2022年3月,一股史无前例的热浪袭击了南极洲东部,最高温度比气候学高出39摄氏度,这是全球有记录以来最大的温度异常。我们调查了热浪的原因,气候变化的影响,以及气候模式模拟这种事件的能力。这场热浪被巧妙地预测出来,是由一种高度异常的大范围环流模式造成的,该模式在4天内将一个澳大利亚气团平流到南极洲东部,并产生了创纪录的大气热通量。南大洋海面温度异常对热浪波幅的影响很小。气候模式的模拟未能模拟如此大的温度异常,主要是由于其大尺度环流变率的偏差,这为未来在模拟极端热浪方面改进模式提供了一条途径。气候变化使热浪升高了2摄氏度,21世纪末热浪可能会额外升高5-6摄氏度,这增加了东南极内陆接近融化的温度的可能性。
An unprecedented heatwave impacted East Antarctica in March 2022, peaking at 39°C above climatology, the largest temperature anomaly ever recorded globally. We investigate the causes of the heatwave, the impact of climate change, and a climate model's ability in simulating such an event. The heatwave, which was skillfully forecast, resulted from a highly anomalous large‐scale circulation pattern that advected an Australian airmass to East Antarctica in 4 days and produced record atmospheric heat fluxes. Southern Ocean sea surface temperatures anomalies had a minimal impact on the heatwave's amplitude. Simulations from a climate model fail to simulate such a large temperature anomaly mostly due to biases in its large‐scale circulation variability, showcasing a pathway for future model improvement in simulating extreme heatwaves. The heatwave was made 2°C warmer by climate change, and end of 21st century heatwaves may be an additional 5–6°C warmer, raising the prospect of near‐melting temperatures over the interior of East Antarctica.
