Hi Recretos. I posted once here and i have been reading your posts. this group is exceptional IMO. basically u said the whole truth. I am learning the effects that the PV is having in my region.. Canada and USA. my question to you is the following: since we are more then likely to have a year where the PV does not split whatsoever , what other years prior to this one it has ever occurred? did it ever occur at all ? a non split of the PV? If so I would assume that since the vortex will remain localized over NA, would that infer a high possibility of a much colder spring then usual? i would appreciate if someone could provide some feedback. thanks

hi gents. I have been lurking in your forum for awhile. I am starting to learn tids and bits through the vast array of posts in the website . I see several dedicated and enthusiastic members posting here. I have a few questions . i have seen quite a bit of enthusiasm from yesterday's runs in regards to an SSW . I noticed the following from Berlin (yesterday) ... see below If an SSW was supposed to be pronouncing itself wouldn't we see an increase in temperature between 1-5 mb from 70N/90N? forgive me for the lack of terminology capacity that u guys have. I also do not see berlin ( again) showing anything that would actually give us more certainty from the following ... -QBO is more pronounced but we see no drop in temps at 70N/90N at 10 hpa. i would appreciate if someone would pitch in. As recretos says ... he did not know much not too long ago. I hope i can at least learn 10 % of what you guys know. cheers
