By using the latest generation atmospheric reanalysis dataset (ERA5) from the European Centre for Medium-Range Weather Forecast, a numerical wave simulation system based on SWAN model for the western shelf of the Yellow Sea (YS) is established. A thorough calibration is conducted in order to satisfy both modeling accuracy and computational efficiency. Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) analysis is used to determine the optimal choice from heterogeneous options of source terms. Jassens's formulas for wind input and whitecapping and JONSWAP's formula for bottom frictional dissipation are found most suitable. Wave parameters and wave spectra from buoy records and satellite observations are combined for model validation. Results indicate that the ERA5 reanalysis wind outperforms its early generation (ERA-Interim) for offsetting the underestimated wave heights (bias decreases by up to 42%) and wave period (bias decreases by up to 7%) for the inner shelf. ERA5 is found better reproducing the extreme wave simulation whereas could also cause slight overestimation on the shoals for the breeze induced wind-seas. Due to the complex bathymetry of the western inner-shelf of the YS, calibrated bottom friction coefficients vary for winter and summer, which could be relevant to the different directions of the prevailing winds.

利用欧洲中期天气预报中心最新一代大气再分析数据集（ERA5），建立了基于SWAN模型的黄海西部陆架（YS）数值波浪模拟系统。为了同时满足建模精度和计算效率，进行了彻底的校准。通过与理想解决方案的相似性（TOPSIS）分析的顺序偏好技术用于从源项的异构选项中确定最佳选择。Jassens 的风输入和白顶公式以及 JONSWAP 的底部摩擦耗散公式被认为是最合适的。结合来自浮标记录和卫星观测的波浪参数和波浪谱以进行模型验证。结果表明，ERA5 再分析风在抵消内陆架被低估的波高（偏差减少高达 42%）和波周期（偏差减少高达 7%）方面优于其早期生成 (ERA-Interim)。发现 ERA5 能更好地再现极端波浪模拟，但也可能导致微风引起的风海对浅滩的轻微高估。由于 YS 西部内陆架的复杂水深测量，校准的底部摩擦系数在冬季和夏季有所不同，这可能与盛行风的不同方向有关。发现 ERA5 更好地再现了极端波浪模拟，但也可能导致微风引起的风海对浅滩的轻微高估。由于 YS 西部内陆架的复杂水深测量，校准的底部摩擦系数在冬季和夏季有所不同，这可能与盛行风的不同方向有关。发现 ERA5 能更好地再现极端波浪模拟，但也可能导致微风引起的风海对浅滩的轻微高估。由于 YS 西部内陆架的复杂水深测量，校准的底部摩擦系数在冬季和夏季有所不同，这可能与盛行风的不同方向有关。
