Talk:2009 Atlantic hurricane season/Archive 1

ACE
We shouldnt be using it in the predictions as niether the UK Metoffice, NHC, or other RSMCs use it in their seasonal predictors. Thus i propose removing it where ever it is used. Jason Rees (talk) 04:35, 12 April 2009 (UTC)
 * Removed from predictions. Ir ' di ' ce  nt  23 14:22, 12 April 2009 (UTC)
 * Perhaps we should remove it from the table, but if they're reporting it, the text description should include it.--Prosfilaes (talk) 01:34, 13 April 2009 (UTC)
 * IMHO we should remove them until after the season, because of they're changing every 6 hours and, until the TCRs are out, are some kind of OR. --Matthiasb (talk) 16:37, 17 May 2009 (UTC)
 * What's them? Certainly the ACEs in the predictions aren't changing nor OR. As for the ACE in general, there's no problem keeping a live update of them, and they're simple computations based on reliable sources.--Prosfilaes (talk) 02:03, 18 May 2009 (UTC)
 * Actually they're changing (because later BT data differs from operative data, and calculating them from the NHC predictions actually is OR. --Matthiasb (talk) 14:09, 19 May 2009 (UTC)
 * No; December 10th, 2008 is in the past, which predictions made that day will never, ever change. As for the current ACEs updated live, all we can do is work with the best we have, and if this uncontroversial calculation on well-established sources is OR, then I offerWP:IAR.--Prosfilaes (talk) 16:30, 19 May 2009 (UTC)
 * Well but we discuss 2009 which is in the future. ;-) --Matthiasb (talk) 12:20, 27 May 2009 (UTC)
 * Is that argument for the sake of argument?--Prosfilaes (talk) 14:07, 27 May 2009 (UTC)
 * They are not OR because the NHC (a.k.a. RSMC Miami) is the official hurricane warning center for the Atlantic ocean, and therefore, their products are official. They revise them post season, but during the season, they are the most correct and official data for hurricane strength.-- An ' ha ' mi  rak 20:33, 27 May 2009 (UTC)
 * See OR.--151.204.240.46 (talk) 21:26, 28 May 2009 (UTC)
 * Calculating ACE is not really a routine calculation. There are multiple steps involved in figuring it out, and for what purpose? ACE is not supposed to be used for individual storms.--♬♩ Hurricanehink ( talk ) 21:33, 28 May 2009 (UTC)

Invest
Should someone put the advisories for a invest up? HurricaneSpinTalkMy contributions 19:10, 17 May 2009 (UTC)
 * This is just like a normal invest. We don't put anything in the article until it's a (sub)tropical cyclone. --♬♩ Hurricanehink( talk ) 19:14, 17 May 2009 (UTC)
 * Like .HurricaneSpin TalkMy contributions 19:22, 17 May 2009 (UTC)


 * It hasnt been put up on NRL [yet] when it is it will be placed up in the logs Jason Rees (talk) 19:24, 17 May 2009 (UTC)

Do you put low, medium, high like JTWC do? There is a lot missing compared to JTWC stuff.HurricaneSpinTalkMy contributions 01:23, 18 May 2009 (UTC)


 * The JTWC doesn't release advisories for the Atlantic.
 * The only things logged from this basin:
 * NHC
 * Tropical Weather Outlook
 * Tropical Weather Discussion
 * Special Tropical Weather Outlooks
 * All advisories released
 * The NAMOC's TCFAs
 * NRL invest appearance/disappearance dates
 * HPC and CPC's advisories, if applicable
 * -- RattleMan 06:56, 18 May 2009 (UTC)

Now officially a invest, 90L. GTWO give low medium and high. HurricaneSpinTalkMy contributions 20:37, 18 May 2009 (UTC)

Why didn't it became a tropical cyclone? 1003 milibar and 30kt is usually a depression, and it is clear that is is enough organized that it is better organized than a normal depression. Is their other limits? HurricaneSpinTalkMy contributions 20:19, 23 May 2009 (UTC)
 * Convection didn't fully wrap around the circulation and it hadn't maintained that structure for long enough. Cyclonebiskit 20:23, 23 May 2009 (UTC)


 * Convection did, at least better defined than a lot of tropical storms, besides, Tropical Storm Arlene (2005) barely have any convection, so it didn't maintain its good structure long enough for NHC to issue advisories? HurricaneSpin Talk My contributions 20:39, 23 May 2009 (UTC)
 * Again with the same old thing. The NHC knows a lot more about classifying storms than we do. I'm sure they had their reasons.
 * On a related note, why is it that amateurs (like me) always think they know better than the people who got PhDs and have been doing this for years? There has to be a name for that phenomenon. - Running On Brains (talk page) 21:19, 23 May 2009 (UTC)
 * There is a chance that this system will be upgraded to a tropical storm after the fact. A request has already been made, from a third party, for rainfall graphics, which will be made once the low dissipates.  Thegreatdr (talk) 18:54, 24 May 2009 (UTC)
 * If 90L is upgraded after the season ends, it will likely be an unnamed Tropical Storm, as the best track had it's peak strength as 35 knots and 1003 millibars.96.30.150.26 (talk) 01:37, 25 May 2009 (UTC)

It might indeed. If it gets declared an unnamed (S)TS, then it would be added to the storms list (and an article created?) at the time of its declaration. Since the peak strength is up to 35 kt, they might do it for HURDAT. If it had remained only depression-strength, they would not have done anything since tropical depressions do not go into HURDAT. CrazyC83(talk) 17:54, 28 May 2009 (UTC)

And we just had a second candidate for a post-season upgrade. Since 90L had significant land impacts, it would clearly warrant an article if reanalyzed as an unnamed TS. 92L, not so.CrazyC83 (talk) 03:05, 4 June 2009 (UTC)
