  1. Me too...living inside 128 with all the cars and trucks blackening the snow 10 minutes after it falls...at that point I would rather put it out of its misery.
  2. I believe it was the relatively large amount of sulfur dioxide released by Pinatubo, which when it crystallizes in the upper atmosphere is light-colored and reflects back a lot of the sunlight. Hunga Tonga had a relatively ow proportion of SO2 in its plume, which is why it's probably NBD in its effects on climate.
  3. Even in the lackluster '80s, weren't the Januarys of '86 and '87 both prolific (BOS around 24" both years)? Those helped mitigate the general ratter-ness going on then
  4. FWIW, this eruption released less ash and SO2 than even St. Helens in 1980, let alone Pinatubo in 1991. Its effect on the climate is probably far less that we saw in 1992 with Pinatubo. Also, volcanoes that erupt in the tropics (e.g. Tonga) tend to result in +NAOs and warming, at least for the first 9 months or so, before any cooling sets in. That said, I'm not sure what difference a winter-erupting volcano would make, as opposed to the summer eruption of Pinatubo, whose cooling was not apparent here until the following March.
  5. Winter’s back will break, according to Old Farmer’s Almanac (on Feb. 18) of course, that requires winter to actually HAVE a backbone in the first place…
  6. Yeah, about 9 months of +AO resulted from that. IIRC, Then it flipped suddenly in March of 1992. BOS actually got more snow that season AFTER the vernal equinox than before. Then we hit the bonanza winters of 92-93, 93-94 and 95-96. two things, though: Pinatubo was a much larger eruption than this one in terms of plume altitude and volume ejected (unless we get subsequent eruptions) and I’m not sure if even a larger eruption would be enough to flip the ENSO state.
  7. Ash and SO2 eventually have a net cooling effect, but it’s a tropical volcano, which tends to give us 9-12 months of +NAO at the beginning. Also don’t know how much particulates have been ejected. Will also depend on any future eruptions, obviously.
  8. There goes the futility title for this year. (1936-37 BOS)
  9. The issue here is the SE ridge and all the velocity it's creating as the flow tries to bump up against it and gets compressed. We've seen it so many times, it's endemic in this fast-flow environment, especially in a Nina. It can't dig enough.
  10. Snow crystals slamming against each other is the leading theory of how thunderstorms get electrified.
  11. Yup - shift everything 200 nmi east and we’re good. Also would help to have a 50/50 low to lock in cold air. But maybe that doesn’t normally show up yet anyway. Any correlations that anyone has noticed between 50/50 lows and ENSO state? .
  12. Hingham also has a orientation issue - it’s on an east-west oriented stretch with water to the north. So even a NNE or N wind, which would give most everybody else a shot at holding on to some cold, has too much overwater fetch to make it work. Granted, it’s mainly just Boston Harbor we’re talking about, but especially early in the season, it mixed in too much heat content at lower levels. .
  13. The time of year too - this time of year the sun is always below the maximum 42 degrees elevation, so the rainbow is visible all day. The farther away from noon it is, the more rainbow is visible. .
  14. We're still temporally near the minimum of the cycle even though getting some active sunspots. I think we're still good even with the recent spike given the historically low background state of this cycle. Also, the low but ascending part of the cycle generally seems to do better than the descending part anyways (unless you're near the 11-year peak)
  15. Simple momentum transfer from the falling rain would make one think so.
