Typhoon Tip

The PDO - as I read back in the 1990s ... - is often prone to ephemeral looks because of sea-surface wind stressing. Which makes sense, considering the PDO's domain space is pretty much overridden by the wildest, windiest tropospheric realm on the planet, ... pushing water plumes around and upwelling this and loading warm into shallows that. It's like one of those thumb-slide puzzles. Such that given to how deep the surface layering is (warm)(cool), either can be disintegrated instra seasonal and if significant enough, on scales of mere weeks at that. That lends to me questioning the usefulness of assessing the PDO in any given July through early October time frame, if one is to assess how it may look/be somehow correlative in ensuing winter. I wonder if anyone has ever took the scalar PDO of August and compared it January's ? Like -1 August = ? January in the "tendencies" - I bet the correlation is more noisy than we think... while biases the decadal signal... Such that if we are in the positive(negative) modes ... Jan tends to reflect the decadal signal, and August's throw out the variability. Thing is... momentum left over from spring may be mashed up with solar modulated summers, at a time of the year when/where said stressing is not as mechanical adding to the deception ... and that can falsely reduce(elevate) negative(positive) PDO's which ... btw, the "D" in P - D - O stands for "Decadal" for a reason... It doesn't mean "Dailies" ... such that a Aleutian bomb may neg the shit out of the domain up there ...but not really consistent with the longer term's vastly more correlatable decadal lags. Such that there's a couple faux negatives in Sept... a bomb in mid October that upwells, and everyone forecast a winter -PDO correlation that doesn't mean anything because the circuitry is all positive by Thanks Giving and stays that way until March. Just attempting to some healthy skepticism here -

speed/shearing is already observable ... Look at this flat baroclinic wave induced leaf on satellite - f'n haulin' absolute ass ...

Ha ... I wonder how much that is being pulled/weighted by the last 10 of that 30 years... Basically, wouldn't mind seeing that in 5 year intervals to gather an idea on trend.

You know... perhaps that is related to why the Atlantic Hurricane season ( thus far...but inevitably will end this way ...) suffered odd-ball MDR truncation of TC genesis due to easterly shear anomalies... In that sense ...and strengthened HC is driving unusually strong easterly trades due to it's growing mechanical influence on the global eddy - ... in other words, an SST modulation and sea-surface stress factor causing that...and may be mimicking a La Nina more so than a real La Nina. Maybe this is all backing us into a nice hypothesis for what the ENSO variance - it's always just been a kind of oscillatory HC ebb and tide in that particular atmospheric mode. When it is storng... easterlies tend to increase and that moves warm air west across the basin... and vice versa - ... heh.

LOL, why did you assume I was talking about Kevin Now THAT is funny. But... I was... hahaha... Oh well, they all do it ... this is an attention seeking thing for them.

When are you guys gonna figure out that it's all an act - and has been.... for years. You placate his entertainment ...as he gaslights people with absurdities so that he can recoup all the attention getting. Oh it's all in fun and good natured ...we hope - otherwise he's a sociopath, or just plumb dumber than a single-toothed hillbilly -

