基于修正的Holland台风模型风场,在同化QuikScat/NCEP混合风场基础上,结合高分辨率水深和高精度岸线资料,采用第三代近岸海浪模式SWAN,对影响基隆港邻近海域的两类典型台风过程引起的台风浪进行了数值模拟分析。模拟的两次台风过程中,西北型台风0715号和转向型台风0424号的有效波高与同一时段T/P卫星高度计资料波高的平均相对误差分别为6.5%和5.6%,相关系数分别达到0.972和0.902,台风浪个例模拟精度较高,可为基隆港及其邻近海域台风浪模拟与预报提供一种有效的方法。 |
Based on the QuikScat/NCEP blended wind assimilated by the revised Holland typhoon model wind and the high resolution bathymetry and coastline data,the SWAN model is applied to simulate the typhoon wave generated by typhoon of two typical routines around the Keelung port sea area.The simulation results of the two typhoon process,Typhoon Krosa(2007) and Typhoon Nock-Ten(2004),are compared with the T/P satellite altimeter data,where there exists a mean relative error of 6.5% and 5.6% between them respectively,and the correlation coefficients of them is respectively 0.972 and 0.902.The accuracy of the simulation result is high,which makes it could provide a efficient method of typhoon wave simulation and forecast for the Keelung port. |
