The Australian Bureau of Meteorology needs to be questioned about their temperature adjustments – under conditions such as at a Royal Commission or at Senate Estimates

The latest article by Ken Stewart – Rutherglen: Spot the Outlier – builds on the momentum started by Dr Jennifer Marohasy who was a key to articles in The Australian on 23-24 August which questioned the BoM ACORN SAT high warming adjusted temperature series. And of course Jo Nova has been active on this issue [...]

It is time to get Australian Bureau of Meteorology station histories out of archives – we need to see how good BoM metadata is

The best reference I know to BoM station diaries is the 45 page summary by Simon Torok for his 1996 PhD thesis – “The development of a high quality historical temperature data base for Australia” This can be downloaded in full in several parts at – minerva-access.unimelb.edu.au/handle/11343/39449

However the Appendix A1 containing the 45 page [...]

Renmark Aero has coldest ever 7 day run of August minimum temperatures – that is in eastern South Australia

Checking Renmark Aero minimums for 7 days 2 August to 8 August 2014 and they average -3.97°C. Renmark has two stations with daily max & min T available – 24016 Renmark with data from 1957 to 2001 which had no seven day spell in August even breaking zero. Then Renmark Aero 24048 with data from [...]

Canberra Airport has coldest ever 14 day run of August minimum temperatures

Checking Canberra Airport minimums for 14 days 2 August to 15 August 2014 and they average -4.55°C. I think this is a record cold run of 14 cold minimums in August – since 1939 that is. The next coldest 14 day spell I found was -4.25°C from 4th to 17th August 1994. Has anybody noticed [...]

3rd August 2014 saw record cold mornings in Hay, Hillston and Lake Victoria – in New South Wales that is

While roughing it in a motel in the wilds of central NSW I heard the ABC weather lady say that Adelaide was enjoying a record cold August morning – a record since 1888 I think. Yesterday was a pretty hard frost here so I have quickly checked a few records and it looks to me [...]

NOAA claim that May and June 2014 were hottest evah for our globe

The Ch9 TV weather lady for Sydney mentioned this last night – and I see this article in USAToday – A double scorcher: June joins May with heat record – Of course NOAA is quoting weather station data assembled by the GHCN latest effort where most sites are in urban heat islands and then they [...]

How long does it take the Australian BoM to fix a simple 10°C error in their AWAP temperature anomaly maps?

On the 5th I posted – Southwest Queensland heat wave 2 July 2014 – pointing out the 10 degree error for the Bedourie max on 2 July. After a couple more days the 30 was fixed to a 20 here. But I see this morning 14th July after another week passes – that the 10 [...]

Global warming strikes Queensland – Brisbane has coldest morning in 103 years

Brisbane records coldest morning in 103 years – despite the ever growing urban heat island – records falling in several other towns. I am sure sure there will be more to say about this – too busy now.

Southwest Queensland heat wave 2nd July 2014

I noticed this aberration in BoM max anomaly maps – on checking I see that Bedourie on 2 July recorded 19° at 3pm. Yet they have 30° recorded here. So we are expected to believe that the temperature rocketed 11 degrees quicktime It just amazes me that such an obvious outlier can get through BoM [...]

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 [...]
