Hotter and drier- Australia’s weather records set to be broken this year

Australia’s annual heat records may melt after hot and dry October, The Age,  Peter Hannam, November 1, 2019  Almost the whole Australian mainland is likely to have a warmer and drier than normal final two months of the year, boosting the odds that 2019 will be the country’s hottest on record.

Nationally, maximum temperatures last month were almost 3 degrees above the 1961-90 average used by the Bureau of Meteorology, making it the second hottest October in records going back to 1910.

For the first 10 months of the year, average daytime temperatures are running at 1.88 degrees warmer than the 1961-90 yardstick, placing 2019 well on track to smash Australia’s record anomaly of 1.59 degrees set in 2013, the bureau said. Mean readings are in line with the record, also set in 2013.

October capped another dismal month for rainfall, with an average of 8.3 millimetres – or about a third of the monthly average. That made it Australia’s equal-fifth driest October.

Most of the nation shared the relatively hot and dry conditions. In NSW, for instance, it was the state’s fourth-hottest October – with daytime readings 3.3 degrees warmer than average – and its fifth driest with just a quarter of the usual rain.

So far in 2019, NSW is running at the hottest for any similar period for both mean and maximum temperatures, while having among the five driest January-October periods on record……

The bureau’s latest three-monthly outlook offers little relief for most of the country.

“November and December rainfall is likely to be below average across most of the country,” it said, adding that the relatively dry conditions were likely to extend through to the end of summer for most of eastern Australia.

For November to January, the odds are running at more than 80 per cent for warmer than average days for the Australian mainland…….
