Article title

Any objections to me moving this article to 2007 North Indian Ocean cyclone season, a la the South-West Indian Ocean season articles? It would reduce ambiguity, since "North Indian" could refer to a part of India and not the ocean. --Core desat 04:26, 1 May 2007 (UTC)[reply]

Sure. - SpLo T // 08:25, 1 May 2007 (UTC)[reply]

Moved. --Core desat 08:45, 1 May 2007 (UTC)[reply]

Inclusion criteria

Should we, per last season, limit inclusion of storms to just those of at least deep depression strength? Depressions should only qualify if they cause a lot of damage and casualties, since depressions are generally weak (T1.5 or less) and would not qualify as a "tropical cyclone" per se. – Chacor 11:00, 4 May 2007 (UTC)[reply]

That is a great idea, limiting it to at least deep depression strength. After all, don't plenty of systems get upgraded to depression status and never reach deep depression? Hurricanehink (talk) 13:26, 4 May 2007 (UTC)[reply]

IMD classifies depression as tropical cyclones in their statistics. These systems usually have 10 minute mean wind speed of 20-25kt, corresponding to 1 minute mean wind speed around 25-30kt. A deep depression (30kt, 10min. average) is already close to a tropical storm in Atlantic. If depression is not notable enough, should all tropical depressions with little damage in Atlantic be dropped as well?Momoko 13:42, 4 May 2007 (UTC)[reply]

A system with a 15 kt max wind (according to the IMD shipping bulletins) - in any term of measurement - is hardly notable. This system has gusts/squalls to 25-30kt. That's not a tropical cyclone. It's a bloody tropical disturbance. Your comparison to the Atlantic is flawed. Tropical depressions are tropical cyclones; a depression is hardly one. – Chacor 14:03, 4 May 2007 (UTC)[reply]

In meteorology, a depression is used as a general term for low pressure system and can refer to system below tropical cyclone intensity and even non-tropical system.

However, the use of this term in the operational plan is much stricter.

Depression = Tropical Depression = max wind 17-33kt (including deep depression)

A system with a 15 kt max wind is a well marked low only)

Dropping the term 'tropical' is for simplicity only. A similar case is that we often refer a tropical cyclone as a cyclone in Australia but in meteorology, a cyclone can refer to a low pressure system other than tropical cyclone.

If you say that it's a bloody tropical disturbance, why was NRL stating 25kt? Why did come agencies analyse it as T1.5? This system is already at the borderline of a TD.Momoko 16:09, 4 May 2007 (UTC)[reply]

MfD on discussion archives

Hi, just drawing attention to Wikipedia:Miscellany for deletion/Tropical cyclone discussion archives. Up for deletion are all the archives of discussion about tropical cyclones on the seasonal pages, as opposed to the archives of Wikipedia-related discussion. See the nomination for the rationale for deletion. The thoughts of contributors here be appreciated on the discussion.--Nilf anion (talk) 21:22, 12 May 2007 (UTC)[reply]

IMD mentions BOB 03 as YEMYIN

One line extract from IMD press release dated 6th August 2007 for mid-season review of Southwest Monsoon 2007 mentions "This low pressure area intensified subsequently into a cyclonic storm `Yemyin’ over the North Arabian Sea (25th – 26th June) and crossed Pakistan coast." [1] —Preceding unsigned comment added by Ugaap (talk • contribs)

Excellent find! Do we have any other confirmation, such as a naming list showing the name already used? Hurricanehink (talk) 12:01, 10 August 2007 (UTC)[reply]

I guess we'll know by the next named storm. If/when it's confirmed, Cyclone 03B (2007) should move to Cyclone Yemyin, which is currently a redirect. – Chacor 12:10, 10 August 2007 (UTC)[reply]

I archived the press release here. --Core desat 20:13, 10 August 2007 (UTC)[reply]

According to Padgets contact at the IMD Yemyin has not been used #Padget so iguess we will have to wait and see Jason Rees —The preceding signed but undated comment was added at 02:57, August 21, 2007 (UTC).

This updated IMD report also lists BOB 03 as Yemyin. Hurricanehink (talk) 03:02, 29 October 2007 (UTC)[reply]

As did the WMO press release right after the storm. There shouldn'tve been a question that the next name won't be 'Yemyin' Good kitty 05:13, 29 October 2007 (UTC)[reply]

Still, good idea to wait to see what IMD does with the deep depression, just to be 100% sure. --Core desat 21:59, 29 October 2007 (UTC)[reply]

If the next one is Sidr, someone should remember to move the page over. We should find out in a couple of days. Good kitty 22:09, 11 November 2007 (UTC)[reply]

It's Sidr. I moved the article and changed things around to reflect the name change. --Core desat 06:54, 12 November 2007 (UTC)[reply]

BOB 03

As per JTWC regenerated 03B.NONAME had best status of 60 knots & 978 mb. while RSMC New Delhi (BOB 03) had it as Deep Depression indicating maximum winds of 33 knots. Could there be such a vast difference between one minute wind speed and ten minute wind speed for a very long period?--Ugaap 05:21, 29 October 2007 (UTC)[reply]

