    I have always wondered why 81 was such a big season . There is an interesting program on sbs tonight about the effect of volcanoes on Egypt and the biblical Moses related events . We know about pinitubos effect on global weather and sulphur dioxides role in 91 and 92 and the oz snow seasons . Did my St. Helens have this effect too , specifically the 81 oz snow season ? Your thoughts ?

    '81 started early and finished late. 2 weeks after the October long weekend I was riding the Eyre lift. A little surprising. But in places the T-bar track was in a trench over head high. I have never seen anything like it, before or since.

    As regards volcanic causes, Mt St. Helens was relatively small compared to Mt Pinatubo. And Pinatubo ejected gases up to 50km up into the high stratosphere, with around 15M tonnes of SO2, which creates aerosols that block sunlight. Because it was so high, it spread around the world, and persisted for a couple of years.

    St Helens eruption had very little SO2, with mostly ash, which reached lower levels of the stratosphere. There was almost no lasting effect.

    As for what caused the great season of 1981, it's very difficult to say.

    However, some time ago, I noticed that 1981 was quite unique so far as SOI is concerned.
    1981 had low negative SOI from Feb/April, swinging to high positive values May->September.
    More specifically, the averaged SOI from Feb-Apr swinging from -8.4, to May-Aug to +8.6
    The only slightly similar year since 1954, was 1990 that swung from -8.8 to +3.7, and that one was BIG.
    So the swing is positive.

    OTOH, some very bad seasons swung the other way:
    2006: +9.4 to -9.4
    1982: -0.3 to -17.8

    And some have swung negative, but were good seasons. However, they swung from high +ve values to around neutral:
    2000: 13.0 to -0.1
    2008: 12.7 to +3.0

    There may be some correlation in the swing rather than the absolute values of SOI, or it might be coincidence. ;)

    I don't know what caused it , but '81 was insane . It started to piss down raining the night before the last day and it flooded the restaurant of The Chalet , then about 10 am it turned to snow and puking , we were skiing knee deep pow before we had to go back and rip up the carpet for the end of season party .

    Huuuge year, although had a warm rain period near end of july , and got warm in sept so other years may have had a better mix of depth , weather and longevity , but heres a couple of anecdotals.
    1. Donna Buang had a depth over 1m at one stage.
    2. Major driftage at hotham as a combination of both wind and snow amounts , particulary through august and early july.
    Many cases of buried cars ( quickly ) multiple instances of cars parking on top of cars ( didnt know they were there) , lodges buried.
    3. Skied top to bottom down tyrol at buller with at least 1.5 m cover down the bottom of village , cow camp.
    4. Brockhoff poma buried for a period of time and severe trench action to keep it running .

    I've been trying to find some pics from 1981, but apparently my Google foo is failing me.

    Anyone else have luck?

    First year I ever stayed on snow at Threddy as a 10 years old. For years after that i wondered what was going on with the snow and just assumed we must have been there too early or too late.

    I just always assumed it was due to Mt St Helens. Can't remember why. Someone must have told me that at some point.

    This sounds a lot like something I noticed in regards to teleconnections some time ago as well. I lost interest in trying to identify it further after a while. I think Gerg tried to help me for a bit.

    I will never forget 81 till my dying day. Neither will I forget 82. A lesson in contrasts.

    I'm getting to old, 1964 was my big year. When you compare the two they were similar. In 81 I was in N.Z. but up the top of the Nth. Island and didn't even see snow.

    What I remember most of 1981 was the epic cold outbreak of late June - A nice cover of snow over North Central Vic down to 250m ASL on the 23rd. The hat-trick of 90,91,92 were also 3m seasons but 2000 was the season I skied in May and October...

    In '82 there wasn't enough snow to run the lifts so we used to take guests for walks to Kosci for a picnic lunch , or I would walk out to Carrutthers with guests and ski back along the ridge line . There was a lot of walking in '82 .

    A lot of shoveling in 81, the year I work at Buller on lifts, constant de-icing, huge rhime build ups.

    The average pressure winter 1981. Note the sub tropical ridge is sitting well north. I would say 1981 was a result of negative SAM.
