北极的持续变化是否影响到北方中纬度地区的风型和极端天气事件的发生？大气环流的混乱本质使我们无法轻易找到答案。这一主题是一个重大的科学挑战，因为北极温度持续上升是人为气候变化的一个不可避免的方面。我们提出了一个观点，拒绝简单的因果关系的途径，并注意到在解释大气动力学诊断的挑战。我们提出了一个前进的方向，基于理解导致北极和中纬度天气和气候联系的不确定性的多种过程。我们强调科学进步和与更广泛公众沟通的社区协调。
Are continuing changes in the Arctic influencing wind patterns and the occurrence of extreme weather events in northern mid-latitudes? The chaotic nature of atmospheric circulation precludes easy answers. The topic is a major science challenge, as continued Arctic temperature increases are an inevitable aspect of anthropogenic climate change. We propose a perspective that rejects simple cause-and-effect pathways and notes diagnostic challenges in interpreting atmospheric dynamics. We present a way forward based on understanding multiple processes that lead to uncertainties in Arctic and mid-latitude weather and climate linkages. We emphasize community coordination for both scientific progress and communication to a broader public.
