transferred toward sub-categories, otherwise it will be overflowing in no time. You may not like my vocabulary but it is adapted to the description, maybe would have like that I use "leads" instead of "branches" but I will not rewrite here all the theory of lightning propagation. Cloud-to-cloud category is the best with the indications available on the photo, as I said in my first intervention. One cannot deduce more than the image shows and its description says. Pierre cb (talk) 20:00, 9 February 2018 (UTC)

The Lake Champlain - Richelieu River map

This map is inaccurate. Richelieu River is indeed finishing at Sorel but further North, in front of an island where the St Lawrence River is getting larger to become Lake St. Peter. Richelieu River is not turning left but going further North where Sorel is really located.

Important message for file movers

A community discussion has been closed where the consensus was to grant all file movers the suppressredirect user right. This will allow file movers to not leave behind a redirect when moving files and instead automatically have the original file name deleted. Policy never requires you to suppress the redirect, suppression of redirects is entirely optional.

Possible acceptable uses of this ability:

• To move recently uploaded files with an obvious error in the file name where that error would not be a reasonable redirect. For example: moving "Sheep in a tree.jpg" to "Squirrel in a tree.jpg" when the image does in fact depict a squirrel.
• To perform file name swaps.
• When the original file name contains vandalism. (File renaming criterion #5)

Please note, this ability should be used only in certain circumstances and only if you are absolutely sure that it is not going to break the display of the file on any project. Redirects should never be suppressed if the file is in use on any project. When in doubt, leave a redirect. If you forget to suppress the redirect in case of file name vandalism or you are not fully certain if the original file name is actually vandalism, leave a redirect and tag the redirect for speedy deletion per G2.

The malicious or reckless breaking of file links via the suppressredirect user right is considered an abuse of the file mover right and is grounds for immediate revocation of that right. This message serves as both a notice that you have this right and as an official warning. Questions regarding this right should be directed to administrators. --Majora (talk) 21:36, 7 November 2019 (UTC)

File:2019-12-30 16 43 08 Cumulus clouds during sunset along Tranquility Court in the Franklin Farm section of Oak Hill, Fairfax County, Virginia.jpg

It is impossible to see what clouds species is in this image, or the 4 others that I remove Category:Cumulus clouds (only partial vue). Furthermore, this category is a mother category and any images must be redistributed in its subcategories (see {{Categorize}}). I originally moved them to the location category of the name but you did not like it, so please don't not reverse me again.

Pierre cb (talk) 00:37, 1 January 2020 (UTC)

In case you hadn't noticed, the others you placed in congestus are from the same day and litterally a few minutes later, and in fact had just passed overhead. Famartin (talk) 02:15, 1 January 2020 (UTC)

• @Famartin: Yes, the others are showing at least TCU, I even hesitated to put cumulunimbus calvus. However on those 5 I cannot see any features associable to cumulus yet, just a hole in clouds of no special features. In the other pictures, one can see the TCU emerge thru the hole but not in those 5. Pierre cb (talk) 05:35, 1 January 2020 (UTC)

@Pierre cb: The category is "cumulus congestus clouds". Not "cumulus congestus clouds clearly identifiable in photography". I identified them as cumulus, and you clearly decided that these same clouds, visible later from a different angle, were congestus. So that's where they go. Famartin (talk) 05:52, 1 January 2020 (UTC)

@Famartin: You mislead the viewers. Looking at those 5 pictures, they will identify featureless clouds TCU. What is the most important for the viewer : a picture that shows the characteristics to identify a type of clouds or misleading them? Pierre cb (talk) 05:58, 1 January 2020 (UTC)

@Pierre cb: I think the file name and caption makes this more obvious now. If you really feel strongly, I suggest you do one of the following: Create 'Category:Cumulus congestus in the United States (partial)' or 'Category:Cumulus congestus in the United States (incidental)' for files such as these.