Hopefully no one ever did that - ...no, I've averred often in the past and over years that there are no 1::1 correlations in these teleconnectors: Earth, Air or Sea... certainly not in how they interact and cause synergistic outcomes. Having said that, that's not so one can go, "phew, I can still be ENSO reliant" - it would be unwise to weight the 300 year span of ENSO vs the climate impact model of the present era and going forward. How much so? That's your art - not mine. There were papers written about the recent warm ENSO events failing to materialize along expected climate impact routes... (they're out there in edu repositories - ) This isn't just my theoretical ranting - I am trying to bring this to general audience attention and have been supplying links - but... you know how that goes ..old habits - anytime there are abruptly dissenting points of views, the tribe knee-jerks in incredulity if not vitriolic stake-burning. Lol.. But, this is more like the internet causing bubble interpretations that are self-re-enforcing, where the agencies that own the information closer to the reality ...are often left on a metaphoric island while the party boat of faux ideology and those that act upon those doctrines ...sails away toward an enabling horizon where Trump demagoguery is somehow construed as a proactive vision for Humanity.... Just kidding - No, but ...as usual, the reality is a matter of fluid scales and degrees of mitigation - that's how this works. The ENSOs are "being" muted - they are not "muted" Sometimes it is seemingly absolute ( though would not be...); sometimes the limitation being observed appears to not be in play at all ( but it still is...). Everything is being subsumed or supplanted to some amount ...but above and below thresholds of observability. It's this simple: If the HC expands too far beyond the ENSO warm(cool) band, that weakens the ENSO as a "direct" trigger ... It probably becomes more "indirect" in that sense... the triggering gradient zone shifts polarward and the ENSO is part of the HC integration ... But, that offers all kinds of f-up crazy shit like sped up flow ( ding ding ding ...!) and arc PAC jets that tumble over and create unusually high frequency of -EPO ridge pulsations... enhancing cold loading at transition seasons... all this stuff can be mechanically rooted. The thing is... the heart of winter the polar hemisphere bottoms out seasonally and then the gradient and wind saturation becomes dominant as an impetus and ... well - My assertion of the NINA ...was kind of snarky for one. But not having much forcing is based upon a simple notion of arithmetic thinking - if the NINA is less than major, ...or, less than moderate, and in keeping with the above essence ...it should be more lost in the muting effect of the HC's having engulfed it so much so that it can't "trigger" through a direct gradient response ( which IS the circuitry) . I don't have any ego horses in this race and don't give a shit if I am wrong - but...I think this stuff offers a nice ( at least) entry explanation as why NCEP, NASA and Farm Joe's seasonal outlooks since 2000 have all been increasingly stinking pieces of shit... No one has forecasted ground-based airline velocity records and jet speeds so ludicrous as to wonder if the planetary rotation rate night even be getting effected by atmospheric torsional feedbacks! (Sarcasm) ... But what has become routine over the last 10 years... Yet, every autumn the same seasonal logic is gearing expectations .. okay.

I don’t think La Niña is forcing much. patterns may look coincidently like it from time to tine as the ‘unmanned firehouse’ happens to meander ephemerally thru the climate signal but tall N Pac arced jet’s likely to fold over either way from other emerging factors unrelated. The -neg EPOs intervals while ENSO forcing is subsumed and supplanted

That looks like the expanded HC compression base line frankly

I hypothesize that the Euro’s 4-D correction secret sauce doesn’t taste right when it’s mixing it up with global wind acceleration

OH yeah...wasn't that the year that it was like 50 to 70 F every afternoon until mid January ...when finally, the AO tanked on our side of the hemisphere the script flipped... I thought Valentine Storm was 2007 though and we finished stronger - but it may be eclipsed by the specter of the cosmic dildo flogging that occurred in the first half. I don't know.

Tends to happen ( lol ) when transporting -20 C 850 mb air plume over a still swimmable synoptic-scaled lake

Yeah that too - wasn't even thinking of bowling balls - but ... Case in point - does anyone remember that weird early October thunder snow squall event that hit Buffalo like way back there... autumn of 2006 I don't believe the ensuing winter (Will ? ) was particularly good or bad ... I mean that was clearly a rogue event/fluke like Scott just intimated... and was indicative of nothing.

