A little thought exercise. Look at the current SSW. Note its size and duration. See how widely felt the impacts are. Now expand that to the whole arctic basin warming the trop above and do that for 2 months ( at least ) How wide would those impacts be felt? And what specifically would those impacts be?

No idea what your trying to say....the arctic does not warm....repeat...warm the troposphere... There is no heat source up there. And trying to relate this to SSW is crazy, the stratosphere does not care wether we are here or not, not even 0.001% It does care how much UV it receives.... I do not understand the impacts of what you are referring to??

The warmer the SSW event, the faster megajoules of heat are leaving the planet. A cooling event does seem to be taking place. Anomalies are great to express temps compared to a baseline, in pictures. They are horrible as far as showing actual temperature deviation directions.

www.sciencedirect.com/science/article/pii/S0277379113004162?np=yStudies of the GRIP ice cores and high latitude North Atlantic sediment cores show that the Bølling–Allerød period (c. 12,700–14,700 years BP) was a climatically unstable period in the northern high latitudes and we speculate that this instability may be linked to dual stability modes of the Arctic sea ice cover characterized by e.g. transitions between periods with and without perennial sea ice cover.

papers.ssrn.com/sol3/papers.cfm?abstract_id=2869646Detrended correlation analysis of mean monthly sea ice extent with air temperature at an annual time scale in both Polar Oceans shows the expected negative correlation in 14 out of 36 cases studied. The other 22 cases, including the high profile case of September sea ice extent in the Arctic, show no evidence that temperature alone explains sea ice extent. We conclude that other factors such as wind, clouds, solar irradiance, and ocean circulation may be relevant in the study of differences in mean monthly sea ice extent for the same calendar month from year to year.

No shyte siggy! You don't see a retreat like this in Feb in Bering from sunshine! Warm,salty waters and high ocean swells as weather pounds the region.... On average we have less than 3% of freezing season to go. How much hostile water will we see in the basin come Aug? Better hope for another cool,cloudy 5 months eh?

The big Arctic energy exhaust is going flat out. Yes GW there will be consequences but what?
The negative relationship of the Antarctic sea ice extent indicates that our intuitive metric of more ice colder, less ice warmer is faulty.
The satellite era has given us more and more wiggles to watch but I suspect that in 10 years the watched wiggles now will be replaced by some better wiggles and the vexing will center on different issues and I would argue a different "religion" maybe very certainly a modified one.

Looks like DMI 80N might throw us a surprise on tues/weds?
If the forecast holds then we see positive temps flow in through Fram , over the pole and Beaufort and into Chukchi!
What was that about polar energy?

IF there is energy at the polar area, it is leaving quickly......very quickly.

The warm air that is getting Graywolf all excited, is coming from the south up to the pole where it radiates rapidly (in Dutch - Infrarood uitstraling) out to space. All that carefully hoarded heat escapes. The polar air meanwhile that has been displaced by the wave of stratospheric air has to go somewhere and UK happens to be in the path of some of that polar air for the next week or so.
