Abstract

Joint analysis of wind wave characteristics derived from Voluntary Observing Ships data (VOS) and the third-generation spectral wave model WAVEWATCH III v.5.16 hindcast is presented. Global distributions of significant wave heights and mean periods in both datasets demonstrate good qualitative and quantitative agreement, especially in regions with a high spatiotemporal density of observations. Simulation results and visually observed wind sea and swell show perfectly consistent patterns of directional steadiness. However, wind sea heights in WW3 are overestimated predominantly in stormy regions, while swell heights are globally underestimated. The reasons for these discrepancies in assessment of wave system components are investigated in the framework of various wave regime analyses.

通过VOS的视觉观察验证海洋风浪全球后播

摘要

提出了根据自愿观测船数据（VOS）和第三代频谱波模型WAVEWATCH III v.5.16后播得出的风波特征的联合分析。在两个数据集中，重要波高和平均周期的全球分布都显示出良好的定性和定量一致性，尤其是在时空观测密度较高的地区。仿真结果和肉眼观察到的风浪和涌浪显示出方向稳定的模式完全一致。然而，第三次世界大战中的风海高度被高估了，而全球范围内的海浪高度被低估了。在各种波浪状态分析的框架内，研究了在评估波浪系统组成部分时出现这些差异的原因。
