Torch Tiger Posted December 10, 2023 Share Posted December 10, 2023 Winter *SHOULD* perk up near/after X-mas, who wouldn't forecast that happening?

That's really all I can speak of and address. If nothing is happening short term besides a wind/rain/far interior elevation snow in the near term, all there is to discuss, besides that, is medium range and beyond forecasts. Pimping ensemble products? What does that even mean. I don't know too many people who don't use ensembles for 500 mb pattern or things like the NAO, ENSO, strat warms and the such. I like mets discussing those things because I am weak on my correlations and thus like seeing discussions on them. 1 Link to comment Share on other sites More sharing options...

If something in the base state has changed, maybe warmer oceans globally, empirical based predictions that worked before won't work as well now.

If something in the base state has changed, maybe warmer oceans globally, empirical based predictions that worked before won't work as well now. "those forecast" in deference to the above are a mean of all the ensemble members. They literally take the average of all the ensemble members. Each member has slightly differing physical equations, but they are not 'guess work'? I'm not sure precisely what you mean by "empirically derived equations" but ... the physical equations built into each do not produce impossible solutions. They wouldn't be of much use if that were the case. Each focuses in a specific aspect of atmospheric physics. There's probably documentation on each member's "genetics" ( if you will). Ho man - can you imagine the Asperger spectrum required to read that? Like Member 6 uses some experimental convective sequencing - now ... go and match all those days whence ever those were valid, and if those valid days match the circumstance at hand... weeee. Popsicle headache. Meanwhile member 7 ... some other variant, and on and so on. This stuff actually matters, because the thing about cloud creation (efficiency/proficiency: That releases latent heat during the pseudo adiabatic machinery of the storm, which if done by X physics may or may not be more correct than if done so by way X', or Y or whatever. The operational version's just employ what's worked the best in the past, through objective comparison with reality through experimentation. I may be butchering some of this but in principle that's the gist. Having said all that, the individual ensemble physical implementations don't change ( unless a wholesale new version is rolled out). They're just process out into the future based on whatever is given them. Which is the initialization provided by sounding/satellite Link to comment Share on other sites More sharing options...

Typhoon Tip Posted December 10, 2023 Share Posted December 10, 2023 Yeah...I suppose being 200+ hours this thing oughta be watched. It's not mere noise in an errant operational run there. This thing has heredity going back days of runs - granted with the usual inconsistencies to be expected, the essence has persisted. Earlier I spoke of the +WPO/+EPO unfortunate motif that's recently evolved... however, the +PNA during the period between D6 -10 has also been there all along. The modality of which does send some correction signal/H.A. Obviously, this social media ilk of folk don't care too much for powerful WARM Miller A cyclones getting captured by the N/stream, only enough to slow it down while being too late to save Christmas nostalgia - understood... But should the synopsis over SE Canada morph in the right direction that profile could easily change 2 Link to comment Share on other sites More sharing options...

40/70 Benchmark Posted December 10, 2023 Author Share Posted December 10, 2023 The crap pattern will change....maybe Xmas will be 50 degrees and maybe it will take longer than many of us had thought...maybe it won't. But keep in mind that periods of flux will often feature marked volatility in the extended range on guidance, so try to take a step back and wait. Look how everyone was spiking footballs for a time about December prospects when we were transitioning from the cold November regime to this. Even @raindancewxisn't calling for a blow torch of a winter, as his NE snow defecit is more tied to a flukey seasonal precip hole based on -PDO analogs, which is far more precarious and correctable than a 1997-1998 redux. Just enjoy the holidays, play in puddles and go with the flow. 4 1 2 Link to comment Share on other sites More sharing options...

I sort of expected this in Dec. If we’re seeing this a month from now, different story. Yes to both. But even then(1/10)…Things sometimes don’t get going until after that. But it will be more concerning for sure. Not saying this is 2015, but that season had a blast furnace Xmas, with zilch until Friday, 1/24 when we had a wet snow 1-4” on a Friday night, and then the 0z euro brought back from the dead the blizzard for that Monday, 1/27, and then it was off to the races. So many times, it just takes an excruciatingly long while to get going. But I think we all expected this here in December. 1 Link to comment Share on other sites More sharing options...
