I don’t understand how you put out a winter forecast with zero explanation or discussion, nothing, nada. Just “I think it’s going to be very cold and snowy”.

stadiumwave Posted October 17, 2022 Share Posted October 17, 2022 JMA updated...models kind of looking stellar for NOV & then DJF kind of looks like a blend of 2020-21 & 2021-22. NOV DEC JAN DJF Kind of a blend of 2020-21, 2021-22 with mean trough a little further west. Now the JMA mean pattern is similar to the upcoming pattern & it could be the monthly & seasonal model output is heavily influenced by that. It happens. Or it could be the upcoming pattern is very much indicative of the winter mean pattern. Personally I still think it's too early to know. I lean towards some of NOV & maybe early DEC could be colder pattern & then who knows after that. One of the key players is what will the PDO do. Right now it's positive but really means nothing as of yet, it can change in a hurry as Fall N. Pac SST's can fluctuate greatly. I think if we get the earlier peak of La Nina the transition towards +ENSO may be pretty quick & hold some +PDO. We'll see. 1 Link to comment Share on other sites More sharing options...

Sample size ruined it. It's simply not a dominant signal. All else being equal and null then sure it probably holds some merit. JMO CC gets blamed for a lot of stuff, and then it gets memory-holed when that "blame" doesn't turn out correct. CC was causing more +NAO/AO in the late 1990s/early 2000s, and then it all of the sudden wasn't....it "changed" and we saw all these papers about low sea ice and -AO/NAO.....then that "changed" too in recent years when had trouble getting big -AO/NAOs. I've actually asked people about this who work in the field and the answer I get is typically something like "there's a lot of pressure to come up with CC attribution studies"....which is understandable, but I wonder if it starts degrading the quality of the research when we try and rush to attribute 5 and 10 year trends (such as with the AO/NAO) to CC. I think the law of large numbers isn't appreciated enough on some of this stuff....hard to get really confident answers when you are using sample sizes in the low 10s. The only truly robust CC signal we have on winters is warmer temperatures overall (and especially low temperatures), though the temporal/spacial variation is still very large (see central Canada/N plains/N Rockies with a 30 year cooling trend in winter). 11 Link to comment Share on other sites More sharing options...

There's zero doubt! And sadly, there's plenty of grant money available "depending" on the nature of your study. This will bite us at some point. The truth is, taking into consideration what you posted we really need to understand while we strive to understand we just simply do not know as much as we would like to think we do. Makes you wonder what else we'll be wrong about? Very important not to make knee jerk reactions to every "new" study. 2 Link to comment Share on other sites More sharing options...

I think if we get the earlier peak of La Nina the transition towards +ENSO may be pretty quick & hold some +PDO. We'll see. The “looking stellar” aspect of November (than waning out ) is kind of really what’s been going on as part of the climate change signal, with the folding hemisphere/early meridional expression stuff that’s being papered. … said papers being mathematical. As we get into December January February the hemisphere reaches its highest compressed state so the wind velocity in the interface between the Farrell and Hadley cells (steepest mean) reach their seasonal strongest… And that stretches the x-coordinate —>reducing planetary wave numbers …. which tends to pancake or offset rather, the meridional autumn… I was snarky last page… But in a more levelheaded approach I really don’t have a good feeling about this winter as behaving much different than the last several - which really all have kind of taken us through that journey every year with early blocks and high convoluted flow types tending to end up being fast and more “sheery “ I do acknowledge some caveat emptors, however. … willing to see how it plays out One, still not completely sold we’re not gonna have some kind of interference with normal stratospheric chemistry —> thermal disruptions due to volcanism over the last year. How and or if that even does so is available to question. I haven’t found any specific empirical evidence that the stratosphere was infused but who knows… Two, I’m also curious about the GRB that just took place - deep field astrophysical phenomenon. Though it was 2.5 billion light years away this actually set records for the most intense x-ray and cosmic ray burst ever recorded - not sure if that distinction is relative to that distance scale. But that’s what’s being reported. There was a defined ionospheric modulation when that event swept through our solar system. It’s long but known that sudden stratospheric warming events modulate TEC from the bottom up … Strong enough GRB event might “cleanse” some ozone population out if the PV column high up in the stratosphere anyway … 1 Link to comment Share on other sites More sharing options...

You also want cold waters hugging the AK coast near Canada during a negative PDO and it’s the opposite right now. It’s def negative overall due to the previously stated bath water south of Aleutians but not as negative as it has been the past few months. I don’t expect it to trend much upward either until this Niña dies out. 3 Link to comment Share on other sites More sharing options...

As the other poster said overa it is a -PDO by official measurements. But if you're looking at this & thinking typical -PDO at the moment ...then . This is fall & fall SST's can change quickly. So it's not indicative necessarily for winter. However if the warm waters remain in N. PAC & off Cali coast during winter there's going to be a lot of ridging out west regardless if it's "official" -PDO or +PDO. That's the point.