Jet Stream diagram.svg

Bonjour Pierre,some years ago you created Jet Stream diagram es.svg and Jet Stream diagram es.svg, thank you. There seems an translation error to have occurred, at the conversion from miles to kilometres. I am not at all the professional as you, I do not know the length of the jetstream. But the original said "3000 miles", which will not be 9000 km. I added to the original File:Jet Stream diagram.svg the French and Spain translation both with 5000 km. I changed also the usage of both your files to the original version.
If this number is not correct, it should be maintained in the original file!
When you agree that it will be the best, you may request deletion of your both now unused files? Cdlt -- sarang♥사랑 08:32, 2 February 2020 (UTC)

@Sarang: It seems I was in the clouds when I made the SVG as my png versions are saying 5000 km. I probably made a second conversion. However, a jet-stream can be much longer than 3000 miles, in fact it can go around the globe, so it is not such a bad error. How do it proceed to delete the 2 images in error? Pierre cb (talk) 14:42, 2 February 2020 (UTC)

Hi. It is always better to have one multilinual version, than different national files. Of course, the multi file should have at least the quality of the single-language file. I can make the delete request, if you do not know how.

It will not be a problem to change the text to e.g. "...5000, or 11000 km..." or somethng like that, if this will give a better information. Everbody with a bit text-editing knowledge can change embedded text, luckily all your SVG files use this feature. But I can change it very swift, when you tell me which milage you prefere.

BTW, to be in the clouds is not at all bad for a meteorologist.... cdlt -- sarang♥사랑 15:37, 2 February 2020 (UTC)

@Sarang: You have my blessing to ask for the deletion of my SVG. They are not in use anymore, anyway. Pierre cb (talk) 22:30, 2 February 2020 (UTC)

cat change

Just curious about this category change] you made. As far as I know the image was not manipulated, the National Park Service usually doesn't doctor publicly released images. Beeblebrox (talk) 19:53, 13 September 2020 (UTC)

@Beeblebrox: Category:Rainbows is a mother category and all images should be transferred to relevant sub-categories. In the case of this image, it seemed to me it was the most relevant as the whole photo seems like an artistic view and I could not find the country in order to move to "Category in XXXX". If you know the correct subcategory to use, please modify my edition. Pierre cb (talk) 21:15, 13 September 2020 (UTC)

File:Early morning rainbow.jpg

Hi! You moved this file with the reason "Name without User's ID". First that is not a valid reason and second when you did not create a redirect and cleaned up after you on Japanese Wikipedia you leave work for other users. ALWAYS leave redirects and make sure you follow rename policy and that you clean up thank you. --MGA73 (talk) 09:32, 17 October 2020 (UTC)

@MGA73: Sorry about the renaming comment which was confusing. It was supposed to means that a file should not have the name of the uploader in it. As for not leaving a redirection, I don't remember doing that but you are right about this point. Pierre cb (talk) 15:27, 17 October 2020 (UTC)

File:3D-radar fr.svg

Hallo - shouldn't we use more detailed version as source for the svg-version? Or isn't this diagram even better? -- MaxxL - talk 16:22, 3 October 2020 (UTC)

Another idea: we take as source this PNG and add the French text only while we drop/delete the SVG. Your opinion? -- MaxxL - talk 17:00, 3 October 2020 (UTC)

Meanwhile there is a provisional SVG of 3D Radar beam ready. Have a look and post your comment here. -- MaxxL - talk 21:58, 3 October 2020 (UTC)

@MaxxL: If you look carefully 3D-radar fr.svg is an SVG from File:3d-radarp.jpg which just is a different version of 3D-radar.png you mentioned in your latter suggestion. I do not understand what is the difference to input a PNG over a JPEG to make a SVG but I guess it would be the best solution. Pierre cb (talk) 22:10, 3 October 2020 (UTC)

Good idea. Just insert the French wording in the PNG and you are done. -- MaxxL - talk 22:16, 3 October 2020 (UTC)

