摘要

南极海冰是区域和全球气候的一个极其重要的组成部分。2023 年，海冰面积降至历史最低点，夏季最小值、冬季最大值和中间冻结期的数值都达到了前所未有的水平。在此，我们表明，尽管量化此类事件的罕见程度存在挑战，但在卫星记录的背景下，观测到的极端值确实非常显著，并讨论了一些促成因素。虽然这可能是与人类造成的气候变化有关的海冰减少的一部分，但现在下结论还为时过早。

2023's Antarctic sea ice extent is the lowest on record

Antarctic sea ice is a vitally important part of the regional and global climate. In 2023, sea ice extent fell to record lows, reaching unprecedented values for both the summer minimum, winter maximum and intervening freeze-up period. Here, we show that the extreme values observed were truly remarkable within the context of the satellite record, despite the challenge of quantifying how rare such an event might be, and discuss some contributing factors. While this could be part of a decline in sea ice associated with human-caused climate change, it is too early to say conclusively if this is the case.

期刊介绍： The aim of Weather is to act as a bridge between the interests of those having a professional and a general interest in the weather, as well as between meteorologists and others working in related sciences such as climatology, hydrology and geography. Articles and regular features are written for a wide range of readers, from professional meteorologists to amateur weather observers. While technical language and mathematical content are kept to a minimum, Weather also seeks to inform and to give readers an opportunity to update their subject knowledge. Weather is also the ''house journal'' of the Society and seeks to keep the reader up-to-date with Society news and includes meeting and conference reports, a Readers'' Forum series and occasional Viewpoint articles. Photographs of weather events are an important feature of the journal and the Weather Image feature provides an opportunity to analyse a satellite image or photograph. Weather Log is a summary of the weather of each month by means of meteorological data and weather maps.
