Unsteady motion of point vortex in a layer of stratified fluid of a finite thickness

Applied hydromechanics, Vol. 14 (86) ¹ 4, (2012) p.65-74
The linear problem of non-stationary movement of two-dimensional vortex from the state of rest in the layer of stratified medium of finite thickness, a density of wich changes in accordance with exponential law, is solved. A horizontal motion of a vortex with constant velocity from the initial moment of time is studied. The solution is provided in quadrature. The peculiarities of formation of the amplitude pattern of disturbed motion and a change of a power being utilized by the vortex for emitting the energy of the internal waves are analyzed.
