The numerical modelling of local density disturbance in shear flow of linearly stratified fluid has been carried out. To describe the flow two mathematical models were used: Euler equations in Oberbeck-Boussinesq approximation and linear model. The numerical results demonstrate a dependence of flow parameters on Richardson number. Presence of shear flow leads to essential distortion of motion pattern.
