QBO/MQI

[weatherwiz]

Are there any links in which you can view past/present/forecast structures for the QBO and MQI?  I've done a ton of searching but haven't been able to come up with anything and I'm tired of just looking at the 50mb and 30mb QBO data from these links:

http://www.cpc.ncep.noaa.gov/data/indices/qbo.u30.index

http://www.cpc.ncep.noaa.gov/data/indices/qbo.u50.index

With all the research going on and reading so many papers its just so apparent that the structure and configuration of these indices (same goes for NAO, AO, etc) is so much more important than just looking at a raw number.

IMO, this is the best chart for viewing and understanding the progression of the QBO at all layers (with data back to 1953): http://www.geo.fu-berlin.de/met/ag/strat/produkte/qbo/qbo_wind_pdf.pdf

I also like using that chart for forecasting the QBO.  You can get a feel for how fast / how slow the QBO is expected to progress by looking at prior years with similar progressions.

Here's the numerical data associated with that chart: http://www.geo.fu-berlin.de/met/ag/strat/produkte/qbo/qbo.dat

The chart referenced above only updates once a month, usually within the first week of the month. 

 

Here are a couple of alternate charts that update on a daily basis (but the QBO moves slowly, ha):

Sam Lillo developed the MQI which shows the QBO in a phase space plot.  To my knowledge, he only posts updates for the MQI on Twitter (@splillo), but not on a regular basis.

Thanks for these links and information!  Lots of great stuff to go over.  It's great to see such research being down which explores these indices so much further.  One thing I've wanted to do for so many years (but I just don't have the mathematical mind or skills to do it) is break down the other indices as well rather than just looking at a hard raw number.  What I've been wanting to do is break down the NAO and create bi-weekly readings instead of just having a monthly value.  I'm just not sure how to do it.  I thought I could just take the daily values for a two week period and divide by 14 but to test that, I took the daily values for January of 1950 and divided that sum by 31 and got 0.46 but the monthly value was 0.56 so that method wouldn't work.  If I can figure it out what I would then do is go to the ESRL composite page and re-create 500mb height anomalies for all the periods and then study structure/placements for positive and negative phases and go from there.  I know several years Allan Hoffman did some great work with breaking down NAO phases into east/west based as well.
