A new high‐resolution global analysis product is constructed from a fully coupled surface wave‐tide‐circulation Ocean Model developed by the First Institute of Oceanography Coupled Ocean Model (FIO‐COM). The performance of the FIO‐COM analysis data set is assessed based on comparisons with two other widely used high‐resolution global analysis products (Copernicus marine and environment monitoring service and HYbrid isopycnal‐sigma‐pressure coordinate ocean model), and observations in tropical oceans. Through comparison with observations, the FIO‐COM analysis is shown to be able to accurately capture the large‐scale mixed layer depth (MLD) structures in the tropical oceans during all seasons. Seasonal variations of MLDs can exceed ±80% in the southern and northern tropical oceans (10°‐25°S and 10°‐25°N) in both boreal winter and summer, as inferred from observations and FIO‐COM analysis data. Quantitative assessments of the 20°C isothermal depth, temperature at 5°m depth, and temperature and salinity profiles, among the analyses and in situ observations are also conducted. The capability of the FIO‐COM analysis to reflect the observed sea surface temperature variability during the 2015 El Niño episode is further investigated through comparisons with observations from 19 TAO buoys located in the Niño 3.4 region. All indicate the high quality of the new data set.

高分辨率全球海洋分析的比对：对热带海洋中新合成的评估

由第一海洋学耦合海洋模型研究所（FIO-COM）开发的完全耦合的表面波-潮-环流海洋模型构造了一种新的高分辨率全球分析产品。FIO-COM分析数据集的性能是根据与其他两种广泛使用的高分辨率全球分析产品（Copernicus海洋和环境监测服务以及Hybrid等速比合-σ-压力坐标海洋模型）的比较以及热带海洋的观测进行评估的。通过与观测值的比较，表明FIO-COM分析能够准确捕获所有季节热带海洋中的大型混合层深度（MLD）结构。在冬季和夏季，南部和北部热带海洋（10°-25°S和10°-25°N）的MLD的季节性变化可能超过±80％，根据观察和FIO-COM分析数据推断。在分析和现场观察中，还对20°C等温深度，5°m深度处的温度以及温度和盐度分布进行了定量评估。FIO-COM分析能够反映2015年观测到的海表温度变化的能力通过与位于Niño3.4地区的19个TAO浮标的观察结果进行比较，进一步调查了ElNiño事件。所有都表明新数据集的高质量。
