I've often wondered if going to coarser and finer resolutions has had some sort of negative feedback...but maybe the positives outweigh the negatives. 

I suspect two things are true at the same time, and they are competing..

1  ..the models are vastly improved over where they were 30 years ago. Now ...that may have slowed down in recency ( last decade or so), sure... but they are still more powerful for computing speed and density of sample/grid intake --> physical processing than ever before.  We need to just accept that. And they are not 'doing something different' while they are at it ?  People seem to hint they are 'suspicious' or something. I'm like, yeah...of what?

2  Speculative ..the patterns of cold season hemispheres is different than it was 20 years ago.  It just is... be it CC or not (related), the observed patterns enter into inherently poorer predictive states by breaking down at faster rates.  Wave propagation mechanics are having tougher time in a continuity because the proverbial rug gets pulled out from under the pattern scaffolding so quickly. 

So what's going on is that we are with improved technological capacity that is just being stressed to the point where they can't perform as well as if these model advances were to have been set into practice 20 years ago.

Great post, well said. Couldn't agree more. This is a pretty darn good way to state things. 

And what I have bolded irks me too. It's not that models "change". I mean when you think of it, the solution the model is spitting out is the product of how the pattern is evolving (time step derivatives, leap frog equation...I forget what that was called. Did that in mesoanalysis. I remember one Thanksgiving morning tackling that homework assignment). So feasibly, the solution the model is spitting out is correct...assuming the evolution occurs that way. 

Ultimately though, I think it just comes down to expectations and we let emptions get in the way and then all hell breaks loose.

Lol call it what you guys want…nobody is falling in love with dumb ass clown maps, or saying because the euro showed a snow storm yesterday and not today it’s worse. Ultimately it isn’t as good anymore…ya can take the scores for the Himalayas and for the Gobi dessert and burn em..the model has lost its mojo. 
 

Sure, the GFS is a lot better now, but it’s still not as good as the Euro was 8 yrs ago. As somebody said..to sensitive now is probably the case, I agree.  
 

Moving on…I guess we wait a little longer in SNE..

I liken it to people reminiscing about their 1990 Mach 1.  It was great for it's time but are going to trade your current 850?

P.S. My back hurts just looking at the suspension on the 1990

Won't you guys adapt the new strength and weaknesses of the current models and adjust forecast based on that?

I get your point, but this is Not quite the same Mark…but great pictures.  
 

Liken it to an 11 year old 2013 XRS 800, beating that more than a decade newer brand new 850 in everything but comfort and looks, but then saying well the styling, the seat and instrumentation is a whole lot better on the 2024.   That’s what this seems like.  
 

But who cares…I know I can’t have any confidence like I used to in the Euro anymore, in the 96 hr and less range, like I did 5-10 yrs ago. And that’s all I know.

Imagine how completely boring it will be if and when the modeling reach infailable levels one day down the road... There would be just one centralized forecast office manned by a person to activate the computer and a janitor to dust... Also it would spell the death of weather forums! Lol

It would…but we’ll all be long dead. It’ll suck for the weather geeks at that point.

I tend to agree. These next few weeks are hostile for most in SNE in the best of times, never mind this current climate regime.

 

The shit sandwhich first week of December was always the most likely outcome.

Lets just hope we aren’t watching the Ball drop with nothing to show for the month.

It’s been frustrating the past couple winters when the good pattern comes in Nov or Mar/Apr. i’d ideally like to see it come 12/20-3/10 in order maximize climo. The season is getting shorter anyway so let Jan and Feb behave like the way it should.

Yeah understanding the strengths/weaknesses of models should certainly be factored in. One example of this is with forecasting temperatures and using MOS. We see this very often during the spring months, but MOS tends to struggle mightily when it comes to highly anomalous patterns. When we see an anomalously warm airmass in the spring, MOS can underdo temperatures badly. See this often in the heart of the country too...sometimes MOS will miss in places by like 10-15F

Wait until quantum drive technology powers the weather automation grid. 

Wont be modeling anything

I thought Google or some company was working on a new model.
