AfewUniversesBelowNormal Posted March 4, 2019 Share Posted March 4, 2019 http://research.jisao.washington.edu/pdo/ I don't think we were ever truly in +PDO 2013-2018, to be honest. (anomalous blip.) It's long term -PDO right now. Link to comment Share on other sites More sharing options...
raindancewx Posted March 5, 2019 Share Posted March 5, 2019 You had a big spike in the -PDO era in the 1950s too, with the double El Nino of 1957-58 to 1958-59. I'd call it 2014-2017 positive, 2018 neutral, with 2013 still negative mostly. In the 1950s, it was kind of mid-1957 to mid-1960 that was mostly positive. 1957 -1.82 -0.68 0.03 -0.58 0.57 1.76 0.72 0.51 1.59 1.50 -0.32 -0.55 1958 0.25 0.62 0.25 1.06 1.28 1.33 0.89 1.06 0.29 0.01 -0.18 0.86 1959 0.69 -0.43 -0.95 -0.02 0.23 0.44 -0.50 -0.62 -0.85 0.52 1.11 0.06 1960 0.30 0.52 -0.21 0.09 0.91 0.64 -0.27 -0.38 -0.94 0.09 -0.23 0.17 Link to comment Share on other sites More sharing options...
