摘　　要：基于第3代数值海浪模型SWAN,采用自嵌套的方法提供谱型边界,对渤海"98.04"寒潮大风引起的风浪过程进行了数值模拟研究。将数值模拟结果与T/P卫星高度计观测资料和近岸浮标实测资料(波高和波向)进行了较为详细的比较,并分析了风浪要素的时空分布。结果显示风浪要素的模拟值与实测值吻合良好,表明SWAN模型能较好地再现渤海寒潮期间风浪的时空分布。This paper uses self-nested method to provide the spectral-type boundary based on the third generation numerical wave model SWAN to conduct a numerical simulation research on the process of wave caused by ＂98·04＂ cold wave and strong wind in Boha Sea. A detailed comparison of the numerical simulation data with the observation data collected by T/P satellite altimeter and the data actually measured by near shore buoys is made and the time-space distribution of wave elements is analyzed. The results show that the simulation values of wave elements are in good agreement with the actually measured values, which indicates that the SWAN model can preferably reflect the time-space distribution of the wave in the period of cold wave in Bohai Sea.
