Extremely hot summer in Australia has started very soon, despite of expected above average cyclone season and La-nina /https://mkweather.com/2020/10/12/powerful-cyclone-season-in-australia-is-expected-9-15-cyclones-is-forecasted//, which should bring less temperature extremes, than in summer 2019/2020, when Australia was bothered by the strongest wildfires in history.
Already on 13. November 2020 has been in the hottest places of Australia measured new absolute November temperature record – Fitzroy Crossing in northern part of Western Australia reported anomalous +46,5°C / 115.7°F, what is the same value as all-time record for the place for the whole month of November.
This heatwave has occurred in extremely hot air, +31°C in 850 hPa near sunny and calm “desert” weather.
Heatwave is gradually shifting over South Australia, Victoria and New South Wales, with next heatwave in the most populated region in Australia during incoming period.
Thanks to historic strong AAO+ (Antarctic Oscillation, equivalent of Arctic Oscillation for the Southern Hemisphere), cold fronts beside of last powerful front /https://mkweather.com/2020/11/13/adelaide-cooldown-from-385c-to-182c-48-hours-maximum-temperature-after-extreme-powerful-cold-front//, have had during spring 2020 more southward shifted tracks such as an average and during the summer, limited impact of cold fronts to weather in large parts of Australia is expected.
It gives in result of very good conditions for drought and next deadly wildfires, however, from north and northeast, cyclones should stop several heatwaves by humidity and rain, although near high temperatures and high heat index.
Evolution of heatwaves during late spring is however disturbing – soon will be possible temperatures above +50°C in northern and central parts of Australia and it is very close to significant wildfire risk near transition of these extremely hot air masses to the southern regions.
