Typhoon Tip

Several observations about this graph... 1 it's too bad the x-axis ticks stop at 20 year intervals. I'd like see which months these individual points correspond to. I'm wondering (say) if the spikes are more common in the autumns. Or perhaps spikes in general are more common during transition seasons. 2 there is a "similar" magnitude lurch upwards in global temperature that took place just prior 1880 in terms of total d(T). There are also rather impressive dips that some 80 or even 90% of this Septembers scalar delta that took place 1900, 1960 ... 1995 (Pinatubo?) ... Anyway, 80% of 1::10000 chance of occurrence seems too steep considering what's taken place several times in the last 150 years. It depends though ... The 'odds of occurrence' may fall in some sort of log(x) decay ... Such that the top 20 or 10%s compared to the bottom 80, the odds get very long. 3 regardless, the trend is alarming. There were two accelerations: a modest one around the 1930s; the one since 1980 is fascinating in that the low points along the accelerated rise, are usually about the same as the previous high point - hence the 45 deg slope. But, what that means is there is never a step back. wow

That pattern now is completely meaningless to later Novie onward Zip indicator

Chilly though... Swap rain for 52 clouds and NE neck caressing "balm" ... Just enough to keep hands cold. Seems the pattern is manifesting a cool eastern continent ... without really any obvious feeds of lower tropospheric cold sources. Yeah there are those pretty blue hydrostats showing up on the sfc modeled synopsis' mid Ontario, but they stay N. The sfc mass-fields trek E while staying N of us (the season isn't matured enough to send them SW of us just yet). But with the sun feeble now, getting these muck morning cloud types with still air (when not E w), the atmosphere isn't recovering, so it sheds therms slowly. We just end up raw... I'd like a dry series of days in the upper 60s or 70, for 7 to 10 days before this antic claims this month as below normal by fake means. Lol. I mean there's no such thing as fake ... I just mean it's coolness that's manufactured very locally by idiosyncrasy rather than a very obvious large scale continentally involved CAA regime. It's not too much to ask in a world that carries on over the top of a CC hot plate?

A pattern tendency conformed to warm ENSO climatology should also then be modulated warmer in the temperature predictions. These Global oceanic thermal sources will overwhelm atmosphere thermal sink/sourcing. Cold will attempt to pour into the continental geography given +PNA in such a regime but I suspect these to cede to very handsome return flow recoveries, do to the background imbalance above. Larger transitions also aided along by +geostrophic wind velocity anomalies. Predicated on the risky assumption of a coupled base to atmospheric observation, one extending into and modulating the R-wave distribution would be preferred. I’m not sure this NINO will be that instructive tho. It could get lost in the maelstrom at times - one week it looks like it’s the lever and the other week it all looks like something else.

‘Cept we haven’t had that many (if any really) real coastal developments. There’s been a lot of modeled coastals in the extended … we’ll see how it plays out. At least the models see that as possible - does have some value.

that’s a moderate coastal at worst

I think Bill Belichick’s been overly exposed and I don’t know why it’s taking the Krafts so long to realize this and move on

I thought last week was rock-bottom for this patriots team, but… Man, it’s like they expanded the event horizon of the cosmos of suckirude in order to suck even worse

63/47 full sun in something like 354 billion mile visibility purified air mass. in fact… the absence of impurities in the atmosphere smells unique today.

It’s not a death knell anyway… Even though the preferred state for negative EPO is to have a negative AO as well, but those two share domain space - there’s a partial disconnect. There’s been plenty of times in history whence a negative EPO set the temperature anomaly table across North America downstream, all of which took place with an AO that was closer to the neutral, or even positive.

Based upon the Antarctic study ... it's taken time to penetrate. This isn't wildly speculating. It rational enough, but as I said, it is also in a science now - I was careful to point that out. You know, for you seasonal hobbyists .. .it is a game of 'what can go wrong' - from out here in the spectator bleachers, it certainly seems that way. Lol. Anyway, it'd be nice to once in a while have a clue where impediments may come from. I think the ENSO and arrival and the +AO; that seems like a potential systemic variance and a pretty good place to look. The problem with statistically based approaches to interpretation, it really comes down to calibration vs discrimination. The former more analytic, the latter is how we subjectively consider the ranking. We can and sometimes do falsely rank, usually because we're motivated to prove the correctness of our hypothesis, more so than the fallibility of them. This gets us dangerously close to cherry picking... Wtf am I babbling about or, the discrimination aspect is in trouble this year - I would suggest - if the ranking ( subjective or not) isn't considering what took place in the Antarctic, and that it is presumably so to be the case in the PV on this side of the winter globe. or not... but it's worth consideration.

