Australian Bureau of Meteorology (BoM) own time series graphs web page fails to back up their claims of the “hottest January ever” Australia-wide.March 3rd, 2013 by Warwick Hughes
On page 10 of 23 the BoM “Special Climate Statement 43 – extreme heat in January 2013″ – Updated 1 February 2013 – says –
“2.5 Monthly mean temperatures for January
January 2013 was Australia’s hottest month on record. Averaged nationally, the
maximum temperature was 36.92°C, 2.28°C above the 1961-1990 average, and 0.11°C above the previous record of 36.81°C, set in January 1932. The monthly mean
temperature (day and night combined) also set a record. It was 29.68°C, 1.77°C above the 1961-1990 average and 0.27°C above the previous record of 29.41°C, also set in January 1932.”
Now making graphs for each of the States and Territory at this BoM web page. When you check out what I have done, make sure you set the page to Mean Temperature – choose your State – then pick January.
New South Wales & the ACT – no record January 2013 here
Queensland yes a tiny win for the BoM by 0.1°
Victoria shows no record warm January 2013
Tasmania likewise shows no record January 2013
South Australia likewise shows no record January 2013
The Northern Territory did set a record mean temperature for January 2013
Western Australia set no record mean temperatures for January 2013
What on earth is wrong with BoM data ? According to the web-page these charts use the brand-new-you-beaut-adjusted-warmer ACORN data.
If anybody has an explanation of how an Australia-wide record hot January can be claimed that does not show up in 5 of the 7 State/Territory regions, please let me know.
