News from climate skeptics in New Zealand

When New Zealand weather does not behave as IPCC compliant organizations forecast it is referred to as “mad”

A classic from the Fairfax GreenLeft NZ Herald – From heatwave to violent storms: New Zealand’s mad weather – Mad is code for, the NIWA forecasts of hot dry weather caused by El Nino are being shot down but Herald readers are supposed to understand that crazy or in this case mad weather can be caused by “climate change” too.
Amazing that the article does not refer to remnants of Cyclone Ula which is nearing the East Cape region as an ex tropical low pressure system. Map source.

It is not unusual for the remains of cyclones to vent on northern NZ in summer.

Worthwhile New Zealand rain reported as “a drop in bucket”

Another fascinating example of the baleful influence of climate change dogmas and useless Govt forecasting on normal media reporting standards.
By all accounts the rain was useful in many areas to freshen up grass and give feed growth a summer boost. A subtext is that the NIWA three month Outlooks predict dryer than normal conditions due El Nino – so rain sort of goes against that meme. I like the oracle quoted to explain how it rained because air moved from east to west.
I see another article – Urgent need to act on our water supplyWhaleoil is on to it. It seems anti-dam dogmas are rife in NZ and all manner of special interest groups get into the act to make a needed new dam even more impossible. When will water users start voting for an adequate water supply at an affordable price?

New Zealand hottest ever day in February 1973 arrived directly from Australian heatwave

After being pointed to a NIWA page of NZ climate extremes I saw that the hottest ever day in NZ was the 7th Feb 1973 when it was 39.2 at Ruatoria and 42.4 at Rangiora. Curiosity made me check Sydney that month and a ~40 degree heatwave ended on the 6th. Contour map of the Australian max temp anomaly 6 Feb 1973.
Fascinating that the Australian air traveled ~2400 km over the ditch yet retained heat to make 40 across Aotearoa. Yet pro-IPCC dogmas would not admit to UHI warmed air wafting out to the countryside to affect rural stations.
The BoM rates Canberra Airport as a “non-urban” site despite close proximity to booming urban area.

New peer reviewed paper finds that New Zealand warms at only 0.28°C per century compared to Govt NIWA trend of 0.91.

Good to see this new paper – A Reanalysis of Long-Term Surface Air Temperature Trends in New Zealand – by C. R. de Freitas & M. O. Dedekind & B. E. Brill.
Also great to see them use the Fig 3 twin diagram ex NASA GISS – that I have been drawing attention to for years as absolutely vital.
Climate Conversation Group has a blog yesterday – Paper adds interesting perspective on NZ temperature trend

NIWA reports on record New Zealand warmth for June 2014

This article from Stuff reporting NIWA-talk mentions “A persistent lack of southerlies had a profound impact on the monthly temperatures.”
Or you could say northerly winds brought a flow of warm tropical air over the New Zealand region during June – as shown by this BoM map.

The NZ Herald says – The winter of our content: Warmest-ever June – which mentions June was between 1.8C and 1.9C above normal just beating 2003 which was +1.8C – When global datsets update we can check what they record for June. The NIWA NZ series is heavily adjusted to a warmer trend – explained by Bob Dedekind.

New Zealand climate gurus NIWA hacked from IP address in China

Hackers must be bored and hard up for something to do – Hack attack on Niwa from China IP address – What could be of interest to hackers there? – except the cheap thrill of being inside where they should not be.
On the other hand –
In February 2011 I lodged an FOI request with the BoM to release to me all documents and data connected with their work on the seven station series for NIWA. Included in the reasons for refusal was – “..disclosure would or could reasonably be expected to cause damage to the international relations of
the Commonwealth.”
NZ weather data is powerful big-secret.
Maybe the NIWA supercomputer is a portal to Western World secrets.

So not all New Zealand will enjoy “perfect summer” by mid January as cold front hits NZ like a freight train

A few weeks ago I was hearing from Kiwis that summer was slow arriving – I noticed this optimistic story in NZ Herald on 1 Jan 2014 – Perfect summer days likely to follow patchy spell, analysts say. I took a copy to checkout around middle of month. Today I see – Cold front hitting NZ ‘like a freight train’– Brendan Manning – 16 Jan, 2014
Does this mean the perfect summer arrived and now is departing?
Or did the perfect summer not really arrive at all?
Always interested what is happening over the ditch.
I remember as a kid in 40’s n 50’s that my parents knew to holiday late in the NZ summer when weather was more stable.
This set of animated weather forecast maps by USA based WeatherStreet.com suggests that after the weekend the remains of the front could join with a tropical cyclone heading for NZ from direction New Caledonia. Possibility of more weather.

Rainfall history to help see the New Zealand drought in perspective

The BBC is reporting – New Zealand North Island hit by worst drought in 30 years. Curious to see some rainfall graphs I turned to KNMI Climate Explorer but it was not easy getting updated data. The GHCN V2 data assembled by NCDC in the USA has many data gaps post 2004 and ends anyway in March 2011 – see picture below. The CRU data ends at 2009. I wonder why – it still rains here and there – did somebody stop paying their salaries ?
So I turned to a shorter term partly satellite based data set from GPCP to bring the graph up to date at Dec 2012. The GPCP might reflect rain over both land and ocean – but that is what we have.

Note the grid area chosen misses out Southland and much of Otago west of 170°East. New Zealand should have rain data from say the 1860’s – if anybody has up to date station data please let me know – or please pass on URL’s to any published New Zealand rain history graphs.
This is a common feature when researching climate data – to find that recent data are worse than old data.

Perfect from 1900 to 2004 – then gaps abound.

Speculation that parts of New Zealand could hit 40°C in next few days

The NZ Herald quotes long time climate expert Dr Jim Salinger in their article today – Heatwave: Scientist tips a scorcher – Another bio for Dr Jim Salinger.
Further down the article NZ MetService and WeatherWatch people say that 40 degrees looks unlikely. I hope some Kiwis can send in temperatures from – “…east of the South Island and southern North Island…”. Here is a site where you can type in a NZ locality and get weather data.
Is this a case of Fairfax media believing some of the over-hyped rubbish about heatwaves in Australia and thinking that it had to be the turn of NZ sometime.
