Polar Amplification Model Intercomparison Project

北极海冰的消失是人为气候变化最引人注目的表现之一。深刻的环境变化已经影响到北极居民和生态系统。越来越多的科学证据，包括PI的许多重要论文，表明海冰减少的影响将远远超出两极。北极海冰损失与极端中纬度气候之间的联系已成为一个日益受到学术研究和社会关注的领域。然而，仍然存在重大的知识差距，需要紧急关注；特别是，在不同的气候模型中，对海冰损失及其基础物理原因的反应的稳健性。极地放大模式比对项目（PA-MIP）将极大地促进对北极和南极海冰损失的气候响应的理解和建模。它将使人们能够更深入地了解过去和未来极地变化的原因和全球影响，以及所涉及的物理机制。PA-MIP是英国和国际科学家的新颖和独特的合作。为了促进卓有成效的合作和推动卓越的研究，该提案支持两项关键活动：借调计划和综合研讨会，这两项活动都直接有利于nerc资助的科学。

The loss of Arctic sea-ice is one of the most compelling manifestations of man-made climate change. Profound environmental change is already affecting Arctic inhabitants and ecosystems. Increasing scientific evidence, including many key papers by the PI, suggests the impacts of sea-ice loss will be felt way beyond the poles. Linkages between Arctic sea-ice loss and extreme mid-latitude weather have become an area of increasing scholarly enquiry and societal interest. Yet, significant knowledge gaps remain that demand urgent attention; in particular, the robustness of response to sea-ice loss - and its underpinning physical causes - across different climate models.The Polar Amplification Model Intercomparison Project (PA-MIP) will significantly advance the state-of-the-art in understanding and modelling the climate response to Arctic and Antarctic sea-ice loss. It will enable deeper understanding of the causes and global effects of past and future polar change, and the physical mechanisms involved. PA-MIP is a novel and unique collaboration of UK and international scientists. To promote fruitful collaboration and drive research excellence, this proposal supports two key activities: a secondment scheme and a synthesis workshop, both with direct benefit to NERC-funded science.
