  1. Hi- yes there is a sign for SSW but there is no sign for negative AO (I mean a really negative ssw AO values). For example the EC Ensembles are expecting that the AO will go up again after a negative values for a short time !
  2. hi- so Kara Sea block makes the a AO go negaive ?!
  3. Hi guys..i want to ask a question what is the different between ecmwf eps mean and control ?
  4. The ECMWF monthly control in too good for my country -Israel- at new year's eve
  5. I mean at the end of the year and At the beginning of the new year.
  6. Hi - it seems that the sceuro high is fixed and the trough will go down to turkey and israel
  7. Hi..Maybe the question mark will go to middle east / Israel maybe !
  8. yes you are right. i mean the PV will be less stronger.. AO will peak strongly positive early next week before drifting back towards neutral. however in AER, they say : " if our expectations of more upward pulses of WAFz is correct, this should be sufficient to force a sudden stratospheric warming (SSW) sometime in January" i think SSW makes the PV very weak which mean AO negative ... am i right ?
  9. Hi- thank you so much and thanks for the helpful topics in your previous comment. So the waves affect the PV by split or displace it ? But how that affects europe ? By the way there is a sign for a weaker PV i think !
  10. Hi - i have searched all the pages and i can't find the answer of my question. how can i read the charts and what is the impact of the waves on strat and AO index ? i'm sorry for asking too mush question
  11. Thank you so mush Chionomaniac I have another question what does this charts mean ? And what does this chart use for ? And what do Wave 1 and 2 mean ?
  12. Hi guys i'm a new member i want to ask a question... i have a problem reading the zonal wind charts. I know that red means westerly wind and blue means easterly wind, so how can i use this chart to predict the strat temperature and AO index ? Thank you
