摘要：

Internal waves generated in an ideal stratified gas under the action of a vortex thread are investigated. The problem is reduced to solving the mixed problem for the nonlinear partial differential equation of the third order for the case of sufficiently slow motions, when acoustic oscillations by comparison of floatability oscillations can be neglected. The stationary solution of this problem is found. Its instability is proven in the linear approximation.
