ShawniganLake Posted January 13, 2018 Report Share Posted January 13, 2018 Yeah in 1996 there was cold air in western Canada that got dropped down. There is not a source of cold air to bring down as all of the coldest air is on the other side of the planet in Russia, it's not going to happen this winter. Time to start thinking about the draft and finding a better kicker. Next winter will be a wild card too. I predict weak +ENSO with one good regional event.But it’s an 08-9 winter. Those are always good. When aren’t our winters a wild card? Quote Link to comment Share on other sites More sharing options...

SilverFallsAndrew Posted January 13, 2018 Report Share Posted January 13, 2018 Unreal that Eugene had a 36" snowstorm. What setup made that happen? Gorge influenced cold northerlies with a Pineapple Express? I believe they had 47" that month. What was amazing too is that places like Florence on the coast had 2-3' of snow with 20"+ totals all the way south to Bandon on the coast. But yes, basically extreme jet suppression with cold air to the north. Silver Falls at 1350' had about 100" of snow that month with a 51" depth on the 31st.

Gradient Keeper Posted January 13, 2018 Report Share Posted January 13, 2018 Seems like a mostly reasonable take on things to me. Aside from the five snow events part.Anything is possible. Literally anything, except for 4 snow events in Portland. Then again, ya never know the end of January and into February could turn cold/snowy. It would be foolish to suggest that it isn't a possibility. It would be foolish however to expect it.

Phil Posted January 13, 2018 Report Share Posted January 13, 2018 The only reason I can think of is that western North America is more easily influenced by the seasonal cycle of the Pacific SSTs/ITCZ, and the Rockies protect eastern North America from that influence somewhat, such that temperatures east of the Rockies are more synchronized with those in the Arctic compared to those west of the Rockies.

I understand why the Arctic would lag the middle latitudes in the seasonal cycle, but why the west leads the east in the seasonal cycle makes less sense to me. What’s interesting, though, is that things flip around afterwards, as western North-American summers begin very late compared to the rest of the country, until you get into central Alaska/NW Canada, where the inverse is true. I assume this has something to due to the seasonality of the Pacific High. 1 Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...

Phil Posted January 13, 2018 Report Share Posted January 13, 2018 Maximum I suppose. I guess that could explain the difference.That’s fascinating re: glaciers gouging out the Puget Sound trough. The power these ice sheets had is simply amazing to me..how they permanently re-shaped geology in ways that define the landscape even today, and how “quickly”, from a geologic perspective, they were able to do it. The Great Lakes. The Hudson Bay. Long Island. All thanks to frozen water and cold temperatures. The Chesapeake Bay was also formed through seasonal meltwater floods when the rapid warming (4-5C in a few centuries) began following the LGM around 18kyrs ago. It must have been insane during those summers, to have a 20 mile wide, raging torrent of meltwater pouring off the ice sheet from June-August, then having it shut off and turn subarctic again from October - April. Not to mention sea levels rising up to 6”/yr. 3 Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...

Phil Posted January 13, 2018 Report Share Posted January 13, 2018 It’s actually one of the greatest, yet least spoken-of paradoxes in climate science today. Given the size of the Great Ice Sheets, even using the most conservative estimates, the amount of additional energy required to melt even 70% of that ice by the early Holocene (less than 5000yrs following the closing stages of the LGM) is so large it almost defies the laws of thermodynamics as we know them, given how much latent heat is absorbed during ice melt. Insolation, seasonality, and GHGes can explain maybe 10% of it. The only way to “solve” the problem is via a massive increase in heat fluxes from the cool, ice-age tropics. So much heat flux, in fact, that the corresponding increase in moisture transport/snowfall deposition would have to be overwhelmed by melting. However, that much warm advection would steal so much from the tropical heat budget, that the climate system would actually be losing a significant amount of energy while melting the ice, even after factoring in positive feedbacks like albedo loss and cooling high latitude oceans. But there are no alternative explanations than I can think of without resorting to hand-waving. There must have been a massive shift in the tropical/global circulation, perhaps a highly nonlinear response to changing orbital forcings, in order to terminate the ice age like that. 2 Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...

But things definitely got active sooner in ‘96. Not that much sooner. The 15th instead of 18th? Either way, anyone expecting any winter to follow another exactly will be disappointed 100% of the time.
