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).

北冰洋模式相互比较项目(AOMIP)的科学目标是以协调的方式验证和改进北冰洋模式，调查北冰洋和海冰在季节到十年的时间尺度上的可变性，并查明造成观察到的变化的机制。S项目的实际目标是维持和加强已建立的AOMIP国际合作，以减少模型预测中的不确定性(通过协调的实验和研究来验证和改进模型)；支持北极一整套模型的综合；组织科学会议和研讨会；与其他MIP合作，特别侧重于模型改进和分析；向更广泛的社区传播AOMIP工作的结果；并培训新一代海洋和海冰模型人员。AOMIP的主要活动将包括综合(找出模型中一致的错误，提出解决方案，并找到最合适和最可靠的耦合冰？用于完全耦合的区域和全球气候模型的海洋模型)和过程研究(改进模型，利用模型结果和观测调查过程。特别是，AOMIP将侧重于如何更好地模拟产生将常年海冰与大西洋水层隔绝所需的层结的北极盐跃层，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。将继续研究潮汐在北极气候中的作用、应力驱动和对流驱动混合的参数化以及小中尺度和大尺度湍流(涡旋和旋涡)的作用。
