极端气候对植被结构和功能构成严重威胁。植被动态受同期气候条件和过去植被状态遗留影响的影响，但它们在驱动季节性极端负异常（NEGs）中的作用尚不明确。本文分析了2000年至2022年卫星衍生的植被数据，将季节性 NEG归因于气候极端和过去植被状态。约 60%的季节性NEGs与气候极端重合。寒冷极端在北方地区四季均主导植被减少，而在温带地区，驱动因素则从春季的极端寒冷转向夏季和秋季的干旱或热浪。与气候极端无关，生物传递效应占季节性NEG的>10%，并增加了长期植被胁迫的可能性，约23%的春季NEG会持续到至少一个后续季节。我们的发现表明，生物遗产延长了短期气候极端的影响，使生态系统对气候变化的反应预测变得复杂。
