| Abstract: | The paper addresses the plane linear problem on generation of an internal wave in a continuously stratified ocean by a moving
atmospheric front. The front exhibits air pressure perturbations, as well as the field of tangential wind stress. In the frame
of a model for the planetary atmospheric boundary layer, a relationship between the air pressure and wind fields has been
derived, generalizing Ackerbloom's formulae for the case of a moving atmospheric anomaly. Using the Fourier transform, a relation
has been obtained for the wave's signature in the wake of a moving atmospheric perturbation, and the respective analysis has
been performed. Numerical estimates of the internal wave amplitudes have been acquired for the mean density stratification
in the Kuril-Kamchatka region. Comparative analysis of the effectiveness of wave signature generation by the moving areas
of surface pressures and tangential wind stresses has been carried out. It has been demonstrated that the latter field determines
the effectiveness of baroclinic wave signature generation.