For general audience ... a cooler PV domain would result (geo-physically) from a WV contamination, and that quite obviously and directive, results in a +AO. The MJO/warm ENSO correlation is a -AO. So that would imply a statistical break-down wrt these large scaled mass field projections on the winter. That may also infer a negative interference in the intra-seasonal pattern modulation-behavior. ... Something's going on in these PV - see Antarctic. Recent analysis of the "Ozone Hole," after decades of recovery since CFC's were reduced, there is a surge in the size of that behavior, most likely (in science right now) attributed to the Hunga Tunga event. So there's some plausibility as yet to be substantiated, but the reasoning in how it may effect a PV circulation mode during the winter would preliminarily (though increased confidence), suggest +AO base state. Just fwiw -

Noticed three aspects about the rain this next weekend over the last day(s) of modeling. ... tendency to delay ...tendency to suppress ...tendency to weaken All of which can be a part of what I have phrased "model magnification" in the past - more specifically, as the 'de'-magnificaiton correction than ensues in future runs, the above list of morphology tends to occur. So to spell out the metaphor, when events first emerge out at the outer temporal boundary of 'practical' distance ( beyond which the randomization is too large and overwhelms confidence ), the specter of what the model result is at that point in time, tends to be more amplified than what will actually occur. All guidance do this. GGEM ... EURO ... UKMET ... GFS ... JMA... Kevin's imagination, I have not seen any one of these sources free from blame. The reason they do this, they "see" future events as a result of present input interacting in the processing of the physics, but cannot see all the permutations that have yet to emerge in time. Some of which directly negatively interfere, but some actually require wave energy of their own; sapping off the domain ... effectively robbing the original specter of what it needs to maintain - this may just be another way of describing negative interference.. Either way, the result is the reduction over time. It think it is a natural artifact of the technology. One that perhaps cannot be avoided, too. Maybe in the future ...all the doubters of 'flying models' will eat crow but until models can see the catalogue of events that are going to happen (will of god type stuff), those "permutations" are yet to occur as part of an uncertain future. When a given guidance sees a big D9 event, it's just not seeing all the other hindrances that will manifest in time that either cancel or rob, cannot be predetermined. If we further that thinking ... we may be nearing an end of what these models can really do for us in terms of "really" predicting the future. I wonder if there is a way to calculate the "uncertainty of emergent future properties" as a function of time - so it grows... Then, at D11 (say..), we might benefit from knowing that the very best the models will ever be able to do, given the atmospheric domain in question is 57% accuracy ... This type of imagined analytic approach would not rule out or suggest the blind dart scenario, either. It only says that no matter how well a guidance or a person visualizes D10, once applying the 'uncertainty coefficients' they or technology could not have had more than that 57% certitude. D5 improves to say 77%. D3, 97. Daught, hilariously sounding like 'doubt' now-cast is 99.99999999... because there is always some subjective error that is too finite to be seen. The whole model would eerily agree with one of the baser tenets of Quantum Mechanics, that states that an object cannot be simultaneously measured for it's velocity, or position, in space to exactitude. This was going to be a small post ... I've gone and f'ed that up. I guess if you've read this far, bravo. But the original intent was to say that those three aspects above are trying to save Saturday.

Call in the family ...

The winter fantasy thing isn't without a modest amount of pragmatics, actually. That is a winter pattern. It's just set upon a canvas where the heights and thicknesses are about 30 dm higher than ... what we used to experience IN winters before we sold our souls with the currency of Satan's blood - oil. But that's 'sides the point Seriously though, that is. It's good to take note of that Euro ( 06z GFS caved into that look considerably, too -). The usefulness is working out the rust and lubing up the tracking gears. In the heart of the winter - I'm going be concerned about gradient saturation and too much velocity in both ambient westerlies, but also how much the atmosphere converts that wind abundance into actual wave propagation speeds/mechanics. The latter's been a shearing tendency in recent years with this problem...

Snow by Halloween ( yet again ...) isn't just a GFS operational fantasy. There are non-zero useful predictive metrics that signal what's become ( what I think - ) a recurrent autumn facet of CC during these early 20 ... 50 years. And that's a tendency to fold the flow over continents earlier than normal. There is so much latency of heat below 50 N around the hemisphere that the physical instant the Boreal winter season heights begin to fall, there is a subtle but all important stronger than normal jet response. The western aspects of continental geology then bends the flow into ridging potential, ...which during years whence there is a +PNA tendency, together creates a non-linear but very real constructive interference. Boom! Early cold synoptic interludes. I certainly would not recommend wiener-ing oneself over these extended GFS solutions. However, I would definitely warn that everything ( plausible above) is in play and test. This is going to happen in autumns going forward - op ed. This is also new climate tendency/paradigm that does not fit into traditional ENSO this, or polar index that. Those index modes may or may not be favorably coincident - when they are/not, there's constructive or destructive interference, respectively. But it's very hard to parse out contribution from either. This year, I would watch for +PNA mapped over top this 'folding tendency' ... Then as specific events materialize during those last two weeks of October ... we then deal with "model magnification" - in fact we're probably already looking at that in those fantasy range GFS looks.

haha.. 00z Euro spanning next weekend takes all the shittiness quotient of all these bad weekends, extracts their essential oils, and brews up flavor of shitness 10X's more repugnant than any of them...

