st with C wc =4.0 is a tunable coefficient. We find this value is so big that much of wave energy is dissipated. In our experiments , we st amended this value C wc =0.15.
4. Improvement of proportionality coefficient α As we all know, transfer of wind energy to the waves is commonly described in SWAN with a resonance mechanism and a feed-back mechanism. In SWAN, the value of the proportionality coefficient is constant in a stationary or non-stationary wind process, although it is variable with different wind process. We find that the proportionality coefficient α in linear growth term of wind growth model plays an unperceived role in the process of wave developing. From the results of computation, we find that it is unseemly that the proportionality coefficient is a constant value.
