2. 摘要
北极气候正在迅速变暖，但极端天气事件导致重大生态系统扰动的长期变化尚不十分了解。通过利用跨越过去七十年的先进大气再分析，我们表明，在陆地北极的许多地区，极端天气事件的频率急剧上升。我们发现过去30年生物气候极端的空间变异显著，包括高北极地区干旱增加，以及受冬季变暖和降雪事件影响的更大区域，尤其是在欧洲北极地区。在北极区域的三分之一区域，此类极端事件直到最近才开始发生。因此，北极正进入一个生物气候极端的新时代，可能对寒冷生态系统产生严重后果。
原文摘要（English）
The Arctic climate is rapidly warming, but long-term changes in extreme weather events that cause major ecosystem disturbances are not well understood. Here, by using a state-of-the-art atmospheric reanalysis spanning the past seven decades, we show that, in many parts of the terrestrial Arctic, the frequency of extreme weather events has increased sharply. We found pronounced spatial variability in bioclimatic extremes during the past 30 years, including more droughts in the high-Arctic and greater area affected by winter-warming and rain-on-snow events, especially in the European Arctic region. Across one-third of the Arctic domain, such extreme events have only recently begun to occur. Thus, the Arctic is entering a novel era of bioclimatic extremes with likely severe consequences on cold ecosystems.
