抽象的。耦合的谱波模型与非线性相位分辨模型被用来重建2007年11月8日至9日穿越北海的风暴期间的波统计的演变。在这场风暴中，在Ekofisk油田记录到了一个流氓波（称为Andrea波）。该波的特征与挪威国家石油公司1995年1月1日在Draupner平台测量的著名新年波相当。在最近的网格点的Ekofisk场的风暴后报数据在这里作为输入计算的随机实现的海面及其统计特性的演变。使用高阶谱方法（HOSM）使用欧拉方程进行数值模拟。结果进行了比较的Andrea波记录的一些特点，在Ekofisk下看激光测量。
Abstract. A coupling of a spectral wave model with a nonlinear phase-resolving model is used to reconstruct the evolution of wave statistics during a storm crossing the North Sea on 8–9 November 2007. During this storm a rogue wave (named the Andrea wave) was recorded at the Ekofisk field. The wave has characteristics comparable to the well-known New Year wave measured by Statoil at the Draupner platform 1 January 1995. Hindcast data of the storm at the nearest grid point to the Ekofisk field are here applied as input to calculate the evolution of random realizations of the sea surface and its statistical properties. Numerical simulations are carried out using the Euler equations with a higher-order spectral method (HOSM). Results are compared with some characteristics of the Andrea wave record measured by the down-looking lasers at Ekofisk.
