BOM forecaster Dean Narramore told AAP.

“We saw on Saturday an incredible amount of records broken in NSW and that heat is just moving north for Sunday.”

Four Queensland towns set their highest ever recorded temperatures on Saturday as Brisbane reached 37C.

‘kg007’said”One record equaled today, 6 days straight of 35c plus for December, equals record set in 1898!

and
“Adelaide now has recorded four days in a row of 40c plus, just peaked at 40.4. Breaking record set of 3 days in 1898 and 2007.”
and
“Some new December records set today Clare 41.7, Pt Pirie 44.8, Snowtown 44.9!”
and
“Port Augusta can be added to the list has hit 46.4 previous record 46.1!”
and
“Scratch that, Pt Pirie now 45.4, Snowtown 45.2 more than 1c above previous records!”
and
“Pt Pirie at 45.6, previous record 44.0!
Whyalla hit 45.5, previous record 44.9!”
and
“Port Augusta new record 47.2, previous 46.1!”
and
“Edinburgh has equaled its December record with 43.5c!”
and
“Whyalla has new record of 45.8, previous 44.9!”

KEN KATO
“The all-time record for most number of December consecutive days with 40C or above was broken though.
BLAIR TREWIN
“The most impressive record I’ve seen so far is Snowtown’s, where 45.2 is a December record for old and new sites combined (data back to 1908). The current Port Augusta site is a fair bit hotter than its predecessors but 47.2 is still an impressive number.

Did ENSO and the “Monster” Kelvin Wave Contribute to the Record High Global Surface Temperatures in 2014?

BOB TISDALE investigates the causes of the record warm global temperatures for 2014

He concludes
“If there was any doubt, the ENSO-related warming of the tropical Pacific in 2014 did contribute to the record high global sea surface temperatures, but without the exceptional weather-related warming of the extratropical North Pacific (Figure 12), 2014 would not have been a record warm sea surface year globally (Figure 7).

Of course they did.

Those who have followed the 2014/15 El Niño series from its start back in April will recall all the hoopla about the strong downwelling Kelvin wave that was traveling from west to east along the Cromwell Current (aka the Pacific Equatorial Undercurrent).  Based on the size of that Kelvin wave, alarmists were anticipating a super El Niño that would cause record-high global surface temperatures, but the super El Niño failed to form.

The strong Kelvin wave earlier this year took a massive volume of warm water that had been below the surface of the West Pacific Warm Pool, where it was not included in the surface temperature record, and allowed that warm water to be spread across the surface of the tropical Pacific, where it was then included in the surface temperature record.   The surfaces of the tropical Pacific had to warm in response. They could…

KEN KATO says
“Check out all the locations from Laurier’s AWN site where records for hottest temps were equalled or broken in the past few days:

It’s worth noting many of these sites also broke their records on other days this month as well, some on consecutive days.

Many other locations in SE QLD broke all time records again yesterday. Just some of these include:

St George – 41.7 (record was 41.2 set in 2002)
Gatton – 41.6 (record was 40.6 set in 1988)
Amberley – 41.3 (record was 41.1… open since 1941)
Oakey – 39.1 (record was 38.3 set in 2002)
Warwick – 38.5 (record was 37.1 set in 2002

Toowoomba – 36.4 (record was 36.2, records go back to 1869)
Stanthorpe – 35.5 (record was 33.4 set in 1988, open since 1873)

Applethorpe – 33.6 (record was 33.0 set in 2002).

Special Climate Statement 49 – an exceptionally prolonged autumn warm spell over much of Australia

8th -26th may 2014

Extract
“An exceptionally prolonged warm spell affected large parts of Australia during May 2014. The unusual warmth was concentrated in the southeast of the continent, with areas affected including Adelaide, Melbourne, Sydney, Brisbane, Canberra and Hobart.

