海洋模式相互比较项目（OMIP）是耦合模式相互比较项目第六阶段（CMIP 6）中的一个核可项目。OMIP解决CMIP 6科学问题，调查系统模型偏差的起源和后果。它通过提供一个框架来评估（包括系统偏差的评估），理解和改进海洋，海冰，示踪剂和气候和地球系统模型的地球化学成分，为CMIP 6做出贡献。在WCRP气候科学重大挑战（GCs）中，OMIP主要贡献于区域海平面变化和近期（气候/年代际）预测GCs。OMIP提供（a）一个在规定的大气强迫下运行的全球海洋/海冰模型的实验协议;和（B）一个海洋诊断协议，作为CMIP 6的一部分保存。我们在这里集中在OMIP的物理组成部分，与配套文件（Orr等人，2016）详细介绍了惰性化学和交互式地球化学的方法。OMIP实验协议的物理部分遵循年际协调海冰参考实验（CORE-II）。自2009年以来，CORE-I（正常年强迫）和CORE-II（年际强迫）已成为评估全球海洋/海冰模拟和研究强迫海洋气候变率机制的标准方法。OMIP诊断协议适用于CMIP 6的任何海洋模型组件，包括DECK（Klima实验的诊断、评估和表征）、历史模拟、FAFMIP（通量异常强制MIP）、C4 MIP（耦合碳循环气候MIP）（检测和归因MIP），DCPP（Decadal Climate Prediction Project）、ScenarioMIP、High-ResMIP（High Resolution MIP）以及海洋/海冰OMIP模拟。
The Ocean Model Intercomparison Project (OMIP) is an endorsed project in the Coupled Model Intercomparison Project Phase 6 (CMIP6). OMIP addresses CMIP6 science questions, investigating the origins and consequences of systematic model biases. It does so by providing a framework for evaluating (including assessment of systematic biases), understanding, and improving ocean, sea-ice, tracer, and biogeochemical components of climate and earth system models contributing to CMIP6. Among the WCRP Grand Challenges in climate science (GCs), OMIP primarily contributes to the regional sea level change and near-term (climate/decadal) prediction GCs. OMIP provides (a) an experimental protocol for global ocean/sea-ice models run with a prescribed atmospheric forcing; and (b) a protocol for ocean diagnostics to be saved as part of CMIP6. We focus here on the physical component of OMIP, with a companion paper (Orr et al., 2016) detailing methods for the inert chemistry and interactive biogeochemistry. The physical portion of the OMIP experimental protocol follows the interannual Coordinated Ocean-ice Reference Experiments (CORE-II). Since 2009, CORE-I (Normal Year Forcing) and CORE-II (Interannual Forcing) have become the standard methods to evaluate global ocean/sea-ice simulations and to examine mechanisms for forced ocean climate variability. The OMIP diagnostic protocol is relevant for any ocean model component of CMIP6, including the DECK (Diagnostic, Evaluation and Characterization of Klima experiments), historical simulations, FAFMIP (Flux Anomaly Forced MIP), C4MIP (Coupled Carbon Cycle Climate MIP), DAMIP (Detection and Attribution MIP), DCPP (Decadal Climate Prediction Project), ScenarioMIP, High-ResMIP (High Resolution MIP), as well as the ocean/sea-ice OMIP simulations.
