| Zusammenfassung |
| A modern version of
a numerical wind wave model of the fourth generation is constructed for a
case of deep water. The following specific terms of the model source
function are used: (a) a new analytic parameterization of the nonlinear
evolution term proposed recently in Zakharov and Pushkarev (1999); (b) a
traditional input term added by the routine for an atmospheric boundary
layer fitting to a wind wave state according to Makin and Kudryavtsev
(1999); (c) a dissipative term of the second power in a wind wave spectrum
according to Polnikov (1991). The direct fetch testing results showed an
adequate description of the main empirical wave evolution effects.
Besides, the model gives a correct description of the boundary layer
parameters' evolution, depending on a wind wave stage of development.
This permits one to give a physical treatment of the dependence mentioned.
These performances of the model allow one to use it both for application
and for investigation aims in the task of the joint description of wind
and wave fields. |
