If I’m not mistaken a bunch of the -IOD/Nina years saw -NAO/-AO in November. It looks like at least early November is going to start with a weak SPV
-
@Bluewave Thought you might find this interesting, it ties ocean current cycles in. Think arctic sea ice and solar also playing a role…
-
I absolutely believe the seasonal models that this is going to be a northern branch dominated winter with a very muted/weak STJ. The deepening -PMM and Nina supports that projection
-
@Gawx This has been quite the solar and geomag spike since August
-
If the projected AK/GOA trough pattern continues into early November and continues to cool and erode the “warm blob” then we will have a real big SST analog divergence with 2013. Early November 2013 is when the warm blob came back with a vengeance and the PDO flipped into a Victoria mode and stayed locked in through the end of that winter
-
If this pattern continues into November, at least as far as the “warm blob”/2013 SST pattern, it’s going to be real difficult to continue to use it as an SST analog. The warm blob came right back in early November, 2013 and we went into a Victoria mode PDO for the winter. So far, the cooling has not reversed over the last month and is continuing….

The one main staple over the last several winters besides the negative ENSO tendency and reoccurring MJO phases has been the marine heatwave in the NW PAC around Japan. It’s been extremely anomalous

This current -IOD is the strongest in 17+ years
-
@Bluewave This may end up being the strongest storm/low in history for the Bering Sea….almost 950mb

It would not call this a pure east-based La Niña. Not CP/Modoki, but this does not look like a 2017 evolution, which was a true east-based event
-
One important difference is the AAM. Last year at this time it was in full on El Nino (positive). This year, it is and has been very strongly negative
-
I still won’t be surprised if we finish around or just under 100 ACE for the season. If that happens, like I’ve said, using factors such as La Niña/-PDO/-PMM/+AMO, warm MDR as justification to predict an active Atlantic hurricane season need to be re-evaluated. Maybe things like solar cycle, etc. need to be figured in. It’s akin to how some were using the amazingly persistent ++AO since spring to argue for some big arctic sea ice recovery, which didn’t happen
-
All you have to do is see the names and look no further….BAMWX, Mark Margavage, JB, Henry Margusity, Tony Pann, Mike Masco, severe-weather.EU…and you know it’s going to be hype about a very cold and very snowy winter
-
NOAA/CPC has upgraded to a La Niña advisory today
-
-
-
Yes. I saw a study (probably the one you’re referring to) years ago that tied IOD forcing into the WPO
-
I don’t think anyone on here at least expected anything more than a weak La Niña
-
16-17 was strong -IOD and a +NAO winter
-
-
Seems like it happens every year for the last several….this shows up in October/November, never to be heard from again until late March/April
-
The way X is hyping this as a classic extratropical “nor’easter” is totally laughable. It very clearly has subtropical characteristics and should be classified as such
-
Isn’t the point of this board to discuss all different ideas? If it’s that much of an issue, just say the word and I won’t post on here anymore
