Applications of a Two-Dimensional Model of Submarine Disturbance in an Ocean with a Thin Thermocline

Abstract : The physical assumptions and mathematical framework are given of a simplified, 2-dimensional model of a hydrodynamic disturbance due to passage of a submerged submarine in an ocean characterized by a thin thermocline. Several exploratory applications of the model are described, including estimation of: currents at the surface due to (1) the complex disturbances made by a submarine running slightly 'heavy' above a thin thermocline, and (2) to an oscillating and eventually collapsing wake just below a thin thermocline, and of the energetic efficiency of production of the lowest mode internal wave of a thin thermocline due to wake collapse.