Here's a thought - ... folding hemisphere/synoptics means early (late) cold shots... exciting snow chances at those times of the year - both anomalous for the last 200 years of date ( but perhaps not so for this present/immediate climate era ), but... since the mid winters are getting disrupted by speed saturation and R-wave progressive flows related to that ... it may be systemic to think of snow in October as increasingly likely ... while "organized" stormy and cold stable pattern deliveries as less likely in winters - period. And that those two circumstances are related because of fast atmosphere overall - but that does not mean they are connected by some other physical timing ... We used to debate pattern timing up at UML in Synoptic/FAST ...and we used to grudgingly agree that snow in October might be a poor correlator to mid winter, because of the normal gestation of pattern residence. There's really like three bell-curves there... a 10 day ... 45 day ... 90 day.... Patterns tend to 'click into temporal' cogs like that, before modulating to something new... Now, it can be muddled some by 10 days of pattern that flips... only to flip back ... so, which was it... Relaxations are part of pattern persistence however... and often the pattern's true residence has to be analyzed passe to determine that stuff... Anyway, 1995 was two 45 day long patterns ...interceded by a 10 day relaxation... ( example ) ... That's sort of what we played around with. Snow in October doesn't fit winter in any numerology of the bell-curve of pattern gestation/timing ... 10 days equates to a Rosby roll-out in early November... 45 ... terminates just prior to X mass ...usually in time for a grundle bomb too as though stalking that particular homage ... the 90 day might work, BUT, ...because October is the transition month...seldom can a stable R-wave distribution really be maintained through that inharmonious wave time of the year...making 90 days ( 45 for that matter..) less likely to occur beginning in that month. In effect, October is kind of in no-man's land. But, again...that is based on the traditional data set ...which I think is in the process of being significantly changed due to the last 15 or so year's of behavior and probably going forward in this climate change shit.

All the while negating the morality of deception douchery alone the way -

We just had a shot across the bow low top gusty shower ... A month from now... that'd be light rain --> grapple ticks --> aggregate noodles --> light rain ...back to sun... The sky had the texture. The rain was cold ..brr on shorts legs, going sideways in 30mph gusts. It was a CAA driven instability in other words and we had yet to see that this early autumn ... so it may be more than merely symbolic - But ... mm, it's funny that despite the ensembles the operational models are fighting their own means for mid month. I'm not sure I buy it just yet... The GEFs - fwiw - still signal an early winter like pattern expression. We could almost argue that's so anyway, with 540 dm thickness contour down to the N. Lake and N NE at times prior to this the mid month 'warm up' ... But now we got a canes crawling up the eastern seaboard with 19 c 850 mb thermal plumes ejecting out of the front range of the rockies on top of the GEFs +PNA/-AO(-NOA) hemisphere. Interesting. Could also just be typical transition season growing pains -

I wonder if those correlation arguments or points are reducing in value anyway... If this speed stuff and the folding of the atmosphere at large scale, causing book-end winter expressive patterns that yield to internal seasonal gradient saturated craziness has merit... Those correlations are based on a heredity that may no longer be valid. So, while they may not be entirely moot, their usefulness questionable.

cold "snowy" October - where it the f is that coming from -

Excellent question ... I am not expert in this area of Meteorology - I'm sure there are others lurking that may have some better refined information, but just off the top of my head .. pollutant aerosols do have an effect on both incoming short wave IR, and... outgoing long wave IR. That much we know ..but it matters which - Some aerosols trap that outgoing radiation resulting in net heating over otherwise free air. Some aerosols are 'reflecting' and actually act like a block of solar energy ..such that multiple wave lengths or just a few/some can get through and/or are prevented. Sulfur-dioxide is a huge block and can cause global cooling... There is also an altitude/suspension for the efficacy of each aerosol type's ability in any of these senses. Ex. Sulfur-dioxide contaminant in the stratosphere caused the year without a summer ( theorized ) post the Tambora eruption of 1815.. Smoke penetrates multiple layers of the troposphere and can get into the stratosphere ( eventually) too. My hunch is the smoke particulate aerosols are more in the blocking aspect as opposed to the trapping outgoing IR/heating... They behave similarly to cloud cover in the sense of increasing albedo - reflecting/shading...etc. As an aside, I'm intrigued by the pervasive early autumnal color flushing that's transpired Lakes...OV down into MA and in NE regions as 'plausibly' connect to late summer dimming these region experienced as consequence of excessive smoke as you noted - and that would be consistent with blocking UV and perhaps triggering the foliage early as (hypothesis...). How/what/if that effects winter ... hell if I know. October and onward into winter ...we are entering the time of year when 'blocking' at 60 N becomes substantive anyway. Added to, during a solar minimum which has some correlation with blocking, plus...during PDO/AMOs that both correlated to -EPO(-AO)-NAO arc on our side of the hemisphere ... All these latter factors are in play... While ( if that were not enough) this velocity stuff might be related to continental "tucking" and increasing cold loads into Ontario as described ... I mean, separating causality is a difficult parsing exercise in all of that. Smoke? heh - The short answer is it effects.. how so? My own speculation is that it increases albedo and may net in cooling but.. it's also not clear how homogenized the smoke is and if it is enough to infiltrate the entire hemisphere substantially enough to matter ...

