Regional ecosystem productivity is highly sensitive to inter-annual climate variability, both within and outside the primary carbon uptake period. However, Earth system models lack sufficient spatial scales and ecosystem processes to resolve how these processes may change in a warming climate. Here, we show, how for the European Alps, mid-latitude Atlantic ocean winter circulation anomalies drive high-altitude summer forest and grassland productivity, through feedbacks among orographic wind circulation patterns, snowfall, winter and spring temperatures, and vegetation activity. Therefore, to understand future global climate change influence to regional ecosystem productivity, Earth systems models need to focus on improvements towards topographic downscaling of changes in regional atmospheric circulation patterns and to lagged responses in vegetation dynamics to non-growing season climate anomalies.

山地生态系统生产力对全球环流模式的反应比对气候趋势的反应更多

区域生态系统生产力对初级碳吸收期内外的年际气候变化高度敏感。然而，地球系统模型缺乏足够的空间尺度和生态系统过程来解决这些过程如何在气候变暖中发生变化。在这里，我们展示了欧洲阿尔卑斯山中纬度大西洋冬季环流异常如何通过地形风环流模式、降雪、冬季和春季温度以及植被活动之间的反馈来驱动高海拔夏季森林和草原生产力。因此，要了解未来全球气候变化对区域生态系统生产力的影响，