@MaxxL: I uploaded a new version using the png. Since I did not make a proper SVG the first time, could you do verify it and correct the info about the validity of the SVG? Pierre cb (talk) 03:38, 4 October 2020 (UTC)

@MaxxL: Can you validate my changes? Pierre cb (talk) 12:18, 4 October 2020 (UTC)

No, I can't. The same mistake as before: you just inserted the PNG and added only two vector text lines to it. This way it a "wrapper" or fake SVG, une SVG cachée. Why don't you simply add the two text lines to the PNG using GIMP and enjoy the same - if not a better - image quality? Every SVG image is rendered/converted to PNG in Wikipedia by the "librsvg" anyway. Didn't you know that? - MaxxL - talk 12:41, 4 October 2020 (UTC)

@MaxxL: Sorry, I have a limited knowledge of the process. As far as I know, text should be inputted in SVG over a graphic in order to have the possibility of multiple languages. I do not understand why I should make a fix PNG with permanent text and import it into an SVG format. You are better to do the correct procedure because I cannot go further as it goes against all I know. Pierre cb (talk) 23:18, 4 October 2020 (UTC)

What type of radar

Hi Pierre cb. I have seen that you changed the category from "Radars" to "Speed camera signs in Poland". From the description I conclude that it is not a speed camera but a device for Traffic flow measurement. A have seen a similar device in Belgium and the people who have installed it told me that is was to measure the traffic flow. Pedestrians, cyclists, automobiles and trucks. It was there for about two weeks. I asked in the Villagepump about this for the best categories. May be you know a better category. Wouter (talk) 14:18, 22 April 2021 (UTC)

@Wouterhagens: I had doubt when I did the change by reading the definition. However, I was not sure and I have put what seemed the closest. With your explanation, you could simply remove the "Speed camera" category altogether. It has already Category:Road traffic control and it should be enough. Pierre cb (talk) 15:51, 22 April 2021 (UTC)

Thanks. I did what you suggested. Wouter (talk) 16:18, 22 April 2021 (UTC)

Merci pour tes apports en matière de Catégories

Merci, cher Pierre cb, pour tes apports. Le problème des catégories est un problème important et nécessite un peu d'habitude. Mais ne crois-tu pas que le dernier diagramme que j'ai publié File:Vitesse_terminale_des_gouttes_d'eau_de_diamètre_inférieur_à_1mm.png) mérite d'âtre signalé aux gens qui s'intéressent au régime de Stokes, ainsi qu'aux gouttes d'eau, en général ? Amicalement, Bernard de Go Mars (talk) 17:06, 16 January 2022 (UTC)

@Bernard de Go Mars: Excuse-moi, j'ai enlevé la catégorie de Stokes par erreur et je viens de la remettre. Pour ce qui est des gouttes de pluie, j'ai mis le diagramme dans Category:Diagrams depicting rain. Si tu veux, je pourrais créer une sous-catégorie Category:Terminal velocity of raindrops reliée à la précédente et à Category:Terminal velocity? Pierre cb (talk) 19:18, 16 January 2022 (UTC)

Merci pour ces éclaircissements. j'ai remis aussi la catégorie Drag, car pour les météores en général la traînée est une grande inconnue (il s'avère, c'est bizarre, que presque la moitié des fichiers de cette catégorie vient de mon ordi)...

La création d'une nouvelle catégorie "Terminal velocity of raindrops" serait intéressante, mais serait plus utile si elle s'appelait "Terminal velocity of meteors" ou quelque chose comme ça, car pour les gouttes d'eau le problème est plus simple. C'est pour les grêlons et la neige que le problème est plus complexe, pour ce que j'en sais.

