Australian Catagory Colour
[edit]I felt that the Australian System should have their own colours. I decided to have a play around and this is what i came up with. Tell me what you think.
Australian Category[1] | Maximum wind gusts (km/h) | Maximum sustained winds (km/h)[2] | Corresponding Beaufort Force[3] |
---|---|---|---|
Effects[4] | |||
Tropical Low | ≤125 | 63-88 | Gale (8-9) |
Negligible house damage. Damage to some crops, trees and caravans. | |||
Category 1
Tropical Cyclone |
≤125 | 63-88 | Gale (8-9) |
Negligible house damage. Damage to some crops, trees and caravans. | |||
Category 2
Tropical Cyclone |
125-169 | 89-117 | Storm (10-11) |
Minor house damage. Significant damage to signs, trees and caravans. Heavy damage to some crops. Risk of power failure. Small craft may break moorings. | |||
Category 3
Severe Topical Cyclone |
170-224 | 118-159 | Hurricane (12) |
Some roof and structural damage. Some caravans destroyed. Power failures likely. | |||
Category 4
Severe Topical Cyclone |
225-279 | 160-199 | Hurricane (12) |
Significant structural damage. Many caravans destroyed and blown away. Dangerous airborne debris. Widespread power failures. | |||
Category 5
Severe Topical Cyclone |
≥280 | ≥200 | Hurricane (12) |
Extremely dangerous with widespread destruction. |

No. Just no. We don't particularly need this at all. You tried your best, nonetheless. ~ AC5230 (talk) 03:25, 21 December 2019 (UTC)
Beaufort scale is off
[edit]According to all sources about the Beaufort scale (for instance https://www.rmets.org/weather-and-climate/observing/beaufort-scale), the scale is off in the Tropical cyclone classifications table. This should be the correct table:
![](http://upload.wikimedia.org/wikipedia/commons/e/eb/Beaufort_correct.png)
As can be seen there is an overlap between a category 1 hurricane (saffir simpson scale) and 11 beaufort.
They are wrong because the beaufort scale corresponds to the 10-minute wind speed. Currently in the table the 1-minute wind speed is used to assign the beaufort scale. The 10-minute beaufort scale should be used.
CDPS scale?
[edit]Where's the CDPS scale, created 2016 by Devon Williams? I'd like an explanation of it. 108.160.124.180 (talk) 18:03, 22 September 2018 (UTC)
- @Jasper Deng: My feeling is that the scale would fall under WP:Fancruft, since it's not been mentioned in reliable sources and was created by Force13. However, I would like a second opinion pleaseJason Rees (talk) 23:05, 22 September 2018 (UTC)
- Literally nothing on it found by Googling. Doesn't seem like any reliable sources wrote about it. So I agree, we shouldn't put it in.--Jasper Deng (talk) 01:45, 23 September 2018 (UTC)
- Also assessing the same as Jasper Deng. The scale is not used in any regular capacity outside of a niche group of a tropical cyclone enthusiasts. It is well below the significance threshold of the other scales featured on the article, which are either used officially by meteorological centers or have received widespread and verifiable media coverage or reliable journal publication.

- Also; I dunno how the heck F13 ranks CDPS compared to these other scales... ...so it wouldn't work much anyway (IMO).

Wind speeds converted incorrectly
[edit]Some numbers in the master table are converted incorrectly with Wikipedia's convert function. See discussion at Template_talk:Tropical_Cyclone_Classification Weathermatrix (talk) 15:27, 6 December 2019 (UTC)
Categorization of JMA scale in comparison table
[edit]The categories Very Strong Typhoon and Violent Typhoon on the JMA scale shown on the bottom scale comparison table do not seemingly exist. Those categories are not shown on the scale chart in the JMA scale's section of the TC scales WP page and no other known source talks about these categories on the JMA scale. The categories have been on there for months. Is there need for concern regarding this?

[edit]If the windspeed weakens in tropical storm,what will be it's new category? 49.145.54.151 (talk) 23:44, 8 December 2021 (UTC)
Scale coloring
[edit]I've noticed that the scale coloring has changed. What happened? If there's already something about this, I'd liked to know. Thanks. Mobius Gerig (talk) 04:03, 20 March 2022 (UTC)
- Hi, @Mobius Gerig, see Wikipedia talk:WikiProject Weather § RfC: Changing the color scheme for storm colors to make it more accessible, and the new scale's ensuing criticism at Wikipedia talk:WikiProject Weather § Comments. Chlod (say hi!) 14:43, 20 March 2022 (UTC)
FYI Template:Tropical cyclone classification (edit | talk | history | links | watch | logs) has been nominated for discussion at TfD. See the consensus-seeking discussion -- 65.92.246.142 (talk) 14:35, 20 March 2022 (UTC)
comparisons across basins
[edit]Why 'Comparision across basins' section is deleted?? 116.73.134.216 (talk) 17:31, 30 March 2022 (UTC)
- The section was deleted in a discussion as after numerous complaints, it was felt that the data could not be made, to be as accurate as it needed to be.Jason Rees (talk) 22:35, 30 March 2022 (UTC)
Australia and Fiji Section inaccuracy
[edit]According to the latest BoM update for a system (archived link), the system was a tropical low with sustained winds of 65 km/h. Per the scale in the article, that would be a category 1 cyclone, however, BoM marks it still as a “Tropical Low”. Scale is inaccurate per BoM. Elijahandskip (talk) 07:05, 10 April 2023 (UTC)
- @Elijahandskip: You clearly have not read Australian region tropical cyclone which says "Within this region a tropical disturbance is classified as a tropical cyclone when it has 10-minute sustained wind speeds of at least 65 km/h (40 mph) that wrap halfway around the low level circulation centre" (emphasis mine). So it is necessary, but not sufficient, for a tropical low to have gale-force winds for it to be upgraded to a tropical cyclone. I'm removing your disputed tag as being baseless; a clarification edit might be needed.--Jasper Deng (talk) 11:23, 10 April 2023 (UTC)
- @Jasper Deng:, I read that. My edit was about why the scale Template:Australian tropical cyclone intensity scale, says category 1 starts at 63 km/h. How is that not counter-productive? The article says a tropical low starts at 65 km/h, but the scale template says a category 1 cyclone starts at 63 km/h? That is the issue. The article point blank disagrees with itself. Elijahandskip (talk) 14:47, 10 April 2023 (UTC)
- @Elijahandskip: Read the section again and you will find that it says that Tropical Low is below 63 km/h or 35 kts. The article also says that the gale force winds need to be near the centre before it is named because that's the requirement for the majority of the warning centres in RA V. Australia (BoM) is the only exception to this rule. Jason Rees (talk) 20:08, 10 April 2023 (UTC)
