  1. @Bring Back 1962-63 Thank you so much for your incredibly detailed and highly thorough post. That was incredible information and I think more than enough to set me in the proper direction. When I first found this forum, one of the places I went to was the Research portal and I've read several papers within there. What you and other have put together is pure gold. Thanks again!
  2. Get smaller timescale for the indices we already have. So say for like the AO...instead of just a monthly value also generating a weekly or bi-weekly value (probably more bi-weekly than weekly).
  3. Yeah you can download the daily data (though I didn't see daily AO data from here...it's on the CPC site, but having trouble accessing the data). Anyways downloading it is not the issue...it's performing the calculations...well at least doing so in an accurate manner.
  4. Greetings all, For pretty much this entire decade I've always wanted to explore constructing weekly or even bi-weekly values for such indices like the NAO, AO, PNA (virtually whatever here is access to daily values too). However, I am not entirely sure how to go about such a project. I've read the methodologies used in constructing the monthly values and despite finishing school and going through all that math I (embarrassingly) suck at math...like awful. I've always wanted to do this, however, b/c I think having just a monthly averaged value doesn't accurately tell the story...unless the oscillation was in a particularly phase with consistent strength for an extended period. But at the end of the day, I feel like it's those transition periods which hold significant weight on pattern evolution/storms and having an index broken down into smaller time scales might accurately capture these periods more. I understand at the end of the day height anomalies and the placement of anomalies far outweigh the value of an indexed value, however, with this said I do believe there is a great deal of importance with having a value. For one, I think it can assist in research purposes. You can skim through values and sort of generate some thoughts/ideas and then explore charts/graphics. I thought perhaps may you could just take 7-days worth of data, sum them up, and divide by 7...but obviously it wouldn't be that easy. I tried a test of taking monthly values for a month, summing them, and dividing by the number of days in the month but this did not yield the same value as the monthly reading. I guess what I'm looking for is for some input/guidance from those who are far more advanced and knowledgeable with math then i am. (I've even considered going back and re-taking math classes from Algebra to Differential equations and approaching them differently...although I used to be really good with algebra). Thanks for any input/assistance! I also really love this place and have been doing a ton of reading the past few months on here...excellent source of knowledge and information here.
