台风浪场的快速模拟是海浪灾害预警的核心工作，本文基于二维波射线理论构建了一种快速的台风浪场预报模型。该模型采用Holland风场模型驱动，在极坐标网格下，使用四阶Runge-Kutta法求解微分方程，得到海浪能量、主波方向和谱峰频率的时空分布。以台风“莲花”(2009)为例运行模型，分析了台风浪场的空间结构和演化过程。模拟结果显示了由群速度共振引起的浪场非对称性，体现了台风下风浪的发展和涌浪的传播，台风高风速区域生成的高能量、高群速的风浪向外传播，在台风低风速区形成涌浪，并作为主导波是该区域混合浪场的主要组分。使用Jason-1高度计数据对模型进行了验证，结果与高度计数据较为吻合，相关系数R=0.79。证明了该模型可以快速有效的对台风浪场进行模拟。
