| Zusammenfassung |
| A lot of discrete
configurations for the four-wave nonlinear interaction processes have been
calculated and tested by the method proposed earlier in the frame of the
concept of Fast Discrete Interaction Approximation to the Hasselmann's
kinetic integral (Polnikov and Farina, 2002). It was found that there are
several simple configurations, which are more efficient than the one
proposed originally in Hasselmann et al. (1985). Finally, the optimal
multiple Discrete Interaction Approximation (DIA) to the kinetic integral
for deep-water waves was found. Wave spectrum features have been
intercompared for a number of different configurations of DIA, applied to
a long-time solution of kinetic equation. On the basis of this
intercomparison the better efficiency of the configurations proposed was
confirmed. Certain recommendations were given for implementation of new
approximations to the wave forecast practice. |
