| 摘 要： | 本文将目前先进的大尺度海洋、海冰模式(NEMO3.6和LIM3)应用于北大西洋–北冰洋–北太平洋(简称NAPA)，并进行了试验后报模拟。所建立的模式NAPA1/4和NAPA1/12的水平分辨率分别为(1/4)°和(1/12)°经、纬度，计算范围覆盖太平洋45°N以北海区、整个北冰洋及北大西洋；其中，NAPA1/4和NAPA1/12在北大西洋的边界分别为26°N和7°N。目前，已利用NAPA1/4完成了1993–2015年的后报模拟。本文基于观测数据和已发表文献对模拟结果中的北冰洋海冰变化、环流结构以及水文特征进行了校验。结果表明，NAPA1/4能够再现北冰洋的主要热力与动力过程，可以用来分析海冰、水团、大西洋/太平洋入/出流等的季节与年际变化规律。利用NAPA1/12进行了1993–1996年的模拟计算。初步结果分析表明，提高分辨率可更为精细地刻画北冰洋的海冰、水团和环流的结构。

| Abstract: | Coupled ocean and sea-ice models, developed based on Version 3.6 of the Nucleus for European Modelling of the Ocean (NEMO), with the sea-ice component being Version 3 of Louvain-la-Neuve Sea Ice Model (LIM), are applied for hindcast simulations covering the North Atlantic-North Pacific-Arctic Oceans (NAPA). The two model configurations, NAPA1/4 and NAPA1/12, have nominal horizontal resolutions of (1/4)° and (1/12)° in latitude/longitude, respectively. The model domains cover the Pacific Ocean north of 45°N, the whole Arctic, and the North Atlantic north of 26°N for NAPA1/4 and 7°N for NAPA1/12. A decade-long hindcast from 1993 to 2015 using NAPA1/4 has been completed. The hindcast results of sea-ice, circulation and hydrography variations in the Arctic Ocean are evaluated with available observational data and previously published results. The evaluation suggests that NAPA1/4 possesses reasonable skills in reproducing the key thermal and dynamic processes, and can be applied to study the seasonal and inter-annual variations of sea-ice, water masses, and Atlantic/Pacific inflows/outflows. Preliminary analysis of the NAPA1/12 hindcast during 1993-1996 suggests that increasing horizontal resolution simulates more details of the spatial structures of sea-ice, water-mass properties, and ocean circulation. |
