Wave Climate Hindcasts for the Bohai Sea, Yellow Sea, and East China Sea

摘要

To investigate wave climate of the Bohai Sea, Yellow Sea, and East China Seas, the third-generation wave model Simulated Waves Nearshore (SWAN) is used to simulate waves for the period 1990 to 2011. The spatial resolution of BYECS wave modelling is 1' in both longitude and latitude. The wind parameters used to simulate the waves are obtained from the Weather Research and Forecasting Model. The results are validated using observational data from seven measurement stations. The spatial distributions of the largest and mean significant wave height within the 22 year period are given, and the spatial distribution of the largest significant wave height of the four seasons is specified. Furthermore, significant wave height is analyzed under mean annual averaged wave conditions for all four seasons. As an example of the application of the hindcast wave data, further details of the wave parameters in Zhangjiapu are presented.
