AfewUniversesBelowNormal Posted April 19, 2018 Share Posted April 19, 2018 The strength of this Greenland block was amazing in October. The ease for these W-E wavelengths to happen so far north so early in the year. It would be hard to imagine a noncold Winter surrounding this. 18-19/19-20. Looking back over CDC analysis maps since 1948, there is a definite 2-3 year trend. Link to comment Share on other sites More sharing options...

AfewUniversesBelowNormal Posted April 19, 2018 Author Share Posted April 19, 2018 2017-2018 was the first Winter on record (since 1948) that had so many 50N-90N blocks. I think there were 8-9 compared to 0 PV that strong anomaly-wise. Link to comment Share on other sites More sharing options...
