Application of Reanalyzed Wind Field of Space-borne Scatterometer in Sea Wave Simulation

Abstract

Wave numerical simulations of East China Sea,Eastern Pacific and central Pacific waters near Hawaii are carried out based on third-generation wave model WAVEWATCH Ⅲ,using NCEP/QuikSCAT wind field as model mixed input.In East China Sea,it is obtained that significant wave height and the reference value of buoy has a strong correlation coefficient,and the root mean square error of wave height is about 0.5 m by simulation;In the Pacific waters near the east coast and Hawaii,significant wave height values are generally lower than the reference value of buoy,root mean square error of wave height of different months is between 0.4 and 1.2 m,but the simulation of wave height and the reference value of buoy still has strong correlation.The results show that it is feasible that taking advantage of WAVEWATCH Ⅲ combined NCEP/QuikSCAT mixed wind field to simulate the wave height of East China Sea.However,it is still necessary to consider some non-wind factors in simulation of wave height lies at Pacific Ocean and the eastern open deep waters