Can someone move that the October post in here ? it's still relevant... I'm actually wondering if we are already seeing some pings on the extended radar -

Man ...that'll really set the pumpkin fields aglow in the dawn light over the weekend, huh - 546 dm thickness, whilst pervasive high pressure all over southern/SE Canada spills into the Lake/OV/NE region ... offers perfect light N oozing that terminates into decoupled low levels, That has a 22 to 30 nocturnal rural frosters seeming likely.

oh crap - I thought I started this thread already with a write up about October .. but I just realized I neglected to actually type October in the title of that - lol..... oops

Bingo! Yeah they're a gov org - they can't make supposition? Not without huge problems - lol... So, yup ... I don't mind the 'leading prose' ( if you will ) so much, if at least it can be vetted through a modicum of analytics... which this does! Both apriori but education combined. Anyway, for the general readers, I love their ( apparently negative rendering when copy and pasting) image acuity and simplicity as reference ... Keeping in mind, I think these base-line states are being disrupted by the expansion and velocity stuff as we are describing... So, perturbing and adulterating these looks ... yup. how? million dollar question. I strongly suggest that the straight up ENSO statistical correlations are in trouble... We've had modes on either side of warm(cool) in the last 12 years with apparently limited impacts around global notorious climate zones .. but here is the base... Know what is funny about this... It's odd to me that our best snow winter comes at like +.2 NINO regimes ? when this image smacks as though -1 would be the big nuts... Interesting -

That is the SST correlation with the wind pattern stuff.. https://science2017.globalchange.gov/ ... corroborates as well, and discusses the atmospheric modal changes that have occurred in the past 30 years as part of this total response in the global hemisphere - Hadley Cell is an atmospheric eddy that girdles the tropics and subtropics around the planet...featuring ( in the means...) rising air near the Equatorial Monsoonal Trough zones and augmented by MJO ... etc..., polarward mass flux from convection deposition in the high troposphere, and downward ambient flow tendencies in the midst of subtropical ridges ... On the polar side of these ridges, the flow terminates to the westerlies band, the demarcates the interface between the Hadley Cell and the Ferrel Cell, which is the polar cell that orients at higher latitudes ( lower if talking about the southern H. ). The HC expansion is noted in the atmosphere - Refer to chapter 5: 5.2.1 Width of the Tropics and Global Circulation Not to laboriously reiterate but...the expansion of the HC is butting up against the lower Ferral Cell where cold hypsometric layout and compression resulting, is causing enhancing wind velocities as the balanced geostrophic response. In fairness, the article/content may not describe this latter wind response outright - and I have been clear this is my own hypothesis, but it is a damn good one! Regardless of refutation as to cause, the previous "stable" climate R-wave climatology is in peril during colder seasons, because wind speed in the wave mechanics is physically instructive regardless and we have had velocity and gradient saturation ...regardless of ENSO and other factors - it's become a base-state. ... Couple of plausible examples of altered R-wave climate: NAO blocking rarefied because blocking constructs are inherently more difficult to maintain in excessive X coordinate wind. Also, tending to fold the top latitude flow over mid latitudes, earlier in Autumn exaggerating early cold loading into Canada, as well as upon exit in springs. So, if we negate this shit in our seasonal outlooks and/or even modeling -based weekly forecast visions... good luck .

Would anyone happen to know where CDC is hiding the PNA/NAO/WPO/EPO product suite ?

But that link is an endless maze that frankly doesn't appear as though any engineering effort really had user accessibility in mind.. Am I simply overlooking - or... I am toying with the notion - either way - that this is just another example of bleed-over incompetence from the cultural influence of a kakistocratic government apparatus that swept in upon the election 2016, which began stripping institutions of wherewithal. Consequently, there are less professionals there that either care, or, know what the f* they are doing -
