New teleconnections page - feedback requested


Recommended Posts

I started developing an all-in-one teleconnections page, but before I delve into this I would like some feedback from the weather community. The goal of the page is to make monthly US surface temperature anomaly maps of different teleconnections using the 1981-2010 normals plotted in Fahrenheit. The only maps I have now are the monthly negative NAO maps, but I plan on doing maps for the different phases of AO, NAO, PNA, EPO, WPO, PDO, AMO and QBO at 30mb and 50mb.

Here's the main site: http://madusweather....eleconnections/

And here's the link to the negative NAO maps: http://madusweather....on/nao_neg.html

The full list of sources, methodology behind the maps and links to anomaly maps on other sites are included.

Is this a site that you would use? Do you have any suggestions for the content and/or site design?

Why am I doing this? I want to have monthly correlations for each teleconnection using a single scale and single standard across the board. There's already maps for these temperature anomalies in different parts of the web, but I think having a consistent, one-stop site for all the essential teleconnections using the new 30-year normals would be extremely useful.

Thanks in advance for any comments and suggestions you may have!

Would be nice to have it all in one easy to access place for sure. One thing that'd be awesome is if you could create anomaly maps combining multiple teleconnections (e.g. a map of temperature anomalies with + in one teleconnection and a minus in another)

EDIT: Then again, I'm not sure how your making these maps. If you're planning on actually going through and creating a individual map manually for each teleconnection, obviously it'd be a bit of an undertaking to create a map for every single possible combination :P)

Great maps though and easy to browse through! Would be interested to see the MJO phases and I know it's a reach but...GWO too!!!

That would be a good deal more difficult for me to do, and I'd have to use a different map to plot time periods... I'll see if that's feasible, though.

I'm going to be making the maps by hand (it's much quicker to do it on the ESRL site given the amount of programming and data mining it would take to make my own custom maps). Maps with multiple teleconnections was an initial thought/plan of mine, and I might add those once I get the main set of maps completed.

Either way great work! Looking forward to see the EPO composites since I don't think any of those have been published that I can find on the internet.

If your doing the GWO monthly, you need to average the daily GWO's in the month. I have made a fortran program to do this, it was alot of work. Essentially you need to average the aam/tendency (x/y data) data per each month, convert it to polar form (angle/magnitude), then realize how the octants are tilted & angled. From there you can make 8 octant bounds, the tricky part is figuring what the value of magnitude should be for the Cicle of death, it's different when you average 30 days, instead of just 1 day.

I was looking through the data for MJO/GWO... seems like a real pain to try to get monthly anomalies out of it. I'll defer to existing sites/maps for those :P

I am sure you can just just use the dates off Allen's site for the MJO :). What sites offer composites of the GWO? The only one I am aware of is the ESRL site and that is only the "day of" composites. I don't think you can view it for didn't times of the year.

I know you put a lot of work into it and your program sounds amazing...would you be willing to share it with those of us who are interested in trying it out?

Added the negative, neutral and positive EPO maps using the old calculations (so we could have something for December!):

http://madusweather.com/teleconnections/

And yes, there are some correlations to be had with the neutral phase. I double-checked them with the new EPO calculations for Jan and Feb and the signals aren't nearly as strong... I'll get the maps for the new EPO out the next time I get updating.
