摘要(Abstract)：

渤海是中国主要的海冰存在区域,同时渤海地区也是我国的经济重心,海上交通发达,经济活动频繁。海冰的存在对于海上波浪情况会产生重要的影响。随着渤海海冰范围的缩减,包括航运和海上建设在内的经济发展也在持续增加,这需要可靠的波浪和海冰预测来应对这种不断变化的环境,同时对经济活动影响最重大的海冰边缘区的波浪模拟变得越来越重要。本文使用WAVEWATCH ■不同海冰模型对渤海的海浪进行了模拟,并研究比较了不同海冰模型的差异。研究发现,在海冰模型中,其IC0和IC1均不是真实的理论模型,它们不具备模拟海冰覆盖海域下海浪的能力。IC2和IC3为理论模型,其衰减率随着频率变化,并且可以对高频部分进行有效的衰减,同时在低频区域的衰减率也处于合理的范围,而IC0与IC1则无法做到。针对海冰覆盖海域的海浪模拟,应首选IC2或IC3,同时根据实地海冰的情况来确定参数。
