本文研究了海洋光学特性和太阳衰减对上层海洋温度结构和海洋热含量的影响。我们采用了一个真实的西北大西洋三维海洋环流模型来模拟2017年活跃的大西洋飓风季节的海洋状态。通过将海洋环流预测与传统的基于水类型的太阳能衰减模型或基于固有光学特性（IOP）的模型相结合来进行敏感性实验。对现场海洋温度观测和遥感导出的OHC的验证表明，使用基于IOP的模型进行的海洋模拟在预测海表面温度、上层海洋热结构和OHC方面优于使用传统的基于水类型的模型进行的模拟。针对2017年五场主要飓风得出的OHC-飓风强度关系表明，海洋光学特性和适当太阳衰减模型的应用对于飓风强度的预测非常重要。
This study investigated how ocean optical properties and solar attenuation may affect the upper ocean temperature structure and ocean heat content (OHC). We employed a realistic three‐dimensional ocean circulation model for the northwestern Atlantic to simulate ocean states during the active Atlantic hurricane season of 2017. Sensitivity experiments were performed by coupling the ocean circulation prediction with either a conventional water type‐based solar attenuation model or an inherent optical properties (IOP)‐based model. Validations against in‐situ ocean temperature observations and remote sensing‐derived OHC showed that ocean simulations using the IOP‐based model outperformed simulations using the conventional water type‐based model in predicting sea surface temperature, upper ocean thermal structure, and OHC. An OHC‐hurricane intensity relationship derived for five major hurricanes in 2017 suggests that the ocean optical properties and the application of an appropriate solar attenuation model are important for the forecast of hurricane intensity.
