Size

One measure of the size of atropical cyclone is determined by mesuring the distance from its center of outtermost closed isobar also known as its ROCI. If the radius is less then two degress of latitude —Preceding unsigned comment added by 216.162.29.62 (talk) 13:40, 7 May 2009 (UTC)[reply]

Other Names

Tropical Cyclones are referred to by a number of agencies as tropical revolving storms. Some example references I found from a quick google search:

Johnwalton 21:17, 16 May 2009 (UTC)[reply]

Not by any offical WMO RSMC/TCWC agencies which is what we keep it too. Jason Rees (talk) 21:49, 16 May 2009 (UTC)[reply]

I don't really understand why the article should be limited to what the WMO RSMC agencies refer to TCs as, when there are other names (such as tropical revolving storm) that are commonly used. By Wikipedia:Naming conflict: a Google search produces a large number of results for tropical revolving storm. At least one international organisation, ICAO (see above) refers, as well as a number of national organisations listed above (in addition to those above, the China Typhoon website also does). At least one major English-language media outlet, the BBC, the Telepgraph, other encyclopedias (Britannica, Encycopedia.com, OUP Dictionary of Ecology), and many scientific journals (three of which are referenced above), all describe hurricanes, cyclones etc as tropical revolving storms. Johnwalton 08:36, 17 May 2009 (UTC)[reply]
Actually the CMA uses Tropical and Severe Tropical Storm in their BT and theres no evidence to say they dont use these classifications operationally as per other NMHSS. The ICAO's are ussually prepared by the various RSMC's and TCWC's and thus they copy the classifications that the Warning center uses. Also most of those links suggest that a hurricane is a storm that is tropical and is revovling around which is correct. Jason Rees (talk) 16:25, 17 May 2009 (UTC)[reply]
Which is the point I was making, "tropical revolving storm" is another way to describe a tropical cyclone, and more accurate than simply "tropical storm". Johnwalton 12:43, 29 May 2009 (UTC)[reply]
No its not more accurate a Tropical storm is an offical designation and Tropical Revolving Storm is not and is not used by any of the NMHSS or RSMCs.Jason Rees (talk) 13:56, 29 May 2009 (UTC)[reply]
I read that more as a description than as a name, so I'm not sure those links apply... Titoxd(?!? - cool stuff) 02:57, 30 May 2009 (UTC)[reply]
I agree, they seem more like descriptions. I don't think we should add that, as the article already describes that tropical cyclones are spinny tropical things. ♬♩ Hurricanehink (talk) 03:07, 30 May 2009 (UTC)[reply]

Just a suggestion...

I find this a great article. What I think should be added is the fact that tropical cyclones don't only lose their strength from interaction with land. TC's lose strength also by moving over cooler water or when they pass through a new part of the ocean, where the upper level winds were not what they were when they gained their strength. It's something I've learned from years and years of following and studying hurricanes. Thanks24.187.138.123 (talk) 00:52, 1 June 2009 (UTC)[reply]
You could probably find that info in the "Factors" section. Cheers, –Juliancolton | Talk 01:14, 1 June 2009 (UTC)[reply]
Re-reading this section, it seems that some of my advice was taken. That makes me happy to be a small part of such a great article. Thanks!Popartpete 01:15, 15 June 2009 (UTC) —Preceding unsigned comment added by Popartpete (talk • contribs)

Removed "flooding rains"

Flooding is not a requirement for a tropical cyclone. Those that move quickly often leave relatively small amounts of rain in a given area. Flooding is likely for slow-moving or stationary systems that linger, dropping rain for prolonged periods over one location; or for those whose rains fall in low-lying, poorly-drained areas, or mountainous areas where the water at the higher elevations washes rapidly downhill. Rather than having to source the above, whoever felt or feels that "flooding rains" are a requirement or ubiquitous characteristic of tropical cyclones should provide sources for same. (It isn't, so you won't. Trust me, or waste your time.)

Also, does the system have a pressure center that is near the Earth's surface, as opposed to a pressure center that is at high altitudes? -- a "low pressure center" vs. a "high pressure center"? Of course not. It has a "low-pressure center", a center of low pressure, and that first ambiguity is exactly why compound modifiers should have hyphens. Main page needs to reflect both of the above. Unimaginative Username (talk) 05:06, 1 June 2009 (UTC)[reply]

