江苏沿海台风浪数值模拟

构建CCMP再分析风场与Holland经验台风风场的叠加风场作为海浪的驱动风场，建立SWAN自嵌套模型对影响江苏沿海的典型台风"梅花"引起的台风浪过程进行模拟。在得出风场叠加方式的基础上，设计3种订正系数方案及3种权重系数方案共9种风场构建方案，分别对东中国海进行台风浪模拟并结合Jason-1卫星高度计观测的有效波高数据进行比较分析，实验结果显示各方案有效波高的相对误差最大可相差3%。选取最佳方案的模拟结果为嵌套区域提供波谱边界条件，对嵌套区域的模拟结果表明:模拟值与浮标实测资料吻合较好；台风经过江苏沿海期间，近岸海域最大波高可达5~6 m，中北部海域波浪以涌浪为主，而南部海域则以风浪为主。

Numerical simulation of typhoon wave in Jiangsu coastal area

Based on the driven wind incorporating the Cross Calibrated Multi-Platform remotely sensed wind and Holland typhoon model, nested typhoon wave model is developed by SWAN to simulate the waves caused by "MUIFA".After obtaining the incorporation way, 9 schemes in wind establishment, 3 calibration coefficient schemes and 3 weighting coefficient schemes are employed, then they are conducted to the wave simulation in East China Sea and the results are compared with the significant wave height of Jason-1 altimeter.The results show that the relative error of significant wave height can have a difference of 3%.Choose the result of the best scheme to provide wave spectrum boundary condition for the nested domain and the results demonstrate that the computation results fit the buoy data well, the wave height in Jiangsu coastal area can reach 5~6 m, the northern and central Jiangsu coastal areas are dominated by swell whereas the southern areas are greatly affected by wind wave during typhoon "MUIFA".
