Wind wave interactions have been broadly investigated for their great implications on air sea momentum transfer, whereas our knowledge on those forced by typhoons (hurricanes) is still limited. Accordingly, relationships between wind and wave characteristics were analyzed using observations on the northern South China Sea during four typhoons. An empirical wind wave model was proposed for typhoon induced wind seas which exhibits satisfactory skills in predicting significant wave heights (Hs). Meanwhile, typhoon forced wind wave relation was investigated using the wave growth function. By delineating the relationship between the dimensionless Hs and peak wave period scaled with 10 m and friction wind velocities, simplified functions for the growing and steady wind seas were proposed, respectively. However, great misalignment could occur owing to the contamination of swells resulting from the typhoon's slow translation speed, as well as the extremely short or long radial distance from typhoon centers, indicating the necessity of considering typhoon structures in screening swell influences.

南海北部台风引发的风与浪的关系

中文摘要：风与浪的相互作用对海气动量传输的影响已被广泛研究，而对台风(飓风)引起的风浪相互作用的研究还很有限。因此，由南海北部4次台风期间的观测资料分析了风浪特征之间的关系。提出了一种台风引发风海的经验风浪模型，该模型在预测有效波高(Hs)方面具有较好的能力。同时利用波的生长函数研究了台风强迫的风浪关系。通过描述无量纲Hs与10m波峰周期和摩擦风速之间的关系，分别提出了生长风海和稳定风海的简化函数。然而，由于台风缓慢的平移速度所造成的涌浪污染，以及距台风中心极短或极长的径向距离可能会导致巨大的错位，这表明在筛选涌浪影响时必须考虑台风结构。