Most tropical cyclones do produce flooding rains once they move inland (even fast moving ones). Only systems which are weakening appear not to. Also, tropical cyclones have a high pressure center aloft superimposed above a low pressure center at the surface. As for the hyphen thing, meteorologists tend not to place hyphens within the phrases of high pressure area and low pressure area. Is this correct? Perhaps not. Then again, wikipedia is supposed to reflect the most common term usage, not what is grammatically most correct. While there has been no effort to correct the titles of low-pressure area and high-pressure area to exclude the hyphens, one could make a strong case to exclude them, since they are rarely, if ever, used for these systems. Thegreatdr (talk) 08:43, 1 June 2009 (UTC)[reply]
WP MOS and the article linked, on compound modifiers, govern here. Meteorologists can write their own way, "correct" or not.
"Then again, wikipedia is supposed to reflect the most common term usage, not what is grammatically most correct." Excuse me, I thought this was an encyclopedia... which should exemplify best usage? ... I'm aware of where the pressure is, having had some meteorological training. It was a rhetorical question to illustrate the ambiguity and support the need for the hyphen. And what is your definition of "flooding"? My street flooding for a few hours? Happens in local afternoon thundershowers frequently. Widespread flooding of homes and cars? I'd like to see the statistics, but it doesn't matter. You said most, which backs up what I said, per the Black Swan principle: The production of flooding rains is not a requirement for a system to qualify as a tropical storm. Origin, rotation, strength, pressure gradients, etc. are; results are not. Hurricane Andrew leveled huge portions of areas south of Miami, Florida, USA, but moved so quickly that flooding was local and minor. Unimaginative Username (talk) 05:04, 2 June 2009 (UTC)[reply]
This is an tricky area. Many tropical cyclones do cause flooding, but some don't. Many never touch land, so where would the flooding be in those circumstances? Are they not tropical storms? As far as landfalling storms, I agree Andrew is an excellent example: a "dry" storm by many accounts, little flooding, bit ferocious Category Five winds. Some storms are weak as far as wind, but cause torrential rain. Tropical Storm Allison of 2001 is an excellent example of this. Another would be the first incarnation of '04's Hurricane Jeanne, which had winds barely of hurricane strength near Puerto Rico, but killed thousands with its torrents of rain and resulting flooding. So I would have to agree that flooding is not a requirement for a storm to be a t.c., it is a result of some: just like wind damage to structures and trees.

Title

Shouldn't the first letters of the two words of the title be capitalized? "Cyclone" isn't capitalized.--Ahmediq152 (talk) 12:45, 1 June 2009 (UTC)[reply]

Not necessarily, no; "tropical cyclone" by itself is not a proper noun. If it were, say, "Tropical Cyclone Bob", then it would be capitalized. –Juliancolton | Talk 13:51, 1 June 2009 (UTC)[reply]

this was interesting —Preceding unsigned comment added by 86.145.167.8 (talk) 17:30, 7 June 2009 (UTC)[reply]

Hurricanes and doldrums

In article doldrums, it says, "Hurricanes originate in this region." Also in "Weather Elements" By Thomas A. Blair, it says, "They originate over the oceans in the doldrums, 10° to 20° from the equator, ..." Is it true? If not, please clarify. Giftlite (talk) 17:06, 8 June 2009 (UTC)[reply]

should not be this page be named Hurricabe? —Preceding unsigned comment added by NoduloMan (talk • contribs) 21:16, 11 June 2009 (UTC)[reply]

No, because the term "hurricane" is only used in certain basins. –Juliancolton | Talk 21:19, 11 June 2009 (UTC)[reply]

Firefly Effect

I was wondering if the firefly effect (tiny electrostatic discharges generated when the winds of a tropical cyclone produces friction with sand particles) would be placed somewhere in this article? If not here, where should I place it? Wonderworld1995268 (talk) 18:32, 20 June 2009 (UTC)[reply]

Global warming and latest work by Emanuel

The article reference work by Emanuel from 2005, but not his more recent work in 2008. I have corrected this, and added the following:

In more recent work published by Emanuel (in the March 2008 issue of the Bulletin of the American Meteorological Society), he states that new climate modeling data indicates “global warming should reduce the global frequency of hurricanes.”[1] The new work suggests that, even in a dramatically warming world, hurricane frequency and intensity may not substantially rise during the next two centuries.[2]

"Hidden" vandalism?

"&&yes..kise is thee f'n best.!" at the beginning of the Eye and Center section and "<size="20">It's Kise Bitch.!" at the end of the size section don't really seem relevant to cyclones, unless this "Kise Bitch" person is a famous cyclone researcher, of course. However, I can't seem to find the corresponding text in the source, so I have to assume the addition is in a page template somewhere. How does one go about correcting those?

Nothing so difficult; it was reverted between the time you saw it and looked at the source. :) here: [4] --Golbez (talk) 17:30, 7 December 2009 (UTC)[reply]