I studied it for 10 years and I found there was a definite positive correlation with the d(d(cryo). In other words rate of change, more than if it is adding at all. The problem is I had to stop because the land snow entry times were pushing later in the year. Some were mid way through all of September before the snow accelerated in land coverage which skews the data set toward irrelevant if I have wait until the f month of October itself. There may still be a correlation ... in fact I suggest there is. But I haven't bothered to slide the time range to include more of late October and November, which are already (technically) too late and intra-cold season above 65 N. The purpose of the analysis was "leading" indicator.

True ... however, these planetary spikes predated those theorized geo mechanics. Right? I'm pretty sure this all began at the tail end of February and particularly throughout Mar/Apr. This was before OHC was in any kind of coupled state where it would. Meanwhile, the N Atlantic above the tropics flashed warm - 'what does that have to do with OHC from the tropical Pacific that doesn't exist yet?' It doesm't line up very well temporally. I was discussing this in the climate forum. It appears ( by observation alone) that there were concurrent phenomenon taking place. One unknown ( above), with one known - this latter of which may yet add its juice to the punch.

Still ... for me, I like seeing the 540s hydrostats atop -2C at 800 mbs arriving on the NAM/FOUS grid. Hearkens the spirit of the season.

Managed 81 here... Fog slowed matters earlier but we seemed to have made up some ground

Yeah, this synoptic evolution incoming is completely new ... Should not be confused or compared, or assumed to be a part of the stagnated wet/humid/warm persistence of the last 90 days. This is a wholesale new pattern orientation that is setting up because of an obtrusion of +PNA. The restructuring of the pattern is taking place with rapidity, and this storm that winds up over Ontario and the colder regime coming in underneath and all that, is completely uncharted waters. Anyway, the behavior of this isn't like a slow moving trough along 90W with a persistent PWAT delivery. It's more like an active frontal boundary that is tipping negative but will progress quickly through. It may rain hard along an axis (est Berkshire/Greens) but it's outta of there probably in 4-6 hours maybe faster. Showery everywhere else. I'm actually wondering if we may see a low top ribbon echo squall or broken feature thereof, with some heftier wind gusts. There may also be a wind burst in the back side as the pressure well deepens and cuts W and sends an undebelly restoring force across NYS and C/NNE. I've seen louder signals for that, but there is some look about this.

I will say that I lean a lot of ballast in the direction of RONI studies ... Perhaps a personal bias for the fact that I conceptualized something quite similar many years back. That said, it's probably got blurred forcing boundaries. Thresholds here and there, that have to be estimated, or less than discrete in general. Who knows? Right.... like, 20 ... 30% of the ENSO warm legs are chopped off, because ENSO is wading in a pissy world already ... making a 7' monster more like a 6'2" tall guy. What's funny is that the 6'2" guys tend to actually jump the highest - ... fun metaphor.

Too much attempt to target specific oceanic regions as causal in x-y-z pattern tendencies. This is now a relatively new faux methodology that's coming about in social media and Tweets from big reputations, and it's not right. Perhaps not the intent, ... but it sure comes off that way. If we wanna really skeptic as scientist ... the whole flapping oceanic planet is +1.2C on average or whatever it was as of last check. Pretty much in every direction and region, save for small seemingly irrelevant cool offset upweller chimneys. And that would seem intuitively a big red flag not to trust any of it - worth of empirical test and geo-physical review.

This appears to be a pan-dimenson hemispheric scaffold change. Every index from Japan to Greenland is connected to it, and the PNA is the most telling. It is correcting from -1 to almost +3 SD in a matter of mere days. To mode switch a domain space that size that quickly is highly unusual. Some sort of correction event in the heart of the winter would be dialed up by either a series of imports, or ... one giant ordeal. ... In early October, this is unfortunate for storm enthusiasts. The ambient baroclinicity is absent given to seasonality. We may plumb truck loads of 500 mb potential into the 100 to 90 W longitude with limited means to really drill it into the lower troposphere. There is some attempt on the first in the series that gets tangled up with Phillipe's guts. The GFS in particular goes from 990s to 970s mb drifting west of Toronto.. btw, I'd watch for a backside isallobaric wind burst when that bag of low pressure bombs exiting N across C/NNE in GFS recent solutions. Euro's been tamer.
