Abstract
Horizontal propagation of waves of inertial internal gravity modes in a rotating linearly stratified Boussinesq fluid is studied based upon the linear theory. We employed problems of both a line sink and a point sink flow in a reservoir of finite depth so that the twodimensional and the axisymmetric propagation of modes are investigated. Our consideration is mainly focused on time, space and rotating angular velocity dependence of their propagation speed, horizontal wavenumber and amplitude.
