Numerical study of typhoon wave distribution characteristic of the Keelung port

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.
