Wave hindcasting study of so-called ‘Yorimawari-waves’, huge swell caused by the low pressures in February 2008 was conducted by using the meso-scale meteorological model (MM5) and the third generation wave spectrum models (WW III and SWAN). It is considered that both the reproduction of the wind fields of wide region precisely and the estimation of the swell propagations from north are the most important factors of such abnormal wave simulation. Numerical simulation results indicate that swell from NE and wind waves from NW play a key role of the generation of Yorimawari-waves and it is clarified that the wave model need to improve its diffractive effects more for swell-dominant wave field simulation.
