Interactive Area for Members - Feedback and Comments

 

This area is for you "the forum members" to get more involved where you will be able to share your views, comments, feedback and ideas about any aspect of this Research Portal by using the standard "reply to this topic" option below this page.  You may have found a paper that you feel is suitable for the portal and would like us to upload the link into the portal. Full instructions for this are shown lower down on this page. 

 

Your Feedback, Comments and Suggestions

There may be all sorts of reasons why you might wish to contribute to this area. These are just a few of them:

 

1.  To help other visitors and researchers - for example:  recommending further reading and suggesting other suitable papers covering specific "teleconnection" related subjects (see full instructions below).  

 

2.  You might wish to make comments or suggestions to the research portal moderators - for example;  you might be aware that a particular author or paper has been discredited or the paper or theory has been superseded or supplemented by a later paper. We do not wish to or cannot be "judge and jury" and we will rely on input and feedback from you, the readers.  So please bring this to our attention.

 

3.  You may wish to provide a link to a special site where you feel certain information/data/charts are very useful and this is not easy to find in a run of the mill search (see full instructions below). 

 

4. You may have noticed an error - for example: we may have missed out inserting a tag, used on a paper, into the search list.  Please let us know.

 

5. You may have ideas for how we might develop the portal further or feedback on the current functions. 

 

6. You may wish to discuss something that you have read in one of the papers.

 

Holding Area for Members to Park Papers Awaiting Upload - Requirements and Instructions (+ example)

If possible please provide the following details and copy this into the standard "reply to this topic" shown under this page:

-  the full title

-  the author(s)

-  the publication date or year (if known)

-  copy the full abstract or summary if there is one (if not then a brief description about the theme and contents of the paper would be helpful)

-  state the tags required (or alternatively, the main teleconnection related topics featured in the paper). Direct link to List of Tags  (in User Guide)

-  copy the link to the full paper (please do not copy the whole paper). 

-  add a note if you have anything to explain to us.

 

Then one of us will upload it.

 

Here's an example of one that was uploaded earlier to show the information required (with instructions in red):

 

Mountain Torques and Northern Hemisphere Low-Frequency Variability. Part I: Hemispheric Aspects    (full title)  

 

Authors:  Francois Lott, Andrew W. Robertson and Michael Ghil  (author/s name – if there are many authors you can use the first name and then “et al”)

 

First Published:  2001  (the date the paper was “first published” if known which may be much earlier than when it first appeared online – or both dates) 
 
Abstract:    (the full abstract or summary if there is one and the link to the abstract)

The NCEP–NCAR reanalysis dataset for 1958–97 is used to analyze intraseasonal variations in mountain torques and the large-scale atmospheric circulation patterns associated with them. Spectral analysis of the atmospheric angular momentum (AAM) budget shows that the dominant variations of mountain torque have periodicities near 30 days and shorter, while the dominant AAM variations occur in the 40–60-day band. This difference is due to the 40–60-day AAM variations being primarily related to equatorial processes, while mountain torque variations are associated mostly with extratropical processes.

The Northern Hemisphere (NH) mountain torque has enhanced power and significant spectral peaks in the 20–30-day band. The signal in this band accounts for 33% of the NH mountain torque variance, once the seasonal cycle has been removed. Lag composites of the NH 700-hPa geopotential heights based on the 20–30-day mountain torque signal show the latter to be associated with coherent large-scale patterns that resemble low-frequency oscillations identified in this band by previous authors. The composite patterns that are in phase quadrature with the 20–30-day NH mountain torque have a pronounced zonally symmetric component. These patterns are associated with substantial AAM variations, arguably driven by the NH mountain torque in this band.

Principal component (PC) analysis of the NH 700-hPa heights shows that, in the 20–30-day band, the mountain torque is also in phase quadrature with the two leading PCs; the first corresponds to changes in the midlatitude jet intensity near the subtropics, while the second corresponds to the Arctic Oscillation. The relationships with AAM of the latter essentially occurs through the mass term. Mountain torques are, furthermore, nearly in phase with dominant patterns of low-frequency variability that exhibit substantial pressure gradients across the Rockies and the Tibetan Plateau.

Please note that the following tags were allocated to this paper:  mt, aam, mjo   (your suggestion for suitable tags – optional as we can add these)

Wow, just wow. This is a phenomenal resource. Looking forward to having the time to dig into some of this stuff over the summer. Hats off to @Bring Back 1962-63 for building this up!!

Thank you for your kind comments Jack.  It has been very hard work but very enjoyable doing it and reading through all these papers really helps focus the mind and has really assisted my own learning. We hope that when it gets busier on here later in the year that many more members will use the portal. We've tried to build up a real mixtrure of teleconnection related topics to provide for a wider range of interests and there are "early learning" guides as well as much more advanced material.   We're hoping that this interactive area will be used to discuss papers and exchange views and ideas.  David :)

Have just found the portal and I am looking around.

My first day with a bit of time to search around and so far looks excellent.

Thank you Dave (MIA) - it's great to have some appreciative comments and we do want to encourage the use of this Interactive Area...so please provide any relevant feedback or suggestions for further entries into the portal at any time.  I've been distracted from my latest glacial ice post (75% done now and posted in early draft form onto the Arctic thread to avoid losing some of it again) as I replied to some of the inaccuracies on our UK forum Antarctica thread. I may copy that (edited slightly) onto the "33" Climate Change thread later today to provoke some friendly and important debate with our US cousins. 

 

I see that you're checking Arctic ice growth daily.  I will give that until Nov 6th/7th to review it.  I like your animated chart (which does need to be accessed from your link to work).  I do note the increase in the Kara Sea area but also the retreat or melt in the Bering Sea for the very reasons that I suggested. Now that the ice sheet has bridged most of the gap to the Siberian side this does assist further build up (open water currents are dammed) but lower temps are needed to sustain this and to allow further rapid growth. The pause that I predict may still happen soon.  Reacting every day to ice changes is a bit like reacting to every model run and for us Arctic lovers makes it a bit of a roller coaster.  I'll be happy for you to provide daily or at least regular updates and I'll comment from time to time in between fuller updates.  I've got a vast amount on right now both businesswise and weatherwise - just wish I had even more time.  David :)
