平流层变暖事件极为罕见,扰乱了南极洲的极地旋涡,改变了澳大利亚各地的天气模式,有可能出现极端状况。 A rare stratospheric warming event has disrupted Antarctica's polar vortex, altering weather patterns across Australia with potential for extreme conditions.

南极洲上空一次罕见的突发平流层升温事件破坏了极地旋涡,导致高层大气温度急剧上升,并改变了澳大利亚各地的天气模式。 A rare sudden stratospheric warming event over Antarctica has disrupted the polar vortex, causing a sharp temperature rise in the upper atmosphere and altering weather patterns across Australia. 这种现象自2002年以来仅出现两次,削弱了极地旋涡,转移了寒冷的战线和向北的西风。 This phenomenon, occurring only twice since 2002, has weakened the polar vortex, shifting cold fronts and westerly winds northward. 南部地区,如塔斯马尼亚州、维多利亚州和南澳大利亚州,降雨量、强风和不季节性温暖日可能增加,而东澳大利亚州由于干燥空气和强风而面临更干燥的条件和更大的火灾风险。 Southern regions like Tasmania, Victoria, and South Australia may experience increased rainfall, strong winds, and unseasonably warm days, while eastern Australia faces drier conditions and heightened fire risk due to dry air and strong winds. 预计这种影响将持续数周,使季节性预报复杂化,并增加极端天气的可能性。 The impact is expected to persist for weeks, complicating seasonal forecasts and increasing the likelihood of extreme weather.
