Wind field under Jelesnianski tropical cyclone is applied to simulate the typhoon field. The SWAN model is based on the action balance equation, which is used to calculate the potential threatening typhoon waves in the sea region during 1951-2010. The model is well verified using field wind and wave data. With the results of the typhoon simulation, the wave height data is analyzed with regression analysis, and comparison of the simulated wave parameters with the measured values show good agreement. This research can provide scientific basis for projects in the sea area in the future.