This storm was later upgraded to Cyclonic Storm Yemyin in the Julne monthly cyclone report, but I think people here are waiting until the next name storm to see if the IMD will be using Yemyin or Sidr. If not I think the article will note it did make cyclonic storm strenghth but was unnamed. - グリフオーザー 05:36, 29 October 2007 (UTC)[reply]

RSMC Bulletin

RSMC New Delhi bulletin issued by IMD on 29 October 2007 at 600 UTC has been given for next 24 hours instead of for shorter duration even though there is an active deep depression in the Arabian Sea. Also none of the RSMC bulletin has ARB number. What is the difference between the Bulletins of Cyclone Warning For Indian Coast and that of RMSC? IMD bulletins 7 & 8 are from the link to Cyclone Warning For Indian Coast and not from RSMC Bulletin.--Ugaap 15:08, 29 October 2007 (UTC)[reply]

RSMC Bulletin has since been issued at 1500 UTC 29 Ocotber 2007 for conditons as of 1200 UTC--Ugaap 17:32, 29 October 2007 (UTC)[reply]

The old IMD advisories used to be posted here, but got suddenly replaced by a TWO yesterday. Now, the advisories are found here. We assume that the Arabian Sea Deep Depression is ARB 02 because Cyclone Akash, the last cyclone in the Arabian Sea, was ARB 01. -- RattleMan 17:52, 29 October 2007 (UTC)[reply]

I think they did that because BOB 08-2007 was more important since it was affecting land at the moment.. for the Arabian storm ID number it should be ARB 02-2007 even though the bulletin doesn't say it.

The Tropical Cyclone Outlooks are probably used since the storm is hardly moving or affecting land. So tropical cyclone warnings/bulletins aren't necessary yet. -- "VOFFA" 18:30 UTC 29 October, 2007.

Im a bit confused What do we need to Webcite for this page and how often do the products come out? Jason Rees 18:58, 29 October 2007 (UTC)[reply]

The primary thing you want to archive are the advisories, but I'd archive the TWO as well. I haven't really figured out a schedule for issuance of them yet. -- RattleMan 21:02, 29 October 2007 (UTC)[reply]

Please check the advisories, it says" No Cyclone". The TWO is the Offical Bulletin. The first link is not the official RSMC Bulletin since it is a link for Cyclone Warning for Indian Coast.--Ugaap 06:59, 30 October 2007 (UTC)[reply]

Ok Guys Thanks - Please be warned as off 9am UTC this morning The JTWC Is issuing 6 hourly Advisorys so i will bring us up to date in a few mosJason Rees 22:50, 30 October 2007 (UTC)[reply]

Delayed RSMC Bulletin

Bulletin pertaining to BOB09 of 0900z (1430 IST) was available on IMD website too late--Ugaap 15:32, 11 November 2007 (UTC)[reply]

That seems to be usual for New Delhi RSMC since the second bulletin for 12pm is out now. -- グリフオーザー 19:22, 11 November 2007 (UTC)[reply]

Yeah i Know its now past midnight UTC and they have only just put up the advisory for 9 pm UTC Jason Rees 00:27, 13 November 2007 (UTC)[reply]

Sidr

As I stated in an above thread, the IMD has named BOB 09 Sidr. As such I've changed some things around to reflect the consequences of this - the Deep Depression BOB 03 section is now "Cyclonic Storm Yemyin", and the 03B article is now at Cyclone Yemyin. I may have missed some things, feel free to fix them if you see them. --Core desat 06:56, 12 November 2007 (UTC)[reply]

I suggest we use JTWC estimates for Sidr, and possibly other storms this year. They're not perfect, but none of the information from RSMC New Delhi resembles reality. I think it has proven itself as an unreliable source. Good kitty 22:04, 12 November 2007 (UTC)[reply]

we should use both at the minute but we need to Keep an eye on the IMDs Website for Fresh Advisorys

For Example i have just looked at the shipping Forecast which is located Here which says that The next bullitten will be at about 1 am UTC Jason Rees 22:39, 12 November 2007 (UTC)[reply]

I agree, the T-numbers are about 2 higher than are predicted in 24 hours by the IMD; the JTWC even is off by around 1. The IMD, however, was fairly reliable during Gonu, so it shouldn't be ruled out, and if it receives an article (which now seems imminent, although it could die or hit in an unpopulated), the IMD's ignorance, if it continues, should be noted. It all depends on how the IMD reacts to the storm in the next advisory. IPchanges ^{the box} 23:05, 12 November 2007 (UTC)[reply]

I agree the IMD is out to lunch at this moment. 992 mbar is unrealistic for any Category 3 storm even if the ambient pressure is extremely high (they are very seldom above 970). However, both sets should be used IMO as India may become more accurate later. CrazyC83 23:50, 12 November 2007 (UTC)[reply]

IMDS Advisorys are up and Archived the Pressure is now down to 985 (Rounded to nearest 5) Which seems a bit wrong still its now upgraded it to a "SEVERE CYCLONIC STORM" with wind speeds of 70 MPH. Also on another Note Can Someone start a Sandbox ASrticle for Sidr as i feel this storm is notable enough Jason Rees 00:26, 13 November 2007 (UTC)[reply]

BOB 09/2007/12 from RSMC (IMD) located SIDR at 12 N & 89.5 E at 0000 UTC 13th November 2007, however, the eye of SIDR was at 90 E at that time.

