The Arctic Ocean Model Intercomparison Project (AOMIP) science goals are to validate and improve Arctic Ocean models in a coordinated fashion and investigate variability of the Arctic Ocean and sea ice at seasonal to decadal time scales, and identify mechanisms responsible for the observed changes. The project?s practical goals are to maintain and enhance the established AOMIP international collaboration to reduce uncertainties in model predictions (model validation and improvements via coordinated experiments and studies); support synthesis across the suite of Arctic models; organize scientific meetings and workshops; conduct collaboration with other MIPs with a special focus on model improvements and analysis; disseminate findings of AOMIP effort to broader communities; and train a new generation of ocean and sea-ice modelers.The major AOMIP activities will include synthesis (to identify consistent errors across models, propose solutions, and find the most suitable and reliable coupled ice ? ocean models for use in fully coupled regional and global climate models) and process studies (to improve models, investigate processes using model results and observations. In particular, AOMIP will focus on how to better model the arctic halocline which creates the stratification necessary to insulate perennial sea ice from the Atlantic Water layer, how to avoid restoring and flux correction, and the role of different mechanisms influencing heat fluxes in the ocean - sea-ice - atmosphere system. Investigation will continue of the tidal role in arctic climate, parameterization of stress-driven and convection-driven mixing and the role of small meso- and large-scale turbulence (eddies and gyres).

北冰洋模型比对项目（AOMIP）的科学目标是以协调的方式验证和改进北冰洋模型，并研究北冰洋和海冰在季节到十年时间尺度上的变化，并确定导致观测到的变化的机制。该项目的实际目标是维持和加强已建立的 AOMIP 国际合作，以减少模型预测的不确定性（通过协调实验和研究进行模型验证和改进）；支持北极模型套件的综合；组织科学会议和讲习班；与其他 MIP 开展合作，特别关注模型改进和分析；将 AOMIP 工作的结果传播给更广泛的社区； AOMIP 的主要活动将包括综合（识别模型之间的一致误差，提出解决方案，并找到最合适和可靠的耦合冰-海洋模型，用于完全耦合的区域和海冰模型）。全球气候模型）和过程研究（改进模型，使用模型结果和观测结果调查过程。特别是，AOMIP 将重点关注如何更好地模拟北极盐跃层，该盐跃层创建了将常年海冰与大西洋水层隔离所需的分层，如何避免恢复和通量校正，以及影响海洋-海冰-大气系统中热通量的不同机制的作用将继续研究北极气候中的潮汐作用、应力驱动和对流驱动混合的参数化以及对流驱动的作用。小中观和大规模湍流（涡流和环流）。
