| Zusammenfassung |
| The measurements of the vertical structure of hydrological fields and internal
waves on the Levantine Sea's polygon in the Mediterranean, obtained in the 27-th cruise of
the RV "Professor Kolesnikov" in 1991, have been used to estimate the kinematic
and nonlinear characteristics of the internal wave field. Statistical and spatial
distributions of the vertical profiles of the Brunt-Vaisala frequency are described. They
have been used to calculate the coefficients of the Korteweg - de Vries equation. This
equation forms the main model for nonlinear parameters. It is shown that the variations of
the long wave speed propagation and the dispersion parameter are relatively small in
comparison with the variation of the nonlinear parameter. Estimations of the nonlinear
properties of the internal waves, being measured, based on the calculation of the local
Ursell parameter are given. This method can be used for investigation of the internal wave
transformation processes in oceanic regions with horizontal variability of the
hydrophysical fields (temperature, salinity) and sloped sea floor. |
