  1. I'm a bit rusy with my maths and Fourier but it seems there is decelerating wave.
  2. Okay, ECM was upgraded recently (after last years winter at least) but oper still runs at higher resolution (9 km grid spacing vs 18 for ens)
  3. ECM operational is run at much higher resolution, the GFS operational and perturbations all run at the same lower resultion
  4. At 10 days models are about 40% right, so it safe to say that what the day 10 chart gives you won't be the weather you'll be getting . After 10 days the predictions get even worse off course, much worse....
  5. winter tend to be either cold and dry or warm and wet but we do sometimes get some nice snowy ones (78-9, 12-3 was good too)
  6. All strong and very strong ENSO events have been bad winters in the Netherlands, the best winters saw no events or weak events
  7. Not a fan myself but I am curious to know and following someone on twitter is cheap and easy
  8. I was looking at the Dutch data, perhaps that's why but if it's cold here you can bet it's very cold all through western Europe
  9. Winter 2000-2001 was very unremarkable in W-Europe though. The impressive 78-79 and 62-63 winters saw end januari ssw's
  10. For everyone not already following Judah Cohen, follow him on twitter so he will release his magical snow advance index
  11. The nice blocking weather we are having with clear skies which causes the fog later bring snow?
  12. thanks for the welcome, exciting times, we are heading into the uncharted
  13. I haven't watched followed the model and winter forecasts for very long, in fact only since last year but from what I understand is that 2016 is a year in which unprecedented, unpredicted things happened like the sudden reversal of the QBO, the very early SSW and PV split, immensely hot arctic and incredibly cold snowy Siberia and all the excited tweets from Matt Hugo and Judah Cohen, I think we are in for quite a surprise this winter and the models have no clue...
