连接海洋-大气变率和陆地生产力的机制途径在理论上已经建立，但在经验上量化仍然具有挑战性。这种量化将大大改进对陆地碳固存变化的评估和预测，以响应动态引起的极端气候。北大西洋-欧洲地区的急流纬度（JSL）提供了一个综合的、强大的物理框架，它综合了气候变化，而不是由大气环流模式单独解释的。夏季南北JSL位移对整个欧洲的地表气候影响并不均匀，而是在森林生产力和径向生长异常方面形成西北-东南偶极子。北大西洋东部-欧洲区域（5-40E）夏季JSL变异对欧洲山毛榉的影响最大，导致模型总初级生产力的异常高达30%，径向树生长的异常高达50%。JSL移动对陆地碳通量的净影响取决于森林密度、碳储量和跨生物地理区域的生产力不平衡。在这里，作者表明，夏季欧洲上空的极端急流位置在欧洲西北部和东南部之间形成了山毛榉森林生产力偶极子，并可能导致森林碳吸收和生长的区域异常。
The mechanistic pathways connecting ocean-atmosphere variability and terrestrial productivity are well-established theoretically, but remain challenging to quantify empirically. Such quantification will greatly improve the assessment and prediction of changes in terrestrial carbon sequestration in response to dynamically induced climatic extremes. The jet stream latitude (JSL) over the North Atlantic-European domain provides a synthetic and robust physical framework that integrates climate variability not accounted for by atmospheric circulation patterns alone. Surface climate impacts of north-south summer JSL displacements are not uniform across Europe, but rather create a northwestern-southeastern dipole in forest productivity and radial-growth anomalies. Summer JSL variability over the eastern North Atlantic-European domain (5-40E) exerts the strongest impact on European beech, inducing anomalies of up to 30% in modelled gross primary productivity and 50% in radial tree growth. The net effects of JSL movements on terrestrial carbon fluxes depend on forest density, carbon stocks, and productivity imbalances across biogeographic regions. Here the authors show that extremes in the summer jet stream position over Europe create a beech forest productivity dipole between northwestern and southeastern Europe and can result in regional anomalies in forest carbon uptake and growth.
