  2. Everybody here is too old for this reference
  3. Referring to the March 7 2018 storm? That was way more painful for me than it should have been. I still believed in dynamic cooling then…
  4. Every weenie has a storm which teaches them to emotionslly disengage from modeling output - mine was March 14, 2017. Not in the same league, but 6 inches of pure crust is highly disappointing after a D5 14” EPS mean prog.
  5. Oh it’s a hemispheric thing, makes sense. I imagine 3-wave patterns are higher amplitude because the same amount of energy must disperse across fewer total fluctuations, therefore each fluctuation is greater in magnitude. Can any met verify this line of thinking?
  6. It would be ideal to have an AI that finds all the five-day periods similar to projected five-day maps for analoging purposes
  7. There were also a few events in December as far as I can recall. Very solid winter
  8. Me and the missus get back from Iceland on the evening of the 24th, so hoping this becomes a boxing day redux
  9. My instincts tell me to close the curtains till after New Years
  10. Yeah, regio beta paradox. Institutional entrenchment
  11. Yeah I don’t really know about the energy economy at scale, but if forecasts are consistently a few degrees more accurate, then of course energy companies would prefer those forecasts because over the long run, they are more prepared to efficiently provide energy
  12. Seems like it’s worse at vorticity but better at geopotential heights. Worth noting also that 20% increase in temp forecast accuracy three days out should have sizable implications for the energy industry, no?
  13. From Nature: https://www.nature.com/articles/s41586-024-08252-9#Fig3 “As shown in the scorecard of Fig. 3, the forecasts of GenCast are significantly more skilful (P < 0.05) than that of ENS on 97.2% of our 1,320 variable, lead time and vertical level combinations (and 99.6% of targets at lead times greater than 36 h)“ Seems like a significant improvement on its face, would leave the more technical analysis of the graphic to those more knowledgeable
  14. Right. Instead, we just sit here, look at 360 hr charts, and go like “aw shucks, hopefully it’s wrong” because we (or maybe just me personally) can’t put our finger on the driving causes
  15. I feel the same way, would be awesome to have my finger on the pulse. I’d imagine you’d have to have about 17 data sites saved in a folder that gets checked daily, along with probably a weekly long-term blogging practice. Otherwise, important signals get lost and the whole enterprise isn’t even worth it
  16. In other news, it seems that that Alaskan ridge might regenerate after a mid-month warmup. We also enter phase 7 in late Dec, but we may need to wait a few weeks for any other good chances
  17. There’s a degree of schadenfreude that NYC folks can get when New England snow lovers get disappointed, because they themselves are so used to missing out. Especially during otherwise favorable +NAO patterns. It’s best to just let them troll as they cry in 50 degree average high temps
  18. We were just there over Columbus day - hope you got to chat with the art vendors down the alley there