Ce que j'aimerai, à propos de météores, ce serait réaliser une animation de l'éclatement d'une grosse goutte pour illustrer le fait qu'il n'y a pas de goutte de diamètre (équivalent) > 5 ou 6mm. Mais le dessin de ce phénomène est assez difficile et mon artiste préféré, qui aurait pu m'aider, a des problème d'ordinateur... Amicalement, Bernard de Go Mars (talk) 21:10, 16 January 2022 (UTC)

@Bernard de Go Mars: Ça serait plutôt « Category:Terminal velocity of precipitation » car « Category:Terminal velocity of hydrometeors » incluraient la brume et les nuage et « meteor » inclut les météorites. Je viens de faire la création. Pierre cb (talk) 23:14, 16 January 2022 (UTC)

D'accord pour "hydrometeore" pour ne pas prendre en compte les cailloux du ciel ! Mais par contre, les brumes, crachins et autres formations formées d'eau sont des précipitations comme les autres et relèvent des mêmes calculs... Ceci posé "precipitation" équivaut à "hydrométéore", même si les poussières volcaniques et les sables du désert sont sans doute à y placer... Amicalement, Bernard de Go Mars (talk) 16:12, 17 January 2022 (UTC)

Merci pour la création de la catégorie "Terminal velocity of precipitation". Comme tu le sais, ce problème est très important en météo.

Par contre, j'ai réattribué la catégorie "Drag" à ma dernière publication car il s'agit bien de Traînée et cette entrée dans l'univers des hydrométéores peut être utile. J'en ai profité pour radier nos camarades drag queens de la catégorie "Drag".

J'y pense : Je suis en train de préparer une nouvelle version de l'article "Forme d'une goutte de pluie" (lire la PdD de cet article). La nouvelle version figure dans le haut de ma page de brouillon. Cette nouvelle version s'avère assez complexe (comme les phénomènes physiques qui sont en jeu) et trop peu de contributeurs s'intéressent à la Mécanique des Fluides et à la Physique des hydrométéores. Amicalement, Bernard de Go Mars (talk) 09:09, 25 January 2022 (UTC)

@Bernard de Go Mars: Ne trouves-tu pas que Category:Drag (fluid dynamics) que tu as rajouté est redondant avec Category:Lift and drag dont il est une sous-category. A mon avis, il faudrait choisir l'une ou l'autre catégories. Pierre cb (talk) 14:00, 25 January 2022 (UTC)

Je comprends la question.

• Un façon d'y répondre est d'évoquer le coût de la mention d'une catégorie dans la page de définition : quelques signes. Il s'agit, avec la mention de ces catégories de faire la publicité aux autres fichiers du même ordre et cette publicité gagne à se faire, à mon sens, avec des redondances (par exemple la redondance de "Fluid mechanics" ou mieux de "Fluid mechanics in the 20th century"). Ces redondances sont des ouvertures : on les lit, et on les choisit ou non ; c'est pratique.
• Personnellement, j'ai du mal à me servir des sous-catégories, je trouve ça compliqué (bien que je ne sois pas contre, évidemment). Je préfère quand s'ouvre un ensemble de fichiers images.
• Attention au fait qu'actuellement "Lift and drag" ne comporte pas la sous-catégorie "Drag". Tu peux donc la créer.

Je viens d'ajouter le courbe standard du Cx selon le Re,pour les sphères rigides dans mon dernier graphe.

Amicalement, Bernard de Go Mars (talk) 17:23, 25 January 2022 (UTC)

@Bernard de Go Mars: Je comprend ton idée mais ça mène à un fourre-tout. Par exemple, il y avait des milliers de photos dans la Category:Clouds avant que je l'élage. Comment pouvait-on retrouver une image dans un tel fouillis. C'est la même chose avec tes ajouts, il est mieux de mettre dans une sous-catégorie qui elle peut être reliée à plusieurs catégories associées. Pierre cb (talk) 17:50, 25 January 2022 (UTC)