—–
“2.2 Long spells of consecutive warm days and nights

The length of the warm spell was its most significant feature in a historical context. Forty of the 112 ACORN-SAT (long-term temperature reference) stations in Australia, including most of those in Victoria, South Australia and New South Wales, set records

————-
“. Twenty-five of the 112 ACORN-SAT locations set records for high late-season maximum temperatures. At some locations, particularly in New South Wales and the Australian Capital Territory, the temperatures observed on 26 May occurred at least two weeks later than any previous occurrences of such values. 24.1 °C was observed at Campania on 15 May, the highest maximum temperature so late in the season for any Tasmania site. This was followed by a similar record for Victoria, with 27.4 °C at Ouyen on 26 May. Also on 26 May, Birdsville reached 34.7 °C,

EXTRACTS

Some sites in the pastoral districts had no rainfall for the month and hence their equal lowest total January rainfall on record.

Many sites had record hottest days, and record runs of very hot days.

record hottest January daytime temperatures at locations on the Yorke Peninsula and across the southeast of the State.

during 12th to 18th due to northerly winds around a high pressure system centred over the Tasman Sea. Maximum temperatures were in excess of 10 °C above average across most of the agricultural parts of the State through that period.

Coober Pedy, Tarcoola, Elliston, Neptune Island, Stenhouse Bay, Cape Willoughby, Mount Lofty, Keith, Mount Gambier and Naracoorte all had hottest days on record for any month, these new records mainly occurred under heatwave conditions between the 14th or 16th of the month.

Many sites also had record runs of very hot days, including Adelaide, Renmark and Roseworthy recording 5 consecutive days of 42 °C or more, Port Augusta recorded 5 days of 45 °C or more

On the 5th Mount Lofty recorded the coldest day for any location when its maximum temperature reached 14.1 °C. Despite the widespread heat across the State at the beginning of January, Keith in the lower southeast district observed its coldest January day (lowest maximum temperature) on record on the 2nd.

Cleve had a record run of 2 nights in a row with minimum temperatures of 30 °C or more, while several sites had record runs of night where minimum temperatures were 25 °C or more, including 4 consecutive such nights at Maitland and Strathalbyn.

An intense heatwave in central and eastern Australia.. BOM climate statement no 47 Issued 6 January 2014

The BOM have issued a special climate statement for an extreme heat anomaly for parts of Australia

    EXTRACTS from
    Climate statement 47
    .quote” For the week ending 4 January, average maximum temperatures were 8°C or more above normal over parts of southern inland Queensland, and were at least 6°C above normal over most inland regions of that State, as well as parts of northern inland New South Wales. Inland Queensland has been seriously affected by drought over the last 12 months and it is possible that low soil moisture was a contributor to the intensity of the heat.

    The highest temperature to occur during the heatwave was 49.3°C at Moomba, in the far northeast of South Australia, on 2 January. (It was marginally hotter, 49.6°C, at the same location in January 2013).

    12 locations in northern South Australia, southwest Queensland and northwest New South Wales reached 48°C or above (Table 3). This included a site record 49.1°C at Walgett on 3 January, which was also the highest temperature observed at any New South Wales location since 1939 (when it reached 50.0°C at Wilcannia and 49.7°C at Menindee during the heatwave associated with Black Friday).

    45°C was exceeded over most of the central and eastern interior of Australia, as well as over the Nullarbor (Figure 2).

    The most significant records broken were on 3 January. It was the hottest day on record for Queensland, in area-averaged terms, for daily maximum, minimum and mean temperature (Table 4), with the statewide mean temperature exceeding the previous record by an extraordinary 0.75°C.
    The day was the hottest on record over 10.2 per cent of Queensland and 14.6 per cent of New South Wales (Figure 3), a region covering most of the Maranoa and Warrego in Queensland, and the Northwest Slopes and Plains and Northern Tablelands in New South Wales. In total, record high maximum temperatures occurred over 8.8 per cent of Australia from 1 to 4 January, including 16.8 per cent of New South Wales, 16.8 per cent of the Northern Territory, 15.2 per cent of Queensland and 7.9 per cent of South Australia.
