Long non-linear waves in a confined basin, induced by transient atmospheric disturbances

In the non-linear statement, the paper studies long waves induced in a confined basin of variable depth by a low atmospheric pressure area, translating at constant speed over the basin. The study is conducted in terms of a non-stationary finite-difference model. Emphasis is made on the behaviour of the wave process after the departure of the disturbance. The dependence of the modal composition of fluid oscillations on the basin parameters and baric disturbances is determined. Translated by Vladimir A. Puchkin.
