Australia Braces for Extreme Weather: From Cold Fronts to Heatwaves
Australia is bracing for extreme weather conditions caused by a rare atmospheric phenomenon. The Southern Annular Mode (SAM) has turned negative due to sudden warming in the stratosphere over Antarctica, leading to contrasting weather patterns across the country.
In the south, regions like Tasmania and southern Victoria can expect increased precipitation and cooler temperatures. This is due to the northward shift of the belt of westerly winds, bringing cold fronts and low pressure. A cold front is already set to bring thunderstorms and damaging winds to Victoria on Tuesday, with severe weather warnings in place.
Meanwhile, northern and eastern Australia will experience drier and warmer weather due to high pressure systems further north. Temperatures are set to soar into the 30s and 40s in areas like Western Australia's Kimberley and Pilbara regions, and parts of the Northern Territory. Sydneysiders can also look forward to a week of sunshine with temperatures in the 30s over the long weekend.
Contrasting this, southern states face heavy rain, damaging winds, and flash flooding. Brisbane will see a brief heatwave with a top of 35C on Thursday before temperatures drop. Meanwhile, Melbourne and Adelaide will experience several days with temperatures only reaching the mid to high teens, along with showers and heavy rain.
Millions of Australians are set to experience extreme conditions in the coming days, with contrasting weather patterns across the country. The developing negative Southern Annular Mode (SAM) is the cause, with sudden warming in the stratosphere over Antarctica driving the unusual weather. Residents are advised to stay informed and take necessary precautions.
