Storm facts

June 22nd, 2013 at 7:40 am by David Farrar

report:

  • NIWA has been measuring wave height from a buoy two kilometres off Baring Head, Wellington, since 1995. Last night’s waves are the largest seen in that record.
  • Last night, the highest waves measured were typically 15 metres, from peak to trough, for the period around midnight last night.
  • Anecdotal information records the wave height at the time of the Wahine disaster at 12 to 14 metres.

Now I understand how the wall at Island Bay was destroyed.

  • These measurement show that last night’s storm is in the same category as five other major storms recorded in 1961, 1965, 1967, 1974, 1977 and 1985.
  • The maximum 10 minute average, sustained wind reading during the Wahine disaster was measured at 144 km/hour and stand out by far as the strongest in the 50 years of the record.
  • So this was an extreme event, but still not as intense as the Wahine storm.

But not as windy as Wahine.

  • The largest snow storm on record in the central South Island was registered in 1973.
  • Snow depth recorded by NIWA staff at Methven yesterday was 99mm compared with 610mm snow depth measured in 1973.
  • At Lake Tekapo, the snow depth of 600mm measured yesterday was similar to the 670mm measured in 1973.
  • The snow depth recorded on the inland road near Waiau yesterday was 229mm, slightly more than the 161mm recorded last year.

And still some way to goon the snow front.

    No need. The scientists have confirmed there is nothing historic or exceptional about the measurements and there has been more snow and bigger waves decades ago.

    I remember when the ice burg floated off the coast of Dunedin there was some alarmist “scientist” on the telly excitedly telling us it was global warming causing it and in the same breath referring to another ice burg that came even closer when the area was first settled, back in the sailing boat days !

    Sorry but snow and freezing is called winter, not warming.

    Something has just clicked into place in my mind. The storm left over 30,000 people without power, which implies that most 11,000 volt overhead feeder lines (which feed transformers serving 100 or so households each) must have suffered some sort of damage. By contrast AFAIK few in Wellington City (excluding Johnsonville, Makara and Ohariu Valley) would have lost power. The 1985 storm had similar consequences. In the late 1980′s some elected members of the former Hutt Valley Energy Board convinced the Board to adopt an undergrounding programme, and it seems to me now this would have been influenced by the effects of the 1985 storm. A programme was grudgingly adopted by management , and gained further acceptance following changes due to retirements, etc. This involved spending $1M the first year increasing in $0.5M increments until the programme was complete (a decade or so). The Government in the early 1990′s effectively sacked elected power boards and imposed boards of directors instead. These directors agreed to the continuance of the programme, but at $1.5M a year. The programme was canned in 1997 or so following further major changes. Priority was given to areas of high amenity value meaning that areas such as Petone Esplanade, much of High St Lower Hutt, much of Fergusson Drive, Upper Hutt, Mana Esplanade, main roads through Porirua East/ Waitangarua and other areas were completed. Much of the road to Eastbourne had been completed, but pockets remain that were not done.

    The programme, if completed, would have avoided most of these 30,000 people losing power on Thursady and reduced much misery. Granted, the programme would have resulted in another cent or so on power bills, and in a strict sense would not have been ‘economic’ (ie the benefits less than the cost). It possibly comes down to – would people be prepared to pay an extra $80 – $100 per year as ‘insurance’ against power failures during storm conditions.

    The current regulatory framework is against any such underground programmes. They would be regarded as ‘gold plating’ by the regulatory agencies and lines companies risk not being permitted to make a reasonable return on any undergrounding investment.

    For many years now councils across the country have been stopping folk using fires for warmth. Fires can also be used for boiling water/cooking.The authorities seem to think that electrictiy supply is dependable when it’s not.

    Time to be encouraging wood and coal burners so people can be warm and independant.

    Kowtow. Couldn’t agree more. Our wood burner was literally a lifesaver during the 2011 snowstorm with power out to our rural Wellington valley for over 48 hours.

    That storm led to our investment in micro hydro. At the time I calculated the NPV payback from the investment as 10 years assuming no disruptions or adverse weather events. A shade under 2 years later we’ve broken even.

    My day job involves assessing infrastructure projects and the ex ante valuation of network resilience in making investment decisions is far and away the most undervalued component.

    The best place in the country in these southerly storms is the West Coast, those alps do a marvelous job of mounding up snow on the eastern side!

    Twaz a beautiful day yesterday, and for some bizarre reason the forecast gale force winds never really eventuated, does anyone here understand how that was possible? the weather map made it look like a certainty. Obviously some phenomenon to do with pressure gradients or some such kept the wind at a higher level.

    I completely agree. Wood burners in particular are also environmentally sustainable and represent a very efficient way to manage energy demands for heating the family home.

    If you install wetbacks for water heating the advantage is even greater, we have had the power turned off to the hot water cylinder for 10 years now, that equates to more than 10 grand saved in power bills over that time.

    Yet “Consumer” attacked using them ffs!!

    Storm ‘twice in a lifetime event’

    Dr Renwick said the polar blast has been caused by fluctuations in wind currents around Antarctica and a similar event is unlikely to occur again for several decades.

    He said climate change means powerful storms would become more common in future, but even in 100 years’ time this week’s weather would be considered particularly bad.

    a wet back is no use if your h/w cylinder it too far away and don’t (perhaps) have open plan.

    10 grand hj, that’s $10,000.00, “ten thousand dollars” 10 large, 10 gs.

    I can think of 10 000 reasons to move the cylinder closer ;)

    A fire will push hot water 5m or more anyway.

    Some kiwis are 100% passionate about their tree burners…. and just a bit scary….

    Reminiscent of NRA members…. you can take my woodburner from my dead cold calloused splintered charcoaled real bloke mitts.

    Obviously good in places where there’s more of a threat of losing power for days on end like some of the isolated South Island towns in winter. Main centres? Mmmmm…. not so much.

    how typical

    after all you done 6form
    Just for your personal amusement
    snow is frozen rain lots of snow does not equal extreme cold.

    Griff, even if the world was getting warmer, it does not prove man is driving that change. Climate changes with the yearly seasons, but also in a bigger cycle. That is why we see evidence of numerous ice ages followed by [gasp!] warming. It is all perfectly normal and nothing to worry about.

    The day we no longer need BIG OIL is a long long way off. In the mean time you can thank BIG OIL for giving you so much and raising the standard of living of billions of people beyond measure. Or you can stop being a hypocrite and scamper naked into the bush to “live the dream” you spend so much time recommending to others.
