Abstract：By interpolating CCMP sea surface wind field into a background wind field with spatial resolution of 5'× 5'and temporal resolution of 1h,new wind fields with different compound radii were builtcombining the Hollandempirical model.With these new wind fields,the SWAN model was used to simulating the 13th typhoon Megi in 2010,and the simulated winds and wave heights were verified with the satellite data.The simulated results werebasicallyin agreement withthe satellitedata,and the compound radius of 100kmhadthe best simulation result.By comparing different parameterizations for drag coefficient in SWAN,it was found that the influence ofthe different parameterizations on model results was generally reflected in gale regionin terms of wave height comparing to satellitealtimeter data.The new version of SWAN41.01 hadmorereasonableresult for wave height if the wind energy input was amended.
