| The analysis of generation of 3D waves and vorteces in the rotating fluid layer of finite depth is carried out in the framework of linear long wavelength model. The source of disturbance is the small vertical bottom displacements of finite bottom region. The integral expressions for hydrodynamic fields and total energy of fluid motion are found. Some general features of the dynamic process are established. Quantative estimations of the influence of medium rotation on the fluid dynamics are obtained on the basis of calculation of the double integrals for the case of deformations of elliptical bottom form, which take place under a linear law during a finite time. This problem is important for studying the effects accompanying the seismic tsunami wave generation in the ocean. |