IMD has not been breaking the constraints on the Dvorak technique. As a result, IMD is not strengthening Sidr as fast as the JTWC has, and is essentially playing a long game of catch-up. Despite this problem, IMD is the official source for this basin, and its pressures must be used in the infobox at all times unless they become unavailable, even if it is an unreasonable number like 980 hPa. RSMC data always trumps JTWC data when it is available. --Core desat 04:29, 13 November 2007 (UTC)[reply]

130kts...is this the strongest storm in the Indian Ocean in November?? -Winter123 16:34, 14 November 2007 (UTC)[reply]

If there is an article on this storm (there is a very high chance, it seems), then we will have the lowest official pressure and the lowest real pressure, although the latter not in the infobox. We could also make a footnote in the infobox itself. And I believe it might be, but I'm pretty sure there's been at least one stronger one. But this one is much, much more evil. Can you believe that we get Sidr and Gonu in one season? Hyperactive season, maybe? When was the last time there were 3 category 1 or higher storms, 11 depressions, and 6 TSs? IPchanges ^{the box} 17:23, 14 November 2007 (UTC)[reply]

Knowing this is one of the last frontiers of cyclone history which is not well-studied, it is probably not a record season, but well above normal. An article is a virtual certainty (a sandbox could be started now) if the track holds. And yes I strongly agree the IMD numbers are totally wrong, but that is the official RSMC here. CrazyC83 18:12, 14 November 2007 (UTC)[reply]

Not well studied perhaps. The info is there alright people are just lazy! 1970 saw 15, 7, 3 (beating 2007 on first two)...--Nilf anion (talk) 01:27, 15 November 2007 (UTC)[reply]

Sidr sandbox

I just copied everything from the 2007 NIO article and I will expand it more this evening. I ask if anyone wants to add something, please do. User:CWY2190/06B 2007 ---CWY2190^T^C 21:41, 14 November 2007 (UTC)[reply]

IMD publishes a season report.

I just noticed this addition to their cyclone page[2].Potapych (talk) 14:08, 15 October 2008 (UTC)[reply]

This may need to be archived (if it isn't already).Potapych (talk) 14:13, 15 October 2008 (UTC)[reply]

One item of note is that IMD lists Yemyin and a Deep Depression as separate systems. JTWC considered it a continuation of the storm after it crossed the subcontinent. The numbering in the archives will need to be rechecked.Potapych (talk) 21:54, 15 October 2008 (UTC)[reply]

Ive Asked for Webcite to do it and it should com up here if it is successfull IMD Cyclone Report be warned though it will take its time as it did with the End of monsoon report 2008Jason Rees (talk) 18:27, 19 October 2008 (UTC)[reply]

Season Summary Map

Why isn't there a season summary map for this year? You know, a chart of the storm tracks this year; why isn't one of those in the main infobox? 76.235.205.44 (talk) 23:43, 21 November 2008 (UTC)[reply]

A seasonal summary map is still unavailable. I can do these kind of maps but I have no much time for this. -Ramisses (talk) 00:45, 22 November 2008 (UTC)[reply]

Its a fact Seaosnal Maps do take there time to do unlike the invidual storm maps Jason Rees (talk) 00:49, 22 November 2008 (UTC)[reply]

Oh. I was just asking because for every season from 1990 or so to 2006, there is a map, and I was wondering about this season having one. 76.235.205.44 (talk) 02:46, 22 November 2008 (UTC)[reply]

A seasonal summary map is now done. -Ramisses (talk) 16:40, 29 November 2008 (UTC)[reply]

As Always Ramisses it looks good though i would use the IMD besttrack for the Depressions/DD that the JTWC did not monitor Jason Rees (talk) 17:13, 29 November 2008 (UTC)[reply]

Why is there a 2008 season effect chart here?

I really don't know why the season effects chart in this year is the one of 2008. If there is one, it should be from 2007, not 2008. Anyone agree? 76.236.178.224 (talk) 20:10, 15 March 2009 (UTC)[reply]

I put it in with the intention of putting it into 2007 data just got distracted by other things.

Possible record

I don't know if this should be mentioned, but this season had more category 5 storms than the western pacific basin. Should this be noted in the main article somewhere? It is the only time it ever happened before. 98.206.70.2 (talk) 17:11, 27 March 2010 (UTC)[reply]

No - Its an unofficial record as neither the IMD or JMA use the SSHS.Jason Rees (talk) 17:17, 27 March 2010 (UTC)[reply]
