It’s time for another update on the antics of our favourite climate cranks — and this week’s star is New Zealand’s very own über crank, weather astrologer Ken Ring. He’s been reinventing NZ’s warmest-ever winter to make it fit with his forecasts. Here’s Ken, back in April, in a piece headlined “Severe winter ahead” [WebCite1]: […] … Read More

NIWA’s Citizen Snow Project: How deep is the snow at your place? - Waiology

Waiology Jun 20, 2013

By Daniel Collins With the current storm crossing the country this week, NIWA has kicked off its Citizen Snow Project. The project seeks assistance from public at large to contribute to New Zealand’s snow science research by gathering snow measurements at home, in their neighbourhood, or wherever they may be. Snow measurements at NIWA’s Tekapo field office, … Read More

Cold wind to Valhalla: Arctic ice loss brings spring snow to UK and Europe - Hot Topic

Gareth Renowden Apr 01, 2013

It’s been a cold and snowy end to winter in Britain and much of Europe. The worst March snowfall for 30 years (according to The Telegraph) caused significant disruption to much of the UK, and lead to heavy loss of sheep and lambs in Wales.

Map: Projected effects of climate change on New Zealand freshwaters - Waiology

Waiology Nov 27, 2012

By Daniel Collins Maps are helpful tools in communicating and understanding the potential implications of climate change. We have national maps of projected changes in temperature that show faster warming in the north, and in precipitation that show more rain in the south and west and less in the north and east. We also have national maps of … Read More

In high pressure systems, dry descending air suppresses cloud formation, in this [...] … Read More

Citizen science: How deep is the snow at your place? - Waiology

Waiology Jun 06, 2012

By Daniel Collins and Ross Woods Measurements of snowfall at low elevations around New Zealand are few and far between, and yet the data would be really helpful in understanding how snowfall occurs and quantifying snow-related risks. After all, the large majority of New Zealand’s population and infrastructure reside closer to the coast than the mountains. And so we’d like … Read More

Barry Fahey (Landcare Research) et al. use their water balance model, WATYIELD, to assess whether tussock in Otago’s uplands can really intercept … Read More

Measuring snow and rain with a crashed spaceship - Waiology

Waiology Oct 25, 2011

Guest post by Dr Tim Kerr (post-doctoral fellow funded by the Ministry of Science and Innovation, and hosted by NIWA) Back in June, Daniel described New Zealand’s rain as coming mainly from the plains mountains. In the South Island, that generally means the Southern Alps. One of science’s tasks is to refine our understanding of where, why and … Read More
