Volcanic Winter Posted November 30, 2022 Share Posted November 30, 2022 21 hours ago, Dark Star said: If there is a major volcanic event in the northern hemisphere, what is the general lag time to affect the weather globally (or is this a ridiculous question)? The sulphur infiltrates the stratosphere and spreads into the stratospheric aerosol veil fairly quickly. I can link you some information on this, will edit this comment. It takes a couple years for it to precipitate out and thus end the effect, but the impact can be IIRC within a few months. It really takes a large eruption though. HTHH was just about the right size but was very gas poor for several reasons (except water vapor which is different of course). Edit: Anyone interested, read these articles and pay attention to the included charts. Explains the process rather well. https://www.volcanocafe.org/ruminarian-v-get-your-coffee-youre-gonna-need-it-repost/ 1 Link to comment Share on other sites More sharing options...
Volcanic Winter Posted November 30, 2022 Share Posted November 30, 2022 53 minutes ago, Dark Star said: Supposedly another volcano in Russia is a possibility as well. I think it takes about 6-12 months before the effects on the weather (if any) begin to take place? Shiveluch has had several large eruptions in recent history, but I’m not sure it’s currently at risk of anything massive enough right now to have a major climate impact. I’m going to dive deeper into the unrest that’s prompting the influx of articles about it, because nothing a short while ago was really pointing to it having anything more than a continuation of normal activity levels. I could be wrong but will investigate further. With that said, a low end VEI 5 like St Helens or Bezymianny won’t cut it. You need a particularly gassy El Chichón style VEI 5 which doesn’t encompass every volcano that erupts that large, or more probably a ‘near VEI 6’ (8-9km^3 erupted volume) to Pinatubo level and above. Pinatubo was even relatively small for the strength of its volcanic cooling episode, but it was exceptionally gas laden and deposited something like 20MT of sulfur into the stratosphere (El Chichón was much smaller and released 7MT). Pinatubo also had a boost from another large mid level VEI 5 eruption at Cerro Hudson in 1991. It’s part size of the blast, part composition of the magma and expelled gasses. In general the bigger the event the more likely it is to impact the climate. Hunga Tonga only did about 1/40th the sulphur release of Pinatubo, and it was nearly as large (some publications actually have it as larger, interestingly enough). With respect to HTHH I’m much more interested in how the combined loading of a decent shot of volcanic ash and a large injection of water vapor influence the upper level dynamics. That article speaking about the intense stratospheric cooling observed in the SH after HTHH was very interesting. It showed correlative evidence that such cooling events in the SH (however not from volcanic events in other cases, might be a big point here) correlated to stratospheric warming in the NH and -NAO states. HTHH was a very interesting event and I’m curious to read some retrospective climatological analyses in a few years. It may have a hand in some things going on right now, or maybe not. Back to Kamchatka, you really need something incredibly massive to have a major volcanic winter. Something like the Kurile Lake eruption: https://en.m.wikipedia.org/wiki/Kurile_Lake This was similar to Tambora in 1815 (though likely a bit larger) which caused the major anomaly in 1816. Not to mention, the 1810’s were one of the coldest decades ever, partly influenced by another massive VEI 6+ eruption of unknown origin in 1808/9. And yes, two eruptions of that magnitude only a few short years apart is exceedingly improbable; but the ice cores don’t lie! 1 Link to comment Share on other sites More sharing options...
Volcanic Winter Posted December 1, 2022 Share Posted December 1, 2022 So it looks like Shiveluch is extruding a lava dome (think of it as a swelling bulge of hot but cooling / crusting magma that plugs up the crater), which as they swell are prone to collapse and explosive / pyroclastic events. This is similar to La Soufriere in 2020-2021 that extruded a massive lava dome that ultimately triggered a moderately large sub plinian to plinian eruption. VEI 4, a decent and visually spectacular event no doubt, but too small for climate impacts. Shiveluch just had a partial dome collapse that sent a pyroclastic flow 10KM away from the edifice. Pretty impressive but not directed upward to the stratosphere. I would imagine intermittent sub plinian blasts and dome collapse pyroclastic flows (lateral not skyward) would be the main threat here. But if the dome grows massive or something more destabilizes in the volcano, for sure we could get a bigger event. Link to comment Share on other sites More sharing options...
TWCCraig Posted December 1, 2022 Share Posted December 1, 2022 A sad day for what is a great website for GOES satellite data. Doesn't affect our area but it was cool being able to see the entire western hemisphere (both north & south). Bandwidth issues... any other great satellite websites out there?

While frugality has its place, I think enjoying some basics (like yaknow, heat) with your hard earned money is pretty reasonable. Mine’s on usually around 45. Thermostat usually in the mid 60’s until January ish, but our bedroom usually runs below thermostat temp. We have a nice down blanket in bed and snuggling for warmth is more fun anyway. 1 Link to comment Share on other sites More sharing options...

BlizzLuv Posted December 4, 2022 Share Posted December 4, 2022 Geez my "goal' is to keep the heat off until Halloween and the A/C off until Memorial Day. My wife usually derails the Halloween goal but we get close. I usually sabotage the Memorial Day goal myself. The older I get, the less tolerant I am of the outer boundaries - inside and outside. Though, I still enjoy snow and cold now through the end of January. 1 Link to comment Share on other sites More sharing options...

Had to vent some general disappointment but I’m ready to rock the end of this month. I want to be outside in my boxers making snow angels on my front lawn by Xmas.
