Numerical study of sea waves created by tropical cyclone Jelawat

A numerical study of sea waves generated by tropical cyclone Jelawat is carried out using the cycle 4 version of the WAM. The model domain currently covers the latitudes 20°–45°N and longitudes 115°–135°E, and the model spatial resolution reaches 0.25°×0.25°. Comparison of the model results with buoy observations reveals that the model can fairly reproduce the temporal variation of observed waves. Two-dimensional comparison is also made against the satellite altimeter significant wave heights derived from TOPEX/POSEIDON and ERS-2 data, showing high quality of the model performance.
