One thing I really hate seeing is we've seen a constant barrage of systems closing off and occluding across the Ohio Valley region...this has been a transition season theme for the better part of the last few years (more like 3-4). It doesn't seem to matter what the ENSO phase/strength is or what is going on in the Arctic, the regime favors closing off/occluded systems in the Ohio Valley.
I think this goes way beyond Arctic/N PAC domain and what is going on with NAO/AO/PNA, etc. One thing I wished you more of out there is research that didn't center on using physics and calculus to prove what is going on. I mean don't get me wrong, that component is critical, especially when it comes to modeling but I feel like alot of ideologies we have which center on how ENSO and teleconnections factor have not evolved much as these databases grow.
