brooklynwx99 Posted March 1, 2023 Share Posted March 1, 2023 the EPS and GEPS are in absolute lock step agreement with every major pattern feature and then you have the GEFS in left field picking its nose. idk.

Honestly looking at the loop on the Gfs these last couple days it’s as if the subtropical eastern N Amer ridge is more cause than effect. That evolution makes sense if the SER is acting like a mid lat block itself. We don’t factor it that way because during winter that heat source has never been strong enough to bully the mid latitude jet but maybe that equation has changed? If the SER is a cause not an effect it really changes things a lot! Im just speculating here. But the Pac western US wave spacing is absolutely absurd on some of these Gfs runs ETA; to clarify what I mean here, a great pac would obviously still obliterate a SER. But what if the SER is not ONLY an effect but equal parts a driver? Would explain why there is almost no variance lately. We have had some brief periods this winter where the pac forcing was temporarily reversed or in transition and it made little difference to the SER. Expand I've read from pro mets that the SER is enhanced by the record warmth in the MC of the W Pacific in addition to it being enhanced during La Nina. But is the SER also made stronger by the AMO? The AMO has been about as high during the last few years as during any other period: https://psl.noaa.gov/data/correlation/amon.us.long.data If the high AMO, itself, is also a significant SER strengthening factor, I could see your idea being plausible. Could it be that the overall warm Atlantic (including GOM) from the equator to 70N (one definition of the AMO) is resisting and thus providing its own blocking (manifested by the persistent SER)? 1 Link to comment Share on other sites More sharing options...

But honestly by day 10 I like that look better than the stuck in between look of 12z. It allows the conus ridge to back into the SW. It’s cold but dry unless we get something to dive into the east but in March that can work sometimes. Certainly not as good as the euro progression. Crazy worlds apart starting at like day 6.

The atmospheric longwave pattern is made up of ridges and troughs, the existence of which serve to maintain heat balance and conservation of absolute vorticity. The phase of the pattern will shift(and change the relative location of the troughs and ridges) largely due to drivers such as ENSO. At this point I still think the SE ridge is largely an effect- in this case the downstream result of a persistent upstream Aleutian ridge/-PNA blocking pattern in the Pacific. There are possibly other influences that contribute to the seemingly 'easy development' and persistence of the SER in recent winters. Not to be discussed in this here thread though.

Expand 90% of the time the pac and SER have been coupled. But what vexes me are the rare times the pac was altered lately it didn’t matter. Look at what’s coming. This strong mjo wave in 7/8 is having an impact. 7/8 isn’t ideal in March but it’s way better than MC forcing. You can see coming up it’s able to alter the pacific into w more convoluted configuration. It’s not omg great but not totally hostile either. The crap base state is resisting but it’s as altered as I think we can hope for. But I could take a snapshot of various points where the ridges and troughs are in different locations in the pac yet the SER is the feature that remains constant on the Gfs. The ridge is less emphatic than when it was being fed by every longwave feature for sure but it’s still there. So something else has to be part of the equation. As for not talking about “that” how far does this go? We don’t need to discuss AGW to speculate here. The entire Atlantic basin is on fire. That’s not a climate change debate that a right now reality. Not being able to discuss what’s going on RIGHT NOW is ludicrous 6 Link to comment Share on other sites More sharing options...