Oui, c'est un problème difficile et j'ignore la politique en cours sur ce sujet. Pour ma part, je dirais que mes images qui concernent la traînée sont à placer dans "Drag", mais si cette catégorie est une sous-catégorie de "Drag and lift", ce n'est pas gênant. C'est sûr que la catégorie "Fluid mechanics" doit être encombrée et qu'il vaut mieux la scinder en sous-catégorie. Amicalement, ~~ Bernard de Go Mars (talk) 21:37, 25 January 2022 (UTC)

Category renaming

Hi, Pierre cb. Please, don't do that. That one is a "text category". That is, a category trying to group trying to group images depicting a specific text string. In that case, that string was "derechos humanos". Similarly, don't rename those categories from German to English please, and neither these ones. If you have a problem with a particular category, please open a "category for discussion" process. Strakhov (talk) 06:17, 1 October 2022 (UTC)

@Strakhov: This lead to confusion as what you are talking about is related to « Category:Law » while Category:Derechos in a weather phenomenon. Please remove immediately Category:Derechos (text) from Category:Derechos. Pierre cb (talk) 11:29, 1 October 2022 (UTC)

Hi, Pierre_cb. It's sad but it is not possible to remove that category while using {{Text cat}} as far as I know. It's an automatic category added by that template (when it exists a category with the same name minus the "(text)" the parent category is included). You can either: 1) remove {{Text cat}} from Category:Derechos (text), 2) move Category:Derechos to Category:Derechos (weather phenomenon) or 3) edit the template {{Text cat}} to add an option to opt out from that automatic categorisation (I do not know how to do that). And by the way, no, "Derechos" in Spanish does not mean "Law" (that would be in singular ("Derecho"), asides "Ley") but "Rights". Cheers. Strakhov (talk) 15:25, 1 October 2022 (UTC)

@Strakhov: Since categories in Commons are usually in English and Category:Derechos is way older than your Derechos (text). I am against your second option. I see that you have already modified with option 1 and I approve. If you want to use the third option with text=Rights in {{Text cat}} that seems possible, too.

Mass Category reversions

Hello. I am wanting to know why you reverted over a dozen category additions I did to Category:Weather of 2023. On Wikipedia, any article relating to weather during the year 2023 is added to the Category:2023 meteorology, so why is ever weather-related image during 2023 not allowed to be grouped into a similar category on the commons? Elijahandskip (talk) 21:36, 26 January 2023 (UTC)

@Elijahandskip: All I did is to eliminate the redundancies your category create in Commons:

1. The right category for all your images is Category:Weather in 2023 that already exits and follow similar categories created by others for previous years.
2. Furthermore, all the images you have put in your "Category:Weather of 2023" are already contained as sub-categories of Category:Weather in 2023. For example, tropical cyclones, storms, etc...

Further info, I proceeded to an elimination of redundancy as Category:Tornado outbreak of January 12, 2023 is sub-category of Category:Tornadoes of 2023 and an image should not be in both, only the more direct sub-category.

How to ask for speedy-delete of an empty category

When you want to ask for speedy-delete of an empty category, best practice is to mark it with {{SD|C2}} if it would be OK to re-create it in the future, given that appropriate content becomes available or {{SD|C1}} if it is an inappropriate category name that should not be reused. In particular, this is better practice than just blanking the category page, as you did at Category:Tropical Depression 05 (2024). ("C1" and "C2" come from Commons:Criteria for speedy deletion).

RfC: Third-party images published by the National Weather Service

I've now reviewed 1,000 images uploaded under the rationales expressed in the {{PD-NWS}} template and requested deletion of several.

The arguments for deletion, and to keep, are now following repetitive, predictable patterns and it would greatly help all involved if we could centralise discussion and obtain some wider community input.

Therefore, I have opened an RfC to gather opinions. Apologies in advance: it's long and detailed, but is frankly nothing compared to the words and time expended by all parties up to this point. Probably the most crucial issue revolves around how we interpret a general disclaimer published at weather.gov (Q.1 in the RfC).

Your advice is greatly appreciated! --Rlandmann (talk) 10:41, 26 August 2024 (UTC)
