The plane problem of generating of surface and internal seiches in a two-layer fluid by a moving baric front is considered in the framework of the shallow-water theory. The problem is solved by finite differ-ence method for a closed rotating basin of a variable depth. The front propagation excites the barotropic and baroclinic waves in the basin. Their amplitudes depend on the front characteristics (intensity, propa-gation velocity, width), basin geometry and density stratification. The excitation of the baroclinic motion is found to be the most effective at some value of the front propagation velocity. After the front leaves the basin, a packet of internal waves is formed, which propagates from one to the other lateral boundary. The decrease in the width and increase in the baric front velocity result in more efficient internal seiches generation.
