AbstractThe project is an integrated statistical analysis of a comprehensive set of long time series from the Arctic and subpolar North Atlantic. These multivariate records include meteorological and oceanographic measurements, sea ice observations and climate indices. The project data set will comprise: a subset of the multidecadal to century-scale 'Unaami' Data Collection, and a set of relatively unknown, century-scale time series from the subpolar North Atlantic (Nordic Seas, Greenland, Iceland, Faroe Islands and Norway) and Arctic that is new to the US community. These data will be organized and analyzed using a comprehensive set of advanced time-frequency statistical methods including organized temporal and spatial patterns of variability and covariability in the ocean-ice-atmosphere system over the past 50-200 years. The work will focus on modes other than the Arctic / North Atlantic Oscillation (AO/NAO), including the multidecadal low-frequency oscillation. To further understanding of the mechanisms, the synthesis will use new output from multi-century model runs from the first coupled atmosphere-ocean general circulation model (AOGCM) with independent stretched-coordinate systems for the atmosphere and ocean that have been resolution-optimized for the Arctic and subpolar North Atlantic.

该项目是对北极和亚极地北大西洋一套综合的长时间序列的综合统计分析。这些多变量记录包括气象和海洋测量、海冰观测和气候指数。该项目的数据集将包括：数十年至世纪尺度“Unaami”数据集合的子集，以及一组相对未知的、世纪尺度的北大西洋次极(北极海、格陵兰、冰岛、法罗群岛和挪威)和北极的时间序列，这对美国社区来说是新的。这些数据将利用一整套先进的时间-频率统计方法进行组织和分析，其中包括过去50-200年间海洋-冰-大气系统变率和协变率的有组织的时间和空间模式。这项工作将侧重于北极/北大西洋涛动(AO/NAO)以外的其他模式，包括数十年的低频振荡。为了进一步了解这些机制，合成将使用来自第一个耦合大气-海洋环流模式(AOGCM)的多世纪模式的新输出，该模式具有独立的大气和海洋伸展坐标系，这些坐标系已针对北极和亚极地北大西洋的分辨率进行了优化。
