A simulative study is made to the process of two typhoon waves that affected the sea area near Zhanjiang port based on the third generation of nearshore seawave numerical model SWAN.The wind field demanded by the model is provided after the corresponding typhoon elements,data at gridpoint of NCAR/NCEP,and measurements at individual station are assimilated by the virtue of Tengtian model of typhoon wind field.A boundary of the model's wave spectrum is obtained by the use of self nested method.The results of the two simulations conform well to the observed data,which can provide an improtant reference for modeling forecast of typhoon waves on the sea.
