Hi all, I just wanted to say what an awesome site this is, as a forecaster myself running a private weather forecasting service, this was an amazing read, and has so much resource tools that are hard to find. Having the legendary JB on board is also fantastic, I have been following him for well over a decade. Thanks again for a fantastic forum.

Great to have you on board!

Glad to see another Australian on the site! You just forecast for the Adelaide region?

Hi Geoff,  Malcolm just alerted me to this and I sent him the following PM which I'm sure he will not mind me reproducing right here:

 

Hi Anthony, I often followed your excellent posts on several forums.  Your tweet requesting AAM etc data sources has just been brought to my attention and the following should help.

 

Since the service provided through WDT was withdrawn there was a gap in this vitally important data. I've been in touch with Ed Berry, who along with Dr Klaus Weickmann (who retired 2 years ago)  developed the GSDM (I posted on that on both the 33 and NetWx forums with Ed's excellent presentation earlier this year) and he told me that a friend of his still processes this data.  He has kindly provided a link to that site plus the access user name and password:

http://gsdmsolutions.com/~gsdm/clim/aam.rean.shtml

un = gsdm01

pw = gu3st#1

 

That will take you to this page where you'll find a lot more than just the ex WDT data:

 

Monitoring of Global Atmospheric Angular Momentum (AAM) Budget

NCEP-NCAR Reanalysis

 

While I'm on this subject, it may be useful to show the other links that we have:

 

1. Nicholas Shiraldi - Albany for the GEFS AAM and GWO plots  - Note that this has not updated since June 28th 2018 due to ongoing GFS technical problems which we are assured will be resolved in due course (but no date given yet).

http://www.atmos.albany.edu/student/nschiral/gwo.html

 

2. SCW (South California Weather Notes) - this site provides a vast number of links although some are no longer available (such as the NOAA map room for AAM etc).  It is well worth exploring what's on offer, including some useful archive data.  For the GWO previous/current (but not forecast) plots go to the "Quick Link" near the top of the page and click on GWO/FNL.  The chart sometimes appears as a silhouette but will copy okay. This is the "final analysis" using GFS data.  Klaus Weickmann developed this as a way of checking the forecast output against what actually transpired. It is very useful as it doesn't appear to have the same strong -ve biases that GEFS are known to have. it is updated towards the end of each day.

http://www.sierraphotography.com/wxnotes/weatherlinks.htm

 

3. Dr Victor Gensini -  a research scientist in this field has been developing his own site during the last year.  It is still evolving but already has some extremely useful data.  Victor has been attempting to correct the GEFS -ve bias but his source data is suffering from the same technical faults - so not reliable right now. He also includes CFS output which has a rather +ve bias and allowances need to be made for that. He plans to process and add torque data in due course. Victor Gensini and Ed Berry are in regular contact with each other and may do some joint work providing that they can get the financial backing (always a problem in this area).

I have been away from NetWx (UK forum) for much of the summer and Malcolm @Blessed Weather and I (+ several others) have been very busy developing a Research Portal on the 33 forum. We plan to be active on NetWx and 33 and may cross post on to both sites, especially for Teleconnection posts. We will be reviewing some excellent papers and presentations on both sites. If you have not yet had a chance to have a look, here's a link to the portal:

https://www.33andrain.com/forum/51-teleconnections-research-portal/

 

I suggest that you look at the comprehensive index. From there you can click on a title, that will take you to the abstract. After reading that, you can decide if you want to read the full paper and a direct link is provided. I had wanted to develop the portal on NetWx but it never got off the ground.  We got tremendous encouragement and support on 33 from Geoff and Pat. 

 

Perhaps, if you have time, you might like to get involved in our teleconnections debates on 33 in particular.  We've been having an ENSO discussion (more stalling seems likely) and have discussed the 2018 SSW and AAM etc.  David :)  

 

 

 

 

 

Is there any way this post can be pinned somewhere near the top of the thread or somewhere on the forum because I constantly have to look for it every time I go to the site?!

 

Thanks!

CREATING A TELECONNECTIONS THREAD INDEX PAGE

It's not a bad idea for the thread in general. Someone should create a post which links to the greatest hits and then we can pin that post. @Bring Back 1962-63 or @Blessed Weather;) 

 

This is something that I suggested a few weeks ago in several PM exchanges. I know exactly what to do and it will be based on a smaller version of the index page used in the Research Portal. It's just a question of time. I will start it off later this week, working from page 1 of the thread with the main and more important posts.  Probably about 10 to 15 topic headings and direct links to each of the posts listed + the posters name. Some longer posts may appear under several headings (eg: ENSO and AAM).  I'll do the first part around Thursday. It will evolve over several weeks.  It can be edited and added to just like the Research Portal.  David :) 

 

EDIT: 

Hi Zac @Snowy Hibbo we're talking cross purposes here - these are two separate matters.  What I'll be preparing is an index page with links to the more significant individual posts on this thread listed under topic headings for each Teleconnection (this will take a lot of work and time to prepare and will be done in a similar way to the Research Portal index).  Once I've got it started, you, Malcolm @Blessed Weather and I can keep it updated as new posts appear on this thread. I will be doing the same for the Arctic thread.  Continuous "specialist" threads contain a wealth of information which is difficult to find and a comprehensive index should help all members. I mentioned this idea a few times in several PM threads 

 

The matter that you are referring to is links to sites and you have already been adding these to your introductory post to this thread since the thread started and is where the reference should be.  I also noticed that you recently added the "AAM/torques" links with the access and password info that I provided in a post on July 1st after Ed Berry kindly provided me with the new link to his friend's/colleague's site.  I had also repeated it a few weeks ago (on October 1st) in a reply to an Anthony @antmasiello_HM PM query and the @griteater tweet that Geoff copied to this thread. Yesterday,  Eric @Webberweather and Geoff @33andrain may not have realised that you you had/have been showing these links in your opening post. Then Geoff, in his usual helpful and efficient way,  pinned my link post to the top of each page.  I feel that this should be replaced with your introductory post pinned to the top of each page with a "useful Teleconnection links" heading (or words to that effect). Obviously you will be adding more links to your introductory post just as I do for the Arctic thread - it's continuously evolving.  David :)

There's already a big list of links in the first post. Including the Berry stuff as of yesterday. I can extend it if you like, or add it to David's proposal?

@Webberweather how do I extrapolate this in layman terms? Is this more like modoki or basin wide signature? Do I guess right that this would feedback in to higher state of AAM tendency and MJO in cold phases 7-8-1 and more meridional atmosphere(-NAO) thanks

Jules,

I believe  that he is referring to the strengthening of the Modoki nino that will run the mjo into the 7 through 2 phases, BUT he is member here so maybe PM him and ask on here.
